いる。 A lower cover 5 is provided on the upper part of the valve body 1 with the male screw tube 4 in the center, and a closed case 6 of the stepping motor section M is fixed onto the lower cover 5. A stator 8 having a built-in coil 7 is provided on the outer periphery of the case 6. A rotor 9 is rotatably supported within the case 6 by the male threaded tube 4. The rotor 9 is constructed by fitting a cylindrical permanent magnet 11 onto the outer periphery of a support tube 10, and then expanding the upper edge 10a onto the permanent magnet 11 to integrate the two. A female threaded tube 12 is fitted and fixed to the lower inside of the male threaded tube 4 and is screwed onto the male threaded tube 4 so as to be rotatable and movable in the axial direction.

おいて巻装されている。 A connecting wall 10 is provided in the axially intermediate portion of the support tube 10.
b is formed, and after the small diameter portion 3a of the needle valve 3 is inserted into the hole 10c, it is fixed with an E ring 13. A compression coil spring 14 is wound around the small diameter portion 3a of the needle valve 3 between the stepped portion 3b and the connecting wall 10b.

係合している。 In the upper part of the rotor 9, a spiral guide ring 16 is wound around a shaft 15 fixed to the case 6, and a slider 17 is engaged with the spiral guide ring 16 so as to be rotatable and vertically movable. The outer end of the slider 17 engages with a locking rod 18 erected on the rotor 9.

移動を停止する。 In the above configuration, when the coil 7 of the stator 8 is energized, the rotor 9 rotates, and in accordance with the rotation of the rotor 9, the slider 17 moves up and down along the spiral guide ring 16 and collides with the upper and lower ends 16a and 16b thereof. At this position, rotation of the rotor 9 and movement of the needle valve 3 are stopped.
ニードル弁３が弁座２ａを閉止した際にはコイ
ルバネ１４が若干圧縮されるように構成されてい
る。 The coil spring 14 is configured to be slightly compressed when the needle valve 3 closes the valve seat 2a.
本発明は上記した如くに成るものであるから、

作動ができる特長を有する。 Since the present invention is constructed as described above,
By integrally incorporating the needle valve inside the motor, it is possible to downsize the entire valve device, and the rotor of the motor can be supported on a cantilever, simplifying the configuration. Since the point of application of the driving force and the load from the needle valve is in the nearby axially intermediate part, the influence of vibrations due to the rotation of the motor itself and vibrations due to the fluid in the valve part is minimized, resulting in low-noise operation. It has the characteristics of smooth operation and stable operation with small torque.
