Abstract (en)

[origin: WO2007135152A1] The invention relates to a hermetically encapsulated refrigerant compressor which has a hermetically sealed compressor housing (1), in the interior of which operates a refrigerant-compressing piston-cylinder unit and is provided a suction duct (2), via which refrigerant is conveyed into the compressor housing (1), and is provided a pressure duct (3), via which refrigerant is conveyed out of the compressor housing (1) by the piston-cylinder unit. In order to prevent contact of the oil (4) which flows down the compressor housing wall with the suction duct (2) and with the pressure duct (3), it is provided according to the invention that, in the operating position of the compressor housing (1), deflecting means are provided on the compressor housing wall above the passage of the suction duct (2) and pressure duct (3) through said compressor housing wall. In this way, warming of the refrigerant is avoided, and the efficiency of the refrigerant compressor is increased.
