Description

本発明は、収納容器内に充填された高圧ガスなどの加圧流体の噴出を制御する加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置に関する。
The present invention relates to a pressurized fluid control mechanism that controls ejection of a pressurized fluid such as a high-pressure gas filled in a storage container, and a pressurized fluid supply device that uses this pressurized fluid control mechanism.

従来、長尺な磁気テープや磁気シートの送り機構、さらには、半導体製造装置などの装置に付着する塵埃を除去するため、ガス噴霧装置が用いられている。この種のガス噴霧装置は、収納容器に充填した加圧流体である高圧ガスを噴射口から噴射するようにしたものであって、収納容器に取り付けたバルブ装置を操作することによって、収納容器に収納された高圧ガスを噴射するように構成されている。   2. Description of the Related Art Conventionally, a gas spray device has been used to remove dust adhering to a long magnetic tape or magnetic sheet feeding mechanism, and further to a semiconductor manufacturing apparatus or the like. This type of gas spraying device is designed to inject high-pressure gas, which is a pressurized fluid filled in a storage container, from an injection port. By operating a valve device attached to the storage container, It is comprised so that the stored high pressure gas may be injected.

そして、加圧流体である加圧ガスを充填した収納容器から加圧ガスを噴出するようにした加圧流体供給装置として特開２００３−１４６３９３号公報に記載されたものがある。この文献に記載される装置は、加圧流体を充填した収納容器であるガスボンベの開口部を閉塞する封板にニードルを突き刺し、ガス噴出孔を形成し、このガス噴出孔を形成したニードルによりガス噴出孔の開閉することによってガスの噴出を制御するようにしている。   Japanese Patent Application Laid-Open No. 2003-146393 discloses a pressurized fluid supply device that ejects pressurized gas from a storage container filled with pressurized gas, which is a pressurized fluid. In the apparatus described in this document, a needle is pierced into a sealing plate that closes an opening of a gas cylinder that is a storage container filled with a pressurized fluid, a gas ejection hole is formed, and a gas is ejected by a needle formed with this gas ejection hole. The ejection of gas is controlled by opening and closing the ejection holes.

ところで、上述の特許文献に記載された加圧流体供給装置は、加圧ガスが充填された収納容器の外部に設けたニードルにより封板に形成したガス噴出孔の開閉を制御するようにしているので、簡単な構成でガスの噴出制御を行うことができる。   By the way, the pressurized fluid supply apparatus described in the above-mentioned patent document controls the opening and closing of the gas ejection hole formed in the sealing plate by the needle provided outside the storage container filled with the pressurized gas. Therefore, gas ejection control can be performed with a simple configuration.

しかし、このような構成を採用した加圧流体供給装置にあっては、ガス噴出孔の開閉を制御するニードルの移動を制御する構成が複雑となってしまっている。   However, in a pressurized fluid supply apparatus that employs such a configuration, the configuration for controlling the movement of the needle that controls the opening and closing of the gas ejection holes is complicated.

また、塵埃を除去するために用いられるガス噴霧装置の如き加圧流体供給装置にあっては、手に持って持ち運びして利用可能な大きさにまで小型化されることが要求されている。   Further, in a pressurized fluid supply device such as a gas spray device used for removing dust, it is required to be carried by hand and downsized to a usable size.

さらに、小型の加圧流体供給装置にあっては、良好な操作性をもって加圧流体の噴出制御を実現するため、大きな操作力を必要とすることなく噴出制御を実現できることが望ましい。
Furthermore, in a small pressurized fluid supply device, it is desirable that the ejection control can be realized without requiring a large operating force in order to realize the ejection control of the pressurized fluid with good operability.


本発明の技術課題は、より簡素な機構で、容易にしかも良好な操作性をもって収納容器に充填された加圧ガスなどの加圧流体の噴出を制御することができ、さらには、機構及び装置自体の小型化を実現できる加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置を提供することにある。
The technical problem of the present invention is that it is possible to control the ejection of a pressurized fluid such as a pressurized gas filled in a storage container easily and with good operability with a simpler mechanism. It is an object of the present invention to provide a pressurized fluid control mechanism capable of realizing miniaturization of the device itself and a pressurized fluid supply apparatus using the pressurized fluid control mechanism.

