ABSTRACT:
A motor driven refrigeration compressor having a cylinder head and base of laminated construction. The laminations are formed from flat sheet stock with apertures which define inlet and outlet ports and passages for refrigerant flow. The base is bell shaped and the enclosed end contains integral inlet ports and passages which direct refrigerant past the motor and into the compressor. The base walls contain integral outlet passages which convey the refrigerant from the compressor to an outlet tube in communication with a condenser. Both the inlet and outlet passages contain noise reducing cavities which decrease the effect of the pulsations inherent in a piston-type compressor.
