ABSTRACT:
The invention concerns a refrigerant compressor (1), particularly a semi-hermetic refrigerant compressor, with a housing (2), having in its bottom part (3) an oil sump (4), a compressor block (5) having at least one cylinder (6), in which a piston (7) is arranged, a crankshaft (11), which is supported in the compressor block (5) and in driving connection with the piston (7), and an oil pump arrangement (27), which is at least partly submerged in the oil sump. Also with varying speeds, good oil lubrication must be ensured. For this purpose, the crankshaft (11) has at its lower end a diameter extension (19), through which an oil channel (35) extends eccentrically to the crankshaft axis (36), said channel (35) connecting the oil pump arrangement (27) to a closed oil pressure chamber (21) between the crankshaft (11) and the compressor block (5), said chamber (21) being connected to the inside (37) of the housing (2) via a vent path (40, 41).
