Abstract
In a swash plate type variable displacement compressor, a rear housing has a pressure regulation chamber into which a rear end of a drive shaft body, a projection of a second cylinder block, a second sliding bearing, and a rear end of a second support member project. In the compressor, when a drive shaft is rotated, heat is generated in the drive shaft body, the projection, the second sliding bearing, and the second support member to heat the refrigerant gas in the pressure regulation chamber. Accordingly, in the compressor, temperature of the refrigerant gas in the pressure regulation chamber is hard to drop. Therefore, the pressure of the refrigerant gas flowing from the pressure regulation chamber to the pressure control chamber is varied quickly and a movable body is preferably moved with the pressure in the pressure control chamber.
