可変揺動斜板型圧縮機。[Claims for Utility Model Registration] A drive shaft rotatably supported in the crank chamber, a swash plate pivotally supported on the drive shaft, and a thrust washer connected to the swash plate in a rotationally restricted state. A rocking plate that is moored and makes the piston reciprocate within the bore of the cylinder according to the inclination angle, and the stroke of the piston is changed according to the differential pressure between the crank chamber pressure and the suction pressure, thereby causing the rocking. In a variable capacity oscillating swash plate compressor in which the compression capacity is controlled by changing the inclination angle of the plate, there is provided an air supply passage that supplies discharge pressure from a discharge chamber to the crank chamber according to the cooling load; an air bleed passage that supplies the crank chamber pressure from the chamber to the suction chamber, the air supply passage and the air bleed passage,
a nozzle that opens at a position facing the thrust washer when the rocking plate approaches the cylinder at a minimum angle of inclination, and that protrudes toward the thrust washer in at least one of the air supply passage and the air bleed passage; A variable capacity oscillating swash plate compressor characterized by comprising:
