Abstract
A swash plate is arranged to tilt between a maximum inclining angle and a minimum inclining angle based on differential pressure between a crank chamber and a suction chamber. At least one single-headed piston, that is coupled to the swash plate, is disposed in an associated cylinder bore and reciprocates at a stroke according to the inclining angle of the swash plate to compress refrigerant gas introduced to the cylinder bore from an external refrigerant circuit via the suction chamber. A pressure supply passage connects a discharge chamber with the crank chamber to supply the refrigerant gas from the discharge chamber into the crank chamber so as to increase the pressure in the crank chamber and a flow passage which allows flow of the refrigerant gas from the crank chamber to the suction chamber. An introducing passage introduces the refrigerant gas with low temperature from the external refrigerant circuit to substantially equalize the pressures in the crank chamber and the suction chamber. Movable elements selectively open and close the introducing passage in association with the maximum inclining angle and minimum inclining angle of the swash plate.
