Abstract

See full text

A screw expander system has a condenser positioned for receiving a mixture of oil and operating medium from a screw expander. A pump pressure-feeds the mixture from the condenser to an evaporator where the operating medium is evaporated. An oil separating tank separates the mixture from the evaporator into the gaseous operating medium and the oil, and the operating medium is returned to the screw expander via a throttle mechanism. The oil can thereby be supplied to the screw expander without providing a separate oil pump, as a result of which the screw expander system is compact.
