Abstract

A compact, low-cost capacity control valve 30 for a variable displacement compressor 1 is an integrated structure of first and at least second control valves 30A, 30B. The first control valve 30A, placed on a discharge passageway, functions as a variable orifice whose cross-sectional area can be set as desired by varying the power of a solenoid unit 30C. Part of refrigerant discharged at pressure PdH is supplied to the crank chamber 15, in which the pressure is Pc. The second control valve 30B controls the flow to the crank chamber 15 such that the differential pressure between upstream and downstream pressures PdH, PdL will be regulated at a specified level. This allows to reduce the size of the solenoid unit 30C because the first control valve 30A does not need a large force to yield a small differential pressure as required for the control operation.
