Abstract: A two stage hermetic compressor which uses carbon dioxide as the working fluid. A pair of modules individually housing compression mechanisms are located at opposite ends of a module housing an electric motor. The modules are secured to one another when the compressor is assembled. Suction pressure carbon dioxide gas is compressed in the first compression mechanism to an intermediate pressure which is introduced into an electric motor module compartment. The intermediate pressure gas enters the second compression mechanism module through a suction port. A conical baffle is affixed to the upper compression mechanism module to protect the suction port from direct suction of oil and to separate oil entrained in the gas therefrom. The intermediate refrigerant gas is compressed to a discharge pressure and is discharged into a compartment defined in the second compression mechanism module. The discharge pressure gas is then exhausted to the refrigeration system.
