Abstract: The hermetically encapsulated refrigerant compressor includes a cylinder, a reciprocating piston arranged in the cylinder and having a reciprocating piston axis, a valve plate comprising a suction valve opening and a discharge valve, a cylinder head on the side of the valve plate facing away from the cylinder, a cylinder head cover which has an outlet for compressed refrigerant, and a sound absorber. On the side of the valve plate facing away from the cylinder, a nozzle is arranged as an inlet for refrigerant to be drawn in, the nozzle having a first end arranged at the suction valve opening and a second end. The nozzle is inclined at a maximum angle of inclination of between ?45° and +45° in relation to the reciprocating piston axis. The sound absorber has a housing with a suction opening into which the second end of the nozzle leads.

Abstract: The invention relates to a hermetically encapsulated refrigerant compressor comprising a housing having a bottom part and a cover, the cover being connectable to the bottom part, an electrical connection piece penetrating the housing and a piston pump which is arranged in the housing and can be electrically connected to a control unit via the connection piece. The cover of the housing has a through opening in which the electrical connection piece is arranged. The housing is configured in such a way that, when the housing is open, the piston pump can be inserted into the cover of the housing and is connectable to the electrical connection piece.
