Title: Compressor with internal accumulator for use in split compressor

Abstract: A rotary compressor having a housing with a motor and an internal accumulator located on the low pressure side and an oil sump located on the high pressure side. A sealing means positioned within the housing defines a first chamber and a second chamber. The sealing means substantially maintains the pressure differential between the chambers by segregating high pressure fluid in the second chamber from low pressure fluid in the first chamber. The fluid entering the housing is separated into a gas portion and a liquid portion, the liquid portion being directed downward toward the motor to provide cooling for the motor while the gas portion is directed to a compressor portion. The liquid portion collects about the motor above the sealing means. An orifice or aperture through the sealing means allows liquid collected above the sealing means to be reintroduced into the compressor suction inlet and metered into the refrigerant gas in a controlled fashion and resupply the sump with lubricant.
