Claims

[Claims for Utility Model Registration] The crankshaft is equipped with a suction chamber, a discharge chamber, and a crank chamber, and a swash plate is provided in the crank chamber to convert rotation of a drive shaft into reciprocating motion of a piston housed in a cylinder bore. In a variable displacement compressor in which the stroke of the piston is changed by changing the inclination angle of the swash plate according to the differential pressure between the chamber pressure and the suction pressure to control the compression capacity, the suction chamber and the discharge chamber are A variable capacity compressor that is provided with a constriction part in which the flow path area of refrigerant gas is temporarily reduced between the suction hole of the suction chamber and the refrigerant gas suction port of the compressor in the formed housing.