また、本発明の技術課題は、良好な操作性をもって加圧流体の噴出制御を行うことを可能とする加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置を提供することにある。   In addition, the technical problem of the present invention is to provide a pressurized fluid control mechanism capable of controlling the ejection of pressurized fluid with good operability, and a pressurized fluid supply device using the pressurized fluid control mechanism.

そして、先鋭体は、封止部を噴出孔に嵌合させて噴出孔を閉塞したとき、封止部の先端部側が噴出孔より突出され、この突出された部分が押圧操作されることにより移動操作され噴出孔を開放する。   When the sealing portion is fitted to the ejection hole and the ejection hole is closed, the sharpened body projects by projecting the distal end side of the sealing portion from the ejection hole, and the projected portion is moved by pressing. Operated to open the jet hole.

さらに、本発明に係る加圧流体供給装置は、先鋭体を付勢部材の付勢力に抗して押圧操作して噴出孔を開閉操作する開閉操作機構を備える。   Furthermore, the pressurized fluid supply apparatus according to the present invention includes an opening / closing operation mechanism for opening / closing the ejection hole by pressing the sharp body against the urging force of the urging member.

本発明に係る加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置は、加圧流体が充填される加圧流体収納体内に配設した先鋭体により、封板部に設けた微小な噴出孔を開閉制御するようにしているので、より簡素な機構で、且つ容易に収納容器に充填された加圧ガスなどの加圧流体の噴出を制御することができ、しかも、機構及び装置自体の小型化を実現できる。   A pressurized fluid control mechanism and a pressurized fluid supply device using the pressurized fluid control mechanism according to the present invention are provided on a sealing plate portion by a sharpened body disposed in a pressurized fluid storage body filled with pressurized fluid. Since the opening and closing of the provided fine ejection holes are controlled, it is possible to control the ejection of pressurized fluid such as pressurized gas filled in the storage container with a simpler mechanism, Miniaturization of the mechanism and the device itself can be realized.

特に、本発明に係る加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置にあっては、加圧流体収納体内に配した先鋭体のみによって噴出孔を閉塞するようにしているので、この噴出孔を閉塞する部材に加わる総圧力を小さくできるので、噴出孔の開閉を軽い力で容易に行うことができる。したがって、操作性の良好な加圧流体供給装置を構成することができる。   In particular, in the pressurized fluid control mechanism and the pressurized fluid supply apparatus using the pressurized fluid control mechanism according to the present invention, the ejection hole is closed only by the sharpened body disposed in the pressurized fluid storage body. Therefore, since the total pressure applied to the member that closes the ejection hole can be reduced, the ejection hole can be easily opened and closed with a light force. Therefore, a pressurized fluid supply device with good operability can be configured.

以下、本発明を適用した加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置の実施の形態を説明する。
Hereinafter, an embodiment of a pressurized fluid control mechanism to which the present invention is applied and a pressurized fluid supply apparatus using the pressurized fluid control mechanism will be described.

以下に示す実施の形態は、加圧流体として圧縮炭酸ガスを充填した加圧流体収納体から圧縮炭酸ガスの噴出を制御する加圧流体制御機構及びこの加圧流体制御機構を用いた加圧流体供給装置に適用した例を挙げて説明する。なお、以下の説明では、圧縮炭酸ガスを単に炭酸ガスという。   In the embodiment shown below, a pressurized fluid control mechanism for controlling the ejection of compressed carbon dioxide from a pressurized fluid container filled with compressed carbon dioxide as a pressurized fluid, and a pressurized fluid using this pressurized fluid control mechanism An example applied to the supply device will be described. In the following description, the compressed carbon dioxide is simply referred to as carbon dioxide.

