Title:
ROTARY COMPRESSOR AND REFRIGERATING APPARATUS
Document Type and Number:
WIPO Patent Application WO/1996/013666
Kind Code:
A1
Abstract:
A blade (8), which divides a cylinder chamber (41) into a compression chamber (X) and a suction chamber (Y), is integrally secured to roller (7), which is fitted onto an eccentric portion (22) of a drive shaft (21), to extend radially outwardly from the roller (7). A tip end of an extension of the blade (8) is received in a receiving groove (11a) of a support (11) which is rotatably supported on a stationary member (4). CFC substitute refrigerant is used as a working fluid in the cylinder chamber (41), and an oil corresponding to the CFC substitute refrigerant is used as a lubricating oil for a compressor CP. Thus degradation of the oil in the compressor is prevented while the CFC substitute is used.
