Abstract
A variable displacement compressor including a drive shaft through which a gas passage extends between front and rear ends of the drive shaft. The gas passage is connected to a suction chamber at the rear end of the drive shaft. The drive shaft includes a first gas inlet passage, which connects the gas passage to a crank chamber through a lip seal, an oil chamber, and a thrust bearing, and a second gas inlet passage, which connects the gas passage to a central portion of the crank chamber. The drive shaft further includes a sleeve movable along the drive shaft as a swash plate inclines to adjust an open amount of the second gas inlet passage in accordance with the inclination angle of the swash plate, that is, the displacement of the compressor.
