ABSTRACT:
A variable displacement compressor controls a discharge displacement by changing an inclination of a swash plate (5) depending on a pressure differential between a crank chamber (3) and a suction chamber (13) thereby to change a piston stroke. A first communication passage (18) establishes communication between a discharge chamber (14) and the crank chamber. A pressure control valve (19) opens and closes the first communication passage. On the other hand, a second communication passage (20) establishes communication between the crank chamber and the suction chamber. A valve member (21) is disposed in the second communication passage and fully closes the second communication passage due to a biasing force of a spring when a pressure differential between the discharge chamber and the suction chamber becomes not greater than a given value.