本発明が適用された加圧流体制御機構１は、図１及び図２に示すような加圧流体供給装置２に適用されるものである。この加圧流体供給装置２は、加圧流体として炭酸ガスが充填され、あるいは充填される加圧流体収納体であるガス収納容器３を備える。このガス収納容器３は、圧縮され液化された炭酸ガスが充填されるに足る強度を有するものとして形成され、鉄等の金属を用いて有底の円筒状に形成されている。   A pressurized fluid control mechanism 1 to which the present invention is applied is applied to a pressurized fluid supply device 2 as shown in FIGS. 1 and 2. The pressurized fluid supply device 2 includes a gas storage container 3 that is filled with carbon dioxide gas as a pressurized fluid or is a pressurized fluid storage body to be filled. The gas storage container 3 is formed to have sufficient strength to be filled with compressed and liquefied carbon dioxide, and is formed into a bottomed cylindrical shape using a metal such as iron.

ガス収納容器３は、図２に示すように、容器本体３ａの上端側に筒状の縮径部３ｂが形成されいる。この縮径部３ｂは、容器本体３ａの上端側を絞り成形するようにして形成され、その端部に開口部４が形成されている。そして、縮径部３ｂ内に収納されるようにして加圧流体制御機構１が配設されている。   As shown in FIG. 2, the gas storage container 3 has a cylindrical reduced diameter portion 3b formed on the upper end side of the container body 3a. The reduced diameter portion 3b is formed by drawing the upper end side of the container main body 3a, and an opening 4 is formed at the end thereof. The pressurized fluid control mechanism 1 is disposed so as to be accommodated in the reduced diameter portion 3b.

加圧流体制御機構１が配設されたガス収納容器３は、上下一対のハーフ６，７を組み合わせて構成された容器収納体８に収納されている。この容器収納体８は、合成樹脂の成形体により構成され、収納されるガス収納容器３に対応した円筒状に形成されている。なお、ガス収納容器３は、容器収納体８内で移動変位しないように、上下ハーフ６，７により挟持されるようにして収納されている。   The gas storage container 3 in which the pressurized fluid control mechanism 1 is disposed is stored in a container storage body 8 configured by combining a pair of upper and lower halves 6 and 7. The container storage body 8 is formed of a synthetic resin molded body and is formed in a cylindrical shape corresponding to the gas storage container 3 to be stored. The gas storage container 3 is stored so as to be sandwiched between the upper and lower halves 6 and 7 so as not to move and displace in the container storage body 8.

なお、容器収納体８の上ハーフ６側には、後述するように、加圧流体制御機構１を開閉操作する開閉操作機構９が取り付けられる。   An opening / closing operation mechanism 9 for opening / closing the pressurized fluid control mechanism 1 is attached to the upper half 6 side of the container housing 8 as will be described later.

そして、ガス収納容器３に充填された炭酸ガスＣの噴出を制御する加圧流体制御機構１は、図２及び図３に示すように、ガス収納容器３の縮径部３ｂ内に嵌合されるように取り付けられる弁箱１１を備える。この弁箱１１は、縮径部３ｂに嵌合される筒状の弁箱本体１２と、この弁箱本体１２の上端部側に一体に設けられ、縮径部３ｂの端部の開口部４側を閉塞する封板部１３とを備える。   The pressurized fluid control mechanism 1 that controls the ejection of the carbon dioxide C filled in the gas storage container 3 is fitted into the reduced diameter portion 3b of the gas storage container 3 as shown in FIGS. The valve box 11 is attached. The valve box 11 is provided integrally with a cylindrical valve box main body 12 fitted to the reduced diameter portion 3b and an upper end side of the valve box main body 12, and the opening 4 at the end of the reduced diameter portion 3b. And a sealing plate portion 13 for closing the side.

弁箱本体１２の外周面には、縮径部３ｂの内周面に刻設されたされたネジ部１４にねじ込まれるネジ部１５が形成されている。そして、弁箱１１は、図２に示すように、弁箱本体１２に設けたネジ部１５を縮径部３ｂ側のネジ部１４にねじ込みながら嵌合することによって縮径部３ｂに取り付けられる。   A screw portion 15 is formed on the outer peripheral surface of the valve box main body 12 to be screwed into a screw portion 14 formed on the inner peripheral surface of the reduced diameter portion 3b. Then, as shown in FIG. 2, the valve box 11 is attached to the reduced diameter portion 3b by fitting the screw portion 15 provided on the valve box main body 12 while being screwed into the screw portion 14 on the reduced diameter portion 3b side.

