Abstract
A variable displacement swash plate type compressor includes a control valve having a valve body and a solenoid portion A refrigerant circuit has first and second pressure monitoring points. A load based on a point-to-point differential pressure, which is a differential pressure between the pressure at the first and second pressure monitoring points, is applied to the valve body. At least one of a load based on a DS differential pressure, which is a differential pressure between the pressure in a discharge pressure zone and the pressure in a suction pressure zone, and a load based on a CS differential pressure, which is a differential pressure between the pressure in the control pressure chamber and the pressure in the suction pressure zone, acts on the valve body in the same direction as the direction of the load applied to the valve body based on the point-to-point differential pressure.
