Title:
COMPRESSOR
Document Type and Number:
WIPO Patent Application WO/2007/004359
Kind Code:
A1
Abstract:
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 air supply passage (44) supplying the working fluid to the pressure
control valve (34) is formed in a rear housing (5), the air introducing port (45)
of the air 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 air supply passage (46) after being fed from the air introducing
port (45) to the pressure control valve (34) through the air 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.