なお、弁箱１１は、合成樹脂、例えばポリアセタール樹脂を用いて形成されている。この合成樹脂製の弁箱１１に形成される一方のネジ部１５の山谷を縮径部３ｂ側のネジ部１４の山谷よりやや大きく形成することにより、一方のネジ部１５が金属製の他方のネジ部１４に弾性変形しながらねじ込まれた状態となる。その結果、弁箱本体１２の外周面と縮径部３ｂの内周面との間が密閉され、弁箱本体１２の外周面側からのガス漏れを防止している。   The valve box 11 is formed using a synthetic resin, for example, a polyacetal resin. By forming a crest of one screw portion 15 formed in the synthetic resin valve box 11 slightly larger than a crest of the screw portion 14 on the reduced diameter portion 3b side, the one screw portion 15 is made of the other metal. The threaded portion 14 is screwed in while being elastically deformed. As a result, the space between the outer peripheral surface of the valve box main body 12 and the inner peripheral surface of the reduced diameter portion 3b is sealed to prevent gas leakage from the outer peripheral surface side of the valve box main body 12.

また、封板部１３は、図２及び図３に示すように、筒状の弁箱本体１２の上端部側の開口部を閉塞するように、弁箱本体１２と一体に形成されている。この封板部１３は、図３に示すように、円盤状に形成され、その外周側に弁箱本体１２の外周径より大きな径を有するフランジ部１６が形成されいる。このフランジ部１６は、弁箱本体１２が縮径部３ｂに嵌合されたとき、縮径部３ｂの上端面に当接し、弁箱１１のガス収納容器３に対する取り付け位置を規制している。   Further, as shown in FIGS. 2 and 3, the sealing plate portion 13 is formed integrally with the valve box main body 12 so as to close the opening on the upper end side of the cylindrical valve box main body 12. As shown in FIG. 3, the sealing plate portion 13 is formed in a disk shape, and a flange portion 16 having a diameter larger than the outer peripheral diameter of the valve box body 12 is formed on the outer peripheral side thereof. When the valve box body 12 is fitted to the reduced diameter portion 3b, the flange portion 16 abuts on the upper end surface of the reduced diameter portion 3b and regulates the mounting position of the valve box 11 with respect to the gas storage container 3.

そして、封板部１３の中心部には、ガス収納容器３に充填された炭酸ガスＣを容器の外部に噴出させるためのガス噴出孔１８が形成されている。このガス噴出孔１８は、ガス収納容器３の縮径部３ｂ内に位置するように配設された弁箱本体１２内を進退する先鋭体１７により開閉制御される。   And in the center part of the sealing board part 13, the gas ejection hole 18 for ejecting the carbon dioxide gas C with which the gas storage container 3 was filled out of the container is formed. The gas ejection hole 18 is controlled to be opened and closed by a sharp body 17 that advances and retreats in the valve box body 12 disposed so as to be positioned in the reduced diameter portion 3 b of the gas storage container 3.

ガス噴出孔１８を開閉制御する先鋭体１７は、細い線状の部材を用いて形成されている。この先鋭体１７は、図２及び及び図３に示すように、基端部側の軸部１７ａの先端側に封止部１９を形成している。この封止部１９は、ガス噴出孔１８に嵌合し、このガス噴出孔１８を密閉する部分であって、軸部１７ａ側から先端側に向かって縮径するようにテーパ部として形成されている。すなわち、封止部１９は、外周面を傾斜面とした先端に向かって先細り状に形成されている。   The sharpened body 17 that controls the opening and closing of the gas ejection hole 18 is formed using a thin linear member. As shown in FIGS. 2 and 3, the sharpened body 17 has a sealing portion 19 formed on the distal end side of the shaft portion 17 a on the proximal end side. The sealing portion 19 is a portion that fits into the gas ejection hole 18 and seals the gas ejection hole 18, and is formed as a taper portion so that the diameter decreases from the shaft portion 17 a side toward the distal end side. Yes. That is, the sealing part 19 is formed in a tapered shape toward the tip with the outer peripheral surface as an inclined surface.

