動抵抗が大きくなるという問題があつた。 However, in such a conventional idle speed control valve, since the valve body 4 is configured to slide within the bearings 2 and 3 that support the valve body 4, the sliding friction resistance of the valve body 4 is large, and the solenoid coil This was a factor in the occurrence of hysteresis in the bypass air flow rate characteristics with respect to the amount of current applied to the pump. For this reason, the control accuracy of the bypass air flow rate has deteriorated. Also, bearing 2,
There was a problem in that the sliding resistance further increased due to wear of the parts 2 or dust entering the bearing part.

転数制御弁を提供することを目的とする。 The present invention was developed in view of these conventional problems, and by supporting the rod-shaped valve body with a leaf spring that can deform only in the direction of the valve axis, the valve body can be moved without using the conventional bearing part. It is an object of the present invention to provide an idle rotation speed control valve which reduces sliding frictional resistance generated during operation and prevents hysteresis from occurring in bypass air flow characteristics.
以下、本考案を第２図及び第３図に示す一実施

続してある。 In the figure, a rod-shaped valve body 20 is supported at both ends by leaf springs 21 and 22, which will be described later, respectively, so as to be concentric with the valve seat 10. That is, at one end on the solenoid coil 7 side, the solenoid case 5 mounting flange 14 and the valve body case 1
One end of the valve body 20 and the plunger 6 are screwed together through a hole 21a in the center of a leaf spring 21 held between the valve body 20 and the plunger 6. At the other end, the valve body 2 is inserted through a hole 22a in the center of a leaf spring 22 held between the valve body case 1 and another valve body case 1A that is separate from the case 1.
0 and a retainer 23 of the spring 22 are screwed together.

いる。 As shown in FIG. 3, the leaf springs 21 and 22 have grooves 21b of an appropriate shape around the center portions so that the center portions where the holes 21a and 22a are formed are easily deformed in the vertical direction in the figure. It is stamped and formed.

スをなくせ、もつて流量制御精度が向上する。 According to the idle speed control valve having such a configuration,
Since the valve body 20 is supported only by the leaf springs 21 and 22 and has no sliding parts, even if the valve body 20 is moved in the valve axis direction together with the plunger 6 by changing the amount of current applied to the solenoid coil 7,
Unlike the conventional case, sliding frictional resistance is not generated when the valve body 20 moves. For this reason, solenoid coil 7
The amount of movement of the valve body 20 with respect to the amount of current applied to is constant,
This eliminates hysteresis between the amount of current applied and the fluid flow rate, thereby improving flow control accuracy.

上し、アイドル回転数制御精度も向上する。 As explained above, in the present invention, the valve body is supported by a leaf spring that can be deformed only in the direction of the valve shaft, so there is almost no frictional resistance when moving the valve body, and the valve body corresponds to the amount of current applied to the solenoid coil. The position is constant and hysteresis between the amount of current and fluid flow rate can be eliminated. Therefore, the flow rate control accuracy of the control valve is improved, and the idle rotation speed control accuracy is also improved.
