内燃機関のＥＧＲ制御弁。 EGR consists of a valve body that opens and closes the EGR passage of an internal combustion engine, and an actuator that drives this valve body.
The control valve is characterized by being equipped with an air cylinder that holds the valve body in a closed position using supplied operating pressure when EGR is stopped, and a three-way solenoid valve that selectively supplies operating pressure and atmospheric pressure to this cylinder. EGR control valve for internal combustion engine.