この封止部１９が嵌合するガス噴出孔１８は、図４に示すように、封止部１９の形状に対応して、内周面をテーパ状に形成されている。このガス噴出孔１８は、合成樹脂製の封板部１３に金属製の先鋭体１７を差し込むことによって形成される。なお、ガス噴出孔１８は、このガス噴出孔１８を閉塞するために用いられる先鋭体１７により形成されることが望ましい。このような先鋭体１７によりガス噴出孔１８を形成することにより、ガス噴出孔１８と先鋭体１７の形状とを一致させることができるので、先鋭体１７による密閉性を向上することができる。   As shown in FIG. 4, the gas ejection hole 18 into which the sealing portion 19 is fitted has a tapered inner peripheral surface corresponding to the shape of the sealing portion 19. This gas ejection hole 18 is formed by inserting a metal sharpened body 17 into a sealing plate portion 13 made of synthetic resin. The gas ejection hole 18 is preferably formed by a sharpened body 17 used for closing the gas ejection hole 18. By forming the gas ejection hole 18 with such a sharp body 17, the shape of the gas ejection hole 18 and the sharp body 17 can be matched, so that the sealing performance by the sharp body 17 can be improved.

また、ガス噴出孔１８に嵌合し、このガス噴出孔１８を閉塞する封止部１９は、図２に示すように、ガス噴出孔１８を閉塞したとき、先端部が封板部１３から所定量突出し得るようなテーパ部として形成されている。すなわち、封止部１９は、ガス噴出孔１８に挿入され、先端側から基端側に向かって徐々に径が太くなる傾斜面の中途部がガス噴出孔１８に嵌合して係止されたとき、封止部１９の先端部が封板部１３から所定量突出するような長さを有するテーパ状に形成されている。   Further, as shown in FIG. 2, the sealing portion 19 that fits into the gas ejection hole 18 and closes the gas ejection hole 18 has a distal end portion away from the sealing plate portion 13 when the gas ejection hole 18 is closed. It is formed as a tapered portion that can project a certain amount. That is, the sealing portion 19 is inserted into the gas ejection hole 18, and the middle portion of the inclined surface whose diameter gradually increases from the distal end side toward the proximal end side is fitted into the gas ejection hole 18 and locked. At this time, the tip of the sealing part 19 is formed in a tapered shape having such a length that it projects a predetermined amount from the sealing plate part 13.

そして、封止部１９の封板部１３から突出した部分は、後述するように先鋭体１７をガス噴出孔１８に対し進退させる開閉操作部材２０によって操作される押圧操作部２１として用いられる。   And the part which protruded from the sealing board part 13 of the sealing part 19 is used as the press operation part 21 operated by the opening / closing operation member 20 which advances / retreats the sharpened body 17 with respect to the gas ejection hole 18 so that it may mention later.

また、先鋭体１７は、移動ガイド部として機能する弁箱本体１２内に収納され、この弁箱本体１２によって移動方向がガイドされる移動体２２に支持され、この移動体２２と一体に、ガス噴出孔１８に対し進退する方向の図２中矢印Ｙ1方向及び矢印Ｙ2方向に移動可能に弁箱本体１２内に配設される。したがって、移動体２２は、弁箱本体１２内で移動可能な大きさに形成されている。The sharpened body 17 is housed in a valve box body 12 that functions as a movement guide portion, and is supported by a moving body 22 whose movement direction is guided by the valve box body 12. is disposed movably valve body main body 12 in FIG. 2 in the arrow Y 1 direction and the arrow Y 2 direction in the direction back and forth with respect to the ejection hole 18. Therefore, the movable body 22 is formed in a size that can move within the valve box body 12.

