Abstract
A variable displacement compressor with a variable angle non-rotary wobble plate, having a control valve assembly which includes a pressure detecting unit for detecting a change in a pressure in the compressor crankcase and a single valve mechanism arranged in a communication passageway between the crankcase and the compressor suction chamber and able to control communication between the crankcase and the suction chamber in association with a pressure changing signal from the pressure detecting unit so that the pressure in the crankcase is maintained at a predetermined pressure value.
