Claims

[Scope of utility model registration request]

a reversible rotary motor; a valve body driven by the motor;
In the auxiliary air control valve for an internal combustion engine, the valve seat has a metering orifice that is opened and closed by the valve body, and controls the amount of air supplied during engine idling, the auxiliary air control valve for an internal combustion engine having one end attached to the body of the control valve surrounding the shaft of the motor. A fixed return spring is provided, and a return pin is provided on the shaft of the motor, and comes into contact with a movable end of the return spring when the valve opening is equal to or greater than a predetermined value, and transmits the torque generated by the return spring to the shaft of the motor. is provided, and when the control current is no longer supplied to the motor, the return spring and the return pin adjust the valve opening corresponding to the idle speed of the engine before loosening and the steady idle speed after loosening. An auxiliary air control valve for an internal combustion engine, characterized in that the valve opening is reduced to the predetermined value between the corresponding valve opening.