ところで、先鋭体１７は、基端部側の軸部１７ａを円筒状の移動体２２に挿入して支持させ、先端側の封止部１９を移動体２２から突出させて、この移動体２２に取り付けられている。また、先鋭体１７の軸部１７ｂの基端部には係止段部１７ｂが形成されている。先鋭体１７は、係止段部１７ｂを移動体２２の基端面に当接させて取り付けられることにより、封止部１９の移動体２２の先端面から突出する突出量が規制されている。   By the way, the sharpened body 17 inserts and supports the shaft portion 17a on the proximal end side in the cylindrical moving body 22, and projects the distal end side sealing portion 19 from the moving body 22, It is attached. Further, a locking step portion 17 b is formed at the proximal end portion of the shaft portion 17 b of the sharpened body 17. The sharpened body 17 is attached such that the locking step portion 17b is brought into contact with the base end surface of the moving body 22, whereby the protruding amount of the sealing portion 19 protruding from the distal end surface of the moving body 22 is restricted.

そして、先鋭体１７を支持した移動体２２は、図２に示すように、先鋭体１７の先端部側に形成した封止部１９をガス噴出孔１８に挿通させて弁箱本体１２内に配設されている。この弁箱本体１２内に配設された移動体２２は、この移動体２２と弁箱本体１２との間に配設された弾性部材であるコイルバネ２３により、図２中矢印Ｙ1方向に移動付勢されている。すなわち、移動体２２は、この移動体２２に支持された先鋭体１７の先端側の封止部１９がガス噴出孔１８に進入し突出する方向に付勢されている。As shown in FIG. 2, the moving body 22 that supports the sharpened body 17 is arranged in the valve box body 12 by inserting the sealing portion 19 formed on the distal end side of the sharpened body 17 into the gas ejection hole 18. It is installed. The moving body 22 disposed in the valve box body 12 is moved in the direction of arrow Y 1 in FIG. 2 by a coil spring 23 which is an elastic member disposed between the moving body 22 and the valve box body 12. It is energized. That is, the moving body 22 is urged in a direction in which the sealing portion 19 on the distal end side of the sharpened body 17 supported by the moving body 22 enters the gas ejection hole 18 and protrudes.

なお、コイルバネ２３は、図２に示すように、移動体２２の中途部に形成した係止段部２２ａと、弁箱本体１２の基端部側に嵌合されたバネ支持部材２４との間に配設されることにより、封止部１９がガス噴出孔１８から突出する方向に付勢している。   As shown in FIG. 2, the coil spring 23 is formed between a locking step portion 22 a formed in the middle portion of the moving body 22 and a spring support member 24 fitted to the proximal end portion side of the valve box body 12. The sealing portion 19 is biased in a direction protruding from the gas ejection hole 18.

ところで、本発明に係る加圧流体制御機構１は、封板部１３に形成したガス噴出孔１８を、ガス収納容器３内に配設された先鋭体１７の封止部１９のみによって閉塞するようにしている。すなわち、本実施の形態においては、先鋭体１７がガス噴出孔１８に嵌合し、このガス噴出孔１８を閉塞した状態にあるとき、移動体２２は、図２に示すように、弁箱本体１２の中途部に位置し、弁箱本体１２内で浮いた状態におかれている。   By the way, the pressurized fluid control mechanism 1 according to the present invention closes the gas ejection hole 18 formed in the sealing plate portion 13 only by the sealing portion 19 of the sharp body 17 disposed in the gas storage container 3. I have to. In other words, in the present embodiment, when the sharpened body 17 is fitted in the gas ejection hole 18 and the gas ejection hole 18 is closed, the moving body 22 is, as shown in FIG. It is located in the middle part of 12 and is in a state of floating in the valve box body 12.

