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).

Abstract: A compressor system includes a housing with a low pressure first chamber and a high pressure second chamber. A motor in the first chamber has a shaft that passes into the second chamber. A compressor in the housing is operably connected to the motor by the shaft. The second chamber contains an oil sump storing lubricating oil for the compressor. A fluid path through the compressor system includes a first orifice in the housing communicating a suction tube with the first chamber, a first fluid passage communicating the first chamber with the compressor suction port, a second fluid passage communicating the compressor discharge port with the second chamber, and a second orifice in the housing communicating the second chamber with a discharge tube. By the action of the compressor, the fluid in the first chamber is maintained at compressor suction pressure and the fluid in the second chamber is maintained at compressor discharge pressure. Placement of the motor in the low pressure chamber allows operation of the compressor system in environments with high ambient temperatures without adverse effects on the motor performance. Lubricating oil is separated from the compressed fluid with a baffle in the high pressure chamber. Further oil separation can be carried out using a weighted disk secured on the shaft in the high pressure chamber. Fluid discharged from the compressor can be directed onto the rotating weighted disk, which propels oil in the fluid onto the inner wall of the housing. The separated oil drains into the oil sump.
