Abstract
The disclosed invention provides an unmodified scroll compressor with enhanced oil management system that enables the compressor system to compress helium. The compressor system includes a standard scroll compressor, oil separator, and an adsorber. The compressor includes a housing containing an orbiting scroll and a stationary scroll, a motor, and an oil sump in a bottom of the housing. The stationary scroll has one or more injection ports, and the housing contains a single discharge port, a return port, and a single injection port connected to the injection ports of the stationary scroll. The oil separator receives a mixture of helium and oil from the discharge port. The compressor system further includes a line bringing a first fraction of oil from the oil separator to the injection port, one or more lines bringing a second fraction of oil to the return port along with helium. The adsorber retains a third fraction of oil.
