Abstract

A scroll type hermetic compressor is disclosed which incorporates an improved disc type check valve in the discharge conduit exiting from the compressor shell. The check valve operates to prevent return of high pressure refrigerant which may cause reverse movement of the orbiting scroll upon shut down of the compressor.
