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