Abstract: The invention relates to a refrigerant compressor, comprising a compressor housing (1) that can be hermetically capsuled, and a compressor-motor unit (4) arranged in the housing interior (3) of the compressor housing (1), which is elastically mounted on an inner side of the compressor housing (1) by way of at least one spring element (5), wherein at least one damping element (9) made of an elastomer is provided, in order to damp the transmission of vibrations caused by the compressor-motor unit (4) to the compressor housing (1). The at least one damping element (9) is made of an elastomer that is softer compared to polyamide (PA), polybutylene terephthalate (PBT), ethylene chlorotrifluoroethylene (ECTFE).
