Abstract: In order to further improve the sound damping in a refrigerant compressor comprising a common housing, a screw-type compressor in a common housing has a compressor housing that is formed as part of the common housing with a first sound absorber unit which is arranged in the common housing. The first sound absorber unit is arranged adjacent a housing window, and the sound absorber unit comprises at least one chamber which is located between an inlet opening and an outlet opening and which widens out relative to the inlet opening and to the outlet opening in a direction transverse to a direction of flow.

Abstract: In order to further improve the sound damping in a refrigerant compressor comprising a common housing, a screw-type compressor which is provided in the common housing and has a compressor housing that is formed as part of the common housing and in which there is arranged at least one screw rotor boring, at least one screw rotor that is arranged in the screw rotor boring such as to be rotatable about a rotational axis, a suction-side bearing unit for the screw rotor that is arranged on the compressor housing, at least one pressure-side bearing unit for the screw rotor that is arranged on the compressor housing and a housing window for compressed refrigerant that is provided on the compressor housing, and a first sound absorber unit which is arranged in the common housing, it is proposed that the first sound absorber unit be arranged adjacent the housing window, and that the sound absorber unit comprise at least one chamber which is located between an inlet opening and an outlet opening and which widens out rel
