More Information
Summary:Provided is a control valve that hardly generates noise from vibration applied thereto, while achieving compactization and power consumption saving of the valve. The valve is incorporated in a coolant circulatory passageway for circulating coolant between an engine and a heat exchanger via a pump. The valve includes a main body having a coolant channel and a valve seat, a valve body movable between a position away from the valve seat and a position in contact with the valve seat, and a solenoid configured to cause the valve body to be adhered to the valve seat with a magnetic force generated in response to supply of electric power thereto. The control valve is configured such that the power supply to the solenoid is started when an ignition key of the engine is under its ON state and the pump is stopped.