そして、移動体２２の外周面には、図３に示すように、弁箱本体１２の内周面との間に加圧流体流通路を構成する複数の溝部２５が形成されている。この溝部２５は、移動体２２の基端部側から先端部側に亘って連続して形成されている。このような溝部２５が形成されることにより、ガス収納容器３に充填された炭酸ガスＣは、溝部２５を介して移動体２２の先端面と封板部１３との間の空間２６にも充填され、ガス収納容器３の本体３ａ内と均等な圧力になる。その結果、先鋭体１７をガス噴出孔１８に挿入し圧接させる方向の図２中矢印Ｙ1方向に作用する力は、コイルバネ２３の付勢力と、加圧流体としての炭酸ガスが先鋭体１７に作用する力のみとなる。加圧流体が先鋭体１７に作用する力は、先鋭体１７の断面積に相当する面に作用する力となり、収納容器３に充填される加圧流体の圧力に比し十分に小さなものとすることができる。
As shown in FIG. 3, a plurality of grooves 25 constituting a pressurized fluid flow passage are formed on the outer peripheral surface of the moving body 22 between the inner peripheral surface of the valve box body 12. The groove 25 is formed continuously from the proximal end side to the distal end side of the moving body 22. By forming such a groove portion 25, the carbon dioxide gas C filled in the gas storage container 3 is also filled into the space 26 between the distal end surface of the moving body 22 and the sealing plate portion 13 via the groove portion 25. Thus, the pressure is equal to that in the main body 3a of the gas storage container 3. As a result, the force acting in the direction of the arrow Y 1 in FIG. 2 in the direction in which the sharpened body 17 is inserted into the gas ejection hole 18 and press-contacted is the urging force of the coil spring 23 and the carbon dioxide gas as the pressurized fluid on the sharpened body 17. Only acting force. The force that the pressurized fluid acts on the sharpened body 17 is a force that acts on the surface corresponding to the cross-sectional area of the sharpened body 17 and is sufficiently smaller than the pressure of the pressurized fluid filled in the storage container 3. be able to.

本実施の形態においては、封板部１３に形成されるガス噴出孔１８は、直径を０．３ｍｍ〜１ｍｍ程度の大きさとして形成され、テーパ状の封止部１９が形成される先鋭体１７は、軸部１７ａの直径Ｒ1を１．３ｍｍから０．８ｍｍ程度の太さとして形成されている。そして、収納容器３に充填される液化された炭酸ガスの圧力は、概ね７０気圧程度である。このような加圧炭酸ガスによる先鋭体１７に作用する力は、４００ｇ〜６００ｇ程度となる。In the present embodiment, the gas ejection holes 18 formed in the sealing plate portion 13 are formed with a diameter of about 0.3 mm to 1 mm, and the sharpened body 17 in which the tapered sealing portion 19 is formed. Is formed with a diameter R 1 of the shaft portion 17a of about 1.3 mm to 0.8 mm. And the pressure of the liquefied carbon dioxide gas with which the storage container 3 is filled is about 70 atm. The force acting on the sharpened body 17 by such pressurized carbon dioxide gas is about 400 g to 600 g.

そして、先鋭体１７は、ガス噴出孔１８を閉塞した状態を維持する程度の挿入力で図２中矢印Ｙ1方向に押圧されていれば、ガス噴出孔１８を密閉しガス漏れを防止することができる。本実施の形態においては、先鋭体１７は、１ｋｇ〜２ｋｇ程度の押圧力で図２中矢印Ｙ1方向に押圧されていれば、炭酸ガスの流出を防止してガス噴出孔１８を閉塞しておくことが可能である。本実施の形態においては、ガス噴出孔１８を閉塞する方向に先鋭体１７を付勢する付勢部材としてのコイルバネ２３は、１ｋｇ〜１．５ｋｇ程度の付勢力を有するものを用いるのみで足りる。Then, sharp body 17, if it is pressed in FIG. 2 in the arrow Y 1 direction insertion force enough to maintain a state of closing the gas ejection holes 18, to prevent gas leakage sealing the gas injection holes 18 Can do. In the present embodiment, if the sharpened body 17 is pressed in the direction of the arrow Y1 in FIG. 2 with a pressing force of about 1 kg to 2 kg, the outflow of carbon dioxide gas is prevented and the gas ejection hole 18 is blocked. It is possible to leave. In the present embodiment, it is sufficient to use a coil spring 23 having a biasing force of about 1 kg to 1.5 kg as a biasing member that biases the sharpened body 17 in the direction of closing the gas ejection hole 18.

