Abstract (en)
[origin: WO2006067218A1] The invention relates to a hermetically enclosed refrigerant compressor having a hermetically tight compressor housing (1) inside of which a piston/cylinder unit that compresses a refrigerant operates with a suction valve having a suction opening located in a valve plate of said unit. A suction sound damper (16) having a filling volume (20) is provided on the cylinder head (15) of the piston/cylinder unit and refrigerant flows to the suction valve of the piston/cylinder unit via this suction sound damper. To this end, the suction sound damper (16) has an entry cross-section (18) via which refrigerant flows into the suction sound damper (16), and a compensation volume (21) is provided, which is connected to the suction sound damper (16) and to the interior of the compressor housing (1), and inside of which refrigerant oscillates. The compensation volume (21) equals 0.5 to 3 times the displacement of the piston of the piston/cylinder unit.
