従来、圧力流体を噴出する流体吹出しノズルは、例えば水中の洗浄作業において、高能率、高効率を上げるための水中ノズルが公知となっている。
上記公知技術は、水中において高圧液体を噴出すべきノズルを包囲しかつこのノズルからの液体の噴出方向に開口するデフューザ内に大気に連通する空気管を接続し、もって前記ノズルからの液体の噴射による負圧発生によって前記空気管を介してデフューザ内に空気を吸い込み、その気泡と共に液体を水中に噴出させるようにした水中ノズルを構成するものである（特許文献１を参照）。
しかし、上記水中ノズルは、前記ノズルと前記デフューザとの位置関係が固定であり、前記ノズルを軸方向前後に移動できないと共に、前記ノズルの交換が不可能であった。
そのため、噴出流体の速度調整ができないと共に、各種の用途に合わせたノズルの交換が自由にできなかった。
そこで、本出願人は、ノズルを軸方向前後に移動して噴出流体の速度調整ができると共に、各種の用途に合わせたノズルの交換が可能である流体増速安定装置を発明し、特願２００２−２９３３７０号として出願した。 2. Description of the Related Art Conventionally, as a fluid blowing nozzle that ejects a pressure fluid, for example, an underwater nozzle for increasing efficiency and efficiency is known in an underwater cleaning operation.
In the above-mentioned known technique, an air pipe communicating with the atmosphere is connected to a diffuser that surrounds a nozzle to which a high-pressure liquid is to be ejected in water and opens in a direction of ejecting the liquid from the nozzle. The underwater nozzle is configured such that air is sucked into the diffuser through the air pipe by the generation of negative pressure due to the above, and the liquid is ejected into the water together with the bubbles (see Patent Document 1).
However, in the submerged nozzle, the positional relationship between the nozzle and the diffuser is fixed, the nozzle cannot be moved back and forth in the axial direction, and the nozzle cannot be replaced.
For this reason, the speed of the ejected fluid cannot be adjusted, and the nozzle can not be freely replaced according to various applications.
Therefore, the present inventor invented a fluid acceleration stabilizing device that can adjust the speed of the ejected fluid by moving the nozzle back and forth in the axial direction, and can replace the nozzle according to various applications. Filed as -293370.

以下に、本発明の吸排一体装置の作用を図面に基づいて説明する。
図１に示す吸排一体装置において、前記ノズル外筒１を閉塞している接続部９の蓋体中央孔１５に螺合している第１ノズル嘴２を右回転又は左回転させ、この右回転又は左回転により第１デフューザ１１と第１ノズル嘴２先端と距離間隔が調節され、この距離間隔の調節により圧力流体の増速効果が変化する。
また、用途に応じて前記第１ノズル嘴２を交換可能とし、それに応じて前記接続部９も交換可能とする。
圧力流体の増速効果のために間隔調節が終わったら、流体供給源（図示せず）に連結する圧力流体入口１９、２０から圧力流体が供給されて前記第１ノズル嘴２及び第２ノズル嘴７から圧力流体が噴出される。 Below, the effect | action of the intake / exhaust integrated apparatus of this invention is demonstrated based on drawing.
In the intake / exhaust integrated device shown in FIG. 1, the first nozzle rod 2 screwed into the lid central hole 15 of the connecting portion 9 closing the nozzle outer cylinder 1 is rotated clockwise or counterclockwise, and this clockwise rotation is performed. Alternatively, the distance between the first diffuser 11 and the tip of the first nozzle rod 2 is adjusted by the left rotation, and the effect of increasing the pressure fluid changes by adjusting the distance.
In addition, the first nozzle rod 2 can be replaced according to the application, and the connecting portion 9 can also be replaced accordingly.
When the interval adjustment is completed due to the speed increasing effect of the pressure fluid, pressure fluid is supplied from pressure fluid inlets 19 and 20 connected to a fluid supply source (not shown), and the first nozzle rod 2 and the second nozzle rod 2 are supplied. Pressure fluid is ejected from 7.

前記圧力流体入口１９からの圧力流体は、前記第１ノズル嘴２の第１オリフィス出口１３から第１ノズル孔１０に向かって噴射され、この噴射により、第１ノズル室１２の空気が誘引される。
前記第１ノズル室１２の空気は、第１ノズル孔１０内の圧力流体を囲むようにして圧力流体と一緒に外気に噴射されると共に、前記第１ノズル室１２には負圧が発生するので、接続部９の流体吸引孔１８から外気が導入される。
また、前記第１デフューザ１１と前記第１ノズル嘴２先端との距離間隔の調節を手動で行うようにしたが、これを自動的に制御機器で前後移動できるように構成し、圧力流体の増速効果を自動的に変化させることも可能である。
このように構成することにより、第１ノズル嘴２を制御機器で前後移動させることで前記第１デフューザ１１と第１ノズル嘴２先端との距離間隔が調節され、前記第１ノズル室１２の負圧を自動的に調節することができる。 Pressure fluid from the pressure fluid inlet 19, from said first first orifice outlet 13 of the nozzle beak 2 is injected toward the first nozzle hole 10, by this injection, the air in the first nozzle chamber 12 is attracted .
The air in the first nozzle chamber 12 is injected into the outside air together with the pressure fluid so as to surround the pressure fluid in the first nozzle hole 10, and a negative pressure is generated in the first nozzle chamber 12. Outside air is introduced from the fluid suction hole 18 of the section 9.
Further, the distance between the first diffuser 11 and the tip of the first nozzle rod 2 is manually adjusted. However, the distance between the first diffuser 11 and the first nozzle rod 2 can be automatically moved back and forth by a control device to increase the pressure fluid. It is also possible to change the speed effect automatically.
With this configuration, the distance between the first diffuser 11 and the tip of the first nozzle rod 2 is adjusted by moving the first nozzle rod 2 back and forth with a control device, and the negative displacement of the first nozzle chamber 12 is adjusted. The pressure can be adjusted automatically.

前記圧力流体入口２０からの圧力流体は、前記第２ノズル嘴７の先端からノズル内筒６に向かって噴射され、この噴射により、第２ノズル室１２’に接続された流体吸込み口２１の流体が誘引され、前記流体吸込み口２１からの流体はノズル内筒６内の圧力流体を囲むようにして圧力流体と一緒に外気に噴射される。
したがって、流体吹出しノズル８からの流体吹出しが行われる一方、流体吸引ノズル３では流体吸引が行われる。
なお、空気中での説明を行ったが、水中でも同様に行うことができる。 The pressure fluid from the pressure fluid inlet 20 is ejected from the tip of the second nozzle rod 7 toward the nozzle inner cylinder 6, and by this ejection, the fluid in the fluid suction port 21 connected to the second nozzle chamber 12 ′. The fluid from the fluid suction port 21 is injected into the outside air together with the pressure fluid so as to surround the pressure fluid in the nozzle inner cylinder 6.
Therefore, while fluid is ejected from the fluid ejection nozzle 8, fluid suction is performed at the fluid suction nozzle 3.
In addition, although demonstrated in the air, it can carry out similarly in water.

次に、本発明の吸排一体装置の他の実施例を図面に基づいて以下に説明する。
