  • Compressor utilizing shell with low pressure side motor and high pressure side oil sump
    Patent number: 6499971
    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.
