COMPRESSOR

摘要

A compressor capable of avoiding the instability of the control of a pressure in a crankcase by feeding a working fluid with a low oil mixing ratio to a pressure control valve to reduce the adhesion of oil to the valve body of the pressure control valve. When an supply passage (44) supplying the working fluid to the pressure control valve (34) is formed in a rear housing (5), the introducing port (45) of the supply passage (44) is opened to the downstream side of the oil separating tube (39) of an oil separator (36). Since the working fluid from which the oil is separated and removed from the oil separator (36) is returned to the crankcase (8) through an supply passage (46) after being fed from the introducing port (45) to the pressure control valve (34) through the supply passage (44), the possibility of the adhesion of the oil mixed in the working fluid to the pressure control valve (34) can be reduced.
