Abstract (en)

[origin: WO2011137474A2] 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. The main body (8) has four side walls (11, 12, 13, 14), which each have a longitudinal extension and a width extension that is shorter than the longitudinal extension, wherein the two side walls (11, 12) having larger areas are opposite each other and are curved in the same direction when viewed in a direction parallel to the longitudinal extension.
