) An electric control valve described in Japanese Patent No. 1986-1.96477 is known. As shown in FIG. 3, this control valve has a valve body 40, a valve chamber 42 having a first conduction port [1] and a second conduction port communicating with a valve seat surface 41, and a coil 43 on the outer peripheral surface. A rotor chamber 44 is equipped with a rotor chamber 44, a male threaded pipe 45 is provided at the boundary between the valve chamber 42 and the rotor chamber 44, and a rotor 47 is provided with a female threaded pipe 46 in the center that is screwed into the male threaded pipe 45.
It is configured to include a needle valve 48 that slides within the male threaded pipe 45, opens and closes the valve seat surface 41, and has its base end attached to the center of the rotor 47.

記弁座面４１を開閉する。In this control valve, when the coil 43 is energized, the rotor 47 rotates around the male threaded pipe 45, and as the rotor 47 rotates, the rotor 47 moves in the axial direction, so the needle valve 48 slides, and the needle valve 48 slides. The valve 48 opens and closes the valve seat surface 41.

In order to assist the rotation of the rotor 47, a guide rod 50 having a spiral guide protrusion piece 9 is provided on the other end surface of the rotor chamber 44, while the rotor 47 is guided by a guide protrusion piece 49. A slider 52 is fixed to which is attached a guide pin 51 that moves in the axial direction.

In the structure of the control valve described in Japanese Patent No. 477, the lead angle of the spiral guide protrusion piece portion 49 of the guide rod 50 is thick ( Therefore, the length of this guide rod 50 becomes long, and the needle valve 48
In order to avoid contact between the rotor chamber 44 and the guide rod 50,
tends to increase in axial length.

て騒音が生じるという問題もある。Furthermore, since the rotor 47 is supported in a cantilevered manner by being screwed into the male threaded pipe 45, when the rotor 47 rotates, the rotor 47 makes an oscillating motion using the threaded part with the male threaded pipe as a fulcrum, and the rotor 47 There is also the problem that noise is generated due to contact with the inner surface of the rotor chamber 44.

題もある。Furthermore, when the diameter of the opening of the valve seat surface 41 is increased in order to increase the flow rate, the diameter of the needle valve 48 becomes larger and the diameter of the male threaded pipe 45 also becomes larger. Since the amount of movement in the axial direction of the valve seat surface 41 becomes smaller, there is also a problem that there is a limit to the opening radius of the valve seat surface 41.
本発明の目的は、上記の問題を解決し、小型で、弁座面

面を閉塞する。Therefore, when the rotor is rotating so that the needle valve approaches the valve seat surface of the valve chamber, this rotor rotates integrally with the adjacent rotation regulating plate, and further integrally with the rotation regulating plate that is stopped sequentially. When all rotation regulating plates start rotating together with the rotor, the rotation of the rotor is stopped by a rotation regulating means in which the rotation regulating plates contact the rotor chamber and stop the rotation of the rotor, and the needle valve occlude the surface.

に摺動可能となる。When the coil 16 is energized, the rotor 12 rotates while the shaft 13 is supported by the shaft support 14 of the shaft support member 2 and the shaft support 17 of the rotor chamber 4. Since it is connected to the engagement recess 24, this moving shaft 21 is connected to the rotor 1 on the inner peripheral surface of the shaft support member 2.
Since the moving shaft 21 is screwed and held by the shaft supporting member 2, the moving shaft 21 can be slid in the axial direction.

In this way, the rotation regulating plate 25 sequentially rotates integrally with the rotor 12, and finally, the protruding piece 26 of the rotation regulating plate 25 closest to the closed end of the rotor chamber 4 rotates at the closed end of the rotor chamber 4. Rotation of the rotor 12 is stopped when it comes into contact with a protruding piece 29 formed in the rotor 12. This rotor 1
The moving shaft 21 moves axially toward the valve seat surface 5 according to the amount of rotation of the needle valve 22, and the needle valve 22 closes the valve seat surface 5 while being biased by the coil spring 23.

される。In this state, the protruding piece 28 of the rotor 12, which has started rotating, similarly to when the rotor 12 rotates clockwise,
The rotation regulating plate 25 comes into contact with the other locking edge 27 of the adjacent rotation regulating plate 25, and this rotation regulating plate 25 begins to rotate together with the rotor 12. Furthermore, the protruding piece 2 of this rotating rotation regulating plate 25
6 is a rotation regulating plate 2 adjacent to the closed end side of the rotor chamber 4;
The rotation regulating plate 25 also rotates together with the rotor 12 by being brought into contact with the other locking edge 27 of the rotor 12 . In this way, the rotation regulating plate 25 sequentially rotates integrally with the rotor 12, but finally, the protruding piece N26 of the rotation regulating plate 25 closest to the closed end side of the rotor chamber 4 is formed at the closed end of the rotor chamber 4. The rotation of the rotor 12 stops when it comes into contact with the protruding piece 29 that has been rotated. Since the needle valve 22 retreats from the valve seat surface 5 in the axial direction according to the amount of rotation of the rotor 12, the valve seat surface 5 is opened and the first communication port 6 and the second communication port 8 are communicated with each other. .
このように、上記措成によれば、ローター１２は、軸と

In addition, the needle valve 2 that opens and closes the valve seat ff1i 5
2 is not housed inside the shaft 13 of the rotor 12, so there is no restriction on the opening diameter of the valve seat surface 5 [1 diameter or the diameter of the needle valve 22, and it is small and the valve opening [I has a large diameter and a large flow rate]. Flow control valves can be supplied.

「ｊ径が制限されることもない。According to the present invention, the rotor rotates while the shaft of the rotor is supported by the shaft supporting member and the closed end surface of the rotor chamber, and further, the rotation of the rotor is caused by the needle valve coupled to the shaft in the rotational direction of the rotor. The tip of the needle valve opens and closes the valve seat surface by sliding in the axial direction, so stable rotation of the rotor is obtained, and the opening diameter of the valve seat surface is not limited. .
さらに、過回転防止は、シャフトに回転自在に支持され
