Variable displacement compressor
Abstract:
A displacement control valve for a variable displacement compressor includes a valve element. The valve element has a discharge pressure receiving surface which receives pressure in a discharge chamber and a suction pressure receiving surface which receives pressure in a suction pressure section acting in a direction opposite to the direction that the pressure in the discharge chamber acts on the discharge pressure receiving surface. The displacement control valve also includes a solenoid generating generates an electromagnetic force acting on the valve element, and a urging means urging on urges the valve element in a valve closing direction to hold the valve element in a valve closing position when the generated electromagnetic force generated by the solenoid is not acting on the valve element.
