HERMETIC COMPRESSOR
Document Type and Number:
WIPO Patent Application WO2002044562
Kind Code:
A3
Abstract:
A compressor system (10) includes a housing (12) with a low pressure first chamber (14) and a high pressure second chamber (16). A motor (24) in the first chamber (14) has a shaft (30) that passes into the second chamber (16). A compressor (18) in the housing (12) is operably connected to the motor (24) by the shaft (30). The second chamber (16) contains an oil sump (48) storing lubricating oil for the compressor (18). By the action of the compressor (18), the fluid in the first chamber (14) is maintained at compressor suction pressure and the fluid in the second chamber (16) is maintained at compressor discharge pressure. Lubricating oil is separated from the compressed fluid with a baffle (58) in the high pressure chamber (16). Further oil separation can be carried out using a weighted disk (62) secured on the shaft (30) in the high pressure chamber (16).
