(54) Swash plate type compressor


(57) A swash plate type compressor has a housing assembly (1,3,5), a drive shaft (7), a swash plate (29), a piston (21), a motion converter (35), a bleed passage (39), and an oil separator (43). The housing assembly includes a cylinder bore (1A), a suction chamber (11), a discharge chamber (13), and a crank chamber (15). The drive shaft is rotatably supported by the housing assembly, and extends through the crank chamber. The bleed passage communicates between the crank chamber and the suction chamber. The oil separator is disposed in the housing assembly. The oil separator separates no or less amount of lubricating oil from the refrigerant gas in the increased rotational speed of the drive shaft than that in the decreased rotational speed of the drive shaft. The refrigerant gas passed through the oil separator is introduced into the suction chamber, and the separated lubricating oil is returned to the crank chamber.
