The amount of air in the engine does not need to wastefully increase the rotation of the engine, and the engine warm-up operation is good. [Inventive content] (Problems to be solved by the invention) According to the conventional suction control device, the engine is included When the throttle valve is opened at the low opening degree, the negative pressure generated inside the intake passage of the downstream side of the throttle = 53 is applied to the valve body through the auxiliary air outflow hole 57; The control valve body v applies a negative pressure 'corresponding to the area of the valve body pilot hole 55' to force the valve body V to pull downward. Here, the locomotive that controls the valve body v by using the speed adjuster w is used. In the case of the starter, the thermal expansion and contraction material is sealed inside the paraffin member, and a large pressing force can be generated. Therefore, the lifting force of the pull-down force f 94135145 9 1312834 can be set as the elastic force of the spring 67. Therefore, the detachable type can be eliminated. On the other hand, in the idle speed control using the Xiang motor speeder cold > / valve body V inlet operation, it is necessary to overcome the large pulling force of the pull-down force F by a motor such as Γ 2, thereby making the motor Large size The overall size of the flow body is increased, and the power consumption f of the motor Ma is increased, and the manufacturing cost of the motor is increased.
