| 摘要 |
The invention concerns a refrigerant compressor (1), in particular a semi-hermetic refrigerant compressor, with a compressor block (5) comprising several cylinders arranged in a star shape, a motor, whose rotor is unrotatably connected to a crankshaft (11) that comprises a crank pin (22) and is supported in a bearing (13) in the compressor block (5), and a piston in each cylinder, each piston being connected via a connecting rod (23) to the crank pin (22), the connecting rod (23) comprising a bearing pad (24) that rests on the crank pin (22), the bearing pads (24) of all connecting rods (23) being held on the crank pin (22) by means of a ring arrangement (25). It is endeavored to keep the load on the crankshaft small. For this purpose, each connecting rod (23) has a power application point (49) at the crank pin (22), which is displaced in the direction of the bearing (13) in relation to the axial center of the crank pin (22).
