ABSTRACT:
An electromagnetic actuator for controlling an amount of an intake air for an internal combustion engine employs an elastic member for biasing a valve body toward a valve seat by a predetermined setting force. The repulse of the valve body that is caused when the valve body hits the valve seat is absorbed by the elastic member. Since the elastic member is located behind the valve body, the elastic member of the present invention has no tendency to adhere the valve body on the valve seat.
