REFRIGERANT COMPRESSOR

The invention relates to a refrigerant compressor, comprising: a preferably hermetically sealable compressor housing; an electric drive unit, comprising a rotor (4) and a stator (3); a crankshaft (1),which is connected to the rotor (4) for conjoint rotation and which has a longitudinal axis (2); a piston-cylinder unit, which can be driven by the crankshaft (1); wherein the electric drive unit isdesigned as an external rotor motor and the rotor (4) has a carrier element (12) extending outward radially with respect to the longitudinal axis (2) at least in some sections and the carrier element(12) is connected to the crankshaft (1) for conjoint rotation. According to the invention, in order to enable an increased delivery rate of lubricant from a lubricant sump together with preferably lowor reduced height of the compressor, a sleeve-shaped lubricant receiver (8) for centrifugally conveying lubricant from a lubricant sump formed in a bottom region of the compressor housing toward thepiston-cylinder unit is provi
