Abstract
In a swash plate type compressor, refrigerant in a discharge pressure region is introduced into a crank chamber through a supply passage while the refrigerant in the crank chamber is drawn out to a suction pressure region through a bleed passage for controlling pressure in the crank chamber, whereby inclination angle of a swash plate is changed. A heat-generating sliding portion is provided in the crank chamber. The supply passage includes a communication port that communicates with the crank chamber and a first throttle portion for throttling the refrigerant. At least parts of the supply passage and the bleed passage are formed in a drive shaft. A part of the bleed passage formed in the drive shaft is located between a part of the supply passage formed in the drive shaft and an outer peripheral surface of the drive shaft.
