  • Publication number: 20130330214
    Abstract: The invention relates to a discharge silencer (6) for a hermetically encapsulated refrigerant compressor (1), which comprises a piston/cylinder unit (4) that compresses a refrigerant and has a compression chamber (3) and which is enclosed by a hermetically sealed compressor housing (2), wherein the compression chamber (3) is supplied with refrigerant coming from an evaporator through a suction silencer (5) and discharges refrigerant compressed by the piston/cylinder unit (4) into a pressure line (7a, b) through the discharge silencer (6). According to the invention, the discharge silencer (6) comprises a main body (8), on which an inlet flange (9) for the refrigerant coming from the piston/cylinder unit (4) is arranged, and an outlet channel (10), through which the refrigerant can be led into a pressure line (7a, b) that supplies a condenser with compressed refrigerant.