このように、先鋭体１７に作用する力が小さくなるので、ガス噴出孔１８を閉塞した状態にある先鋭体１７を、ガス噴出孔１８を開放させる方向に移動させる力が小さくて済むことになる。そして、先鋭体１７を移動させる力を小さくすることができることから、ガス収納容器３に充填された加圧流体である炭酸ガスの噴出の制御を行う機構を簡素なものとすることができ、しかも小さい力で行うことができるので、良好な操作性を有する噴出制御機構を構成することができる。 そして、弁箱１１にはガス噴出孔１８を囲むように筒状の操作部材挿通部２７が一体に形成されている。この操作部材挿通部２７には、ガス噴出孔１８から突出される先鋭体１７に形成した封止部１９の先端側が臨まされる。また、操作部材挿通部２７は、ガス噴出孔１８から突出した封止部１９の保護を図るとともに、ガス噴出孔１８を開閉操作する開閉操作機構９を構成する開閉操作部材２０が挿通されて進退する部分となる。   As described above, since the force acting on the sharpened body 17 is reduced, the force for moving the sharpened body 17 in the state in which the gas ejection hole 18 is closed in the direction of opening the gas ejection hole 18 can be reduced. . And since the force which moves the sharpened body 17 can be made small, the mechanism which controls the ejection of the carbon dioxide gas which is the pressurized fluid with which the gas storage container 3 was filled can be simplified, and Since it can be performed with a small force, an ejection control mechanism having good operability can be configured. The valve box 11 is integrally formed with a cylindrical operation member insertion portion 27 so as to surround the gas ejection hole 18. The operation member insertion portion 27 faces the distal end side of the sealing portion 19 formed on the sharpened body 17 protruding from the gas ejection hole 18. The operation member insertion portion 27 protects the sealing portion 19 protruding from the gas ejection hole 18 and advances and retracts when the opening / closing operation member 20 constituting the opening / closing operation mechanism 9 for opening / closing the gas ejection hole 18 is inserted. It becomes a part to do.

さらに、操作部材挿通部２７の先端側には、ガス噴出孔１８から噴射される炭酸ガスを噴射するノズル３１が設けられたノズル体３２が取り付けられる。このノズル体３２は、基端部側に操作部材挿通部２７に嵌合する筒状の嵌合部３３が形成され、上端側に開閉操作部材２０が挿通される挿通支持部３４が形成されている。これら嵌合部３３と挿通支持部３４は、同軸に形成されている。そして、ノズル３１は、嵌合部３３の上端側に位置するようにしてノズル体３２の中途部から突出するように形成されている。   Furthermore, a nozzle body 32 provided with a nozzle 31 for injecting carbon dioxide gas injected from the gas ejection hole 18 is attached to the distal end side of the operation member insertion portion 27. The nozzle body 32 has a cylindrical fitting portion 33 that is fitted to the operation member insertion portion 27 on the base end portion side, and an insertion support portion 34 into which the opening / closing operation member 20 is inserted on the upper end side. Yes. The fitting portion 33 and the insertion support portion 34 are formed coaxially. And the nozzle 31 is formed so that it may protrude from the middle part of the nozzle body 32 so that it may be located in the upper end side of the fitting part 33. FIG.

上述のように形成されたノズル体３２は、嵌合部３３を操作部材挿通部２７に嵌合させて弁箱１１に取り付けられる。このとき、ノズル体３２は、図２及び図３に示すように、ノズル３１の基端部側が操作部材挿通部２７の上端側に臨むように位置決めして操作部材挿通部２７に取り付けられ、ノズル３１は、操作部材挿通部２７に連通した状態となる。   The nozzle body 32 formed as described above is attached to the valve box 11 by fitting the fitting portion 33 to the operation member insertion portion 27. At this time, as shown in FIGS. 2 and 3, the nozzle body 32 is positioned and attached to the operation member insertion portion 27 so that the base end side of the nozzle 31 faces the upper end side of the operation member insertion portion 27. 31 is in a state of communicating with the operation member insertion portion 27.
