ABSTRACT:
The object is to provide a capacity control valve for a variable displacement compressor, which is not adversely affected by pressure from a pressure-regulating chamber. The cross-sectional area of a valve hole of a high pressure-side valve seat for introducing discharge pressure Pd of a variable displacement compressor into a pressure-regulating chamber is A, the cross-sectional area of a valve hole of a low pressure-side valve seat for introducing pressure Pc1(=Pc2) of the pressure-regulating chamber into a suction chamber is B, and the average cross-sectional area of a refrigerant passage assumed when a low-pressure valve element is open during most of control time of actual operation is b. A and B are set to A<B to make the effective pressure receiving area (≅A) of the high pressure-side valve and the effective pressure receiving area (≅B−b) of the low pressure-side valve approximately equal.
