Abstract

A hermetically encapsulated refrigerant compressor has a hermetically sealed compressor housing, in the interior of which operates a refrigerant-compressing piston-cylinder unit, a suction duct, via which refrigerant is conveyed into the compressor housing, and a pressure duct, via which refrigerant is conveyed out of the compressor housing by the piston-cylinder unit. In order to prevent contact of oil flowing down the compressor housing wall with the suction duct or the pressure duct, a deflection element is on the compressor housing, and in the operating position of the compressor housing the deflection element is above the passage of the suction duct or pressure duct through the compressor housing wall. The heating of the refrigerant is thus prevented and the efficiency of the refrigerant compressor is increased.
