題を解決するものである。In the conventional idle rotation control device having the servo mechanism, the air flow metering valve is fixed to the diaphragm mechanism component by resin by outsert molding. Therefore, the assembly process is complicated and the cost is high. In addition, the simple press-fitting method has a problem that the strength of the valve body coming out is low. Claim 1 or 2 solves this problem.

解決する。In order to solve the above-mentioned problems, according to the present invention, an air flow metering valve provided in a part of a diaphragm mechanism member can be assembled in a final step. The problem is solved by having a structure for press-fitting and fixing and by providing a groove in the shaft to increase the drop load of the valve body.

It can be assembled in any step of the diaphragm mechanism component assembly process. Therefore, it is possible to exclude the molding method, the assembly process, etc., which are conventionally restrained, and the reliability can be ensured because the pull-out load is increased by forming the groove in the shaft.

の上下流をバイパスする通路の通気量を制御する。The diaphragm mechanism 1 includes two valves 5 and 6 which sandwich the inner circumference of a valve 2, a hollow shaft 3, a diaphragm 4 and a diaphragm 4, a leak orifice 7 provided on the plate 5, and a control provided on the shaft 3. It consists of valve 8. The plunger part includes a plunger 9, a plunger shaft 10, a control valve seat 11, a valve stopper 12 that stops the control valve seat, and a spring 1 that presses the control valve seat.
It consists of three. The plunger portion moves in the solenoid 14 and has a function of uniquely determining the position of the plunger portion with respect to the electric input by the balance between the magnetic force generated in response to the electric input of the solenoid 14 and the force of the springs 15 and 19. The diaphragm mechanism 1 is placed in the body 16, and the outer periphery of the diaphragm 4 is fixed by being sandwiched between the solenoid 14 and the body 16, so that the diaphragm mechanism 1 can move left and right in the figure within the range allowed by the body. The relative position between the seat 17 provided on the inner diameter of 16 and the valve 2 controls the amount of ventilation of the passage that bypasses the upstream and downstream of the engine throttle valve.

た場合の実施例である。The operation is based on the control valve seat 11 of the plunger section.
Is separated from the control valve 8, the pressure in the diaphragm chamber 18 formed between the solenoid 14 and the diaphragm 4 is reduced, a force on the left side in the drawing is generated in the diaphragm 4, and the diaphragm mechanism moves to the left side in the drawing. When the control valve seat 11 closes the control valve 8, the atmospheric pressure is introduced from the leak orifice 7, the pressure in the diaphragm chamber 18 rises, the differential pressure across the diaphragm 4 disappears, and the differential pressure across the valve 2 causes the diaphragm mechanism to operate. Move to the right in the figure. The position of the diaphragm mechanism 1 follows the position of the control valve seat 11 by the balance of these opposing forces. In the idle rotation device of this structure, the valve 2 is formed of resin and press-fitted and fixed.

る。FIG. 2 shows an enlarged view of an example in which a groove is provided in the press-fitting portion of the shaft 3 into which the valve 2 is press-fitted. After the press-fitting, the valve 2 has internal stress due to press-fitting, but this internal stress causes deformation of the valve 2 facing the groove portion of the shaft 3, and this deformation increases the pull-out load of the valve 2 and pulls out the valve 2. It is possible to obtain an improvement in reliability.
