Abstract
The invention relates to a piston compressor, particularly a hermetically enclosed refrigerant compressor, with a crank drive, having a crank shaft with an eccentric crank pin and an oil channel arrangement, and a connecting rod with a first piston-side connecting rod eye and a second pin-side connecting rod eye, said eyes having between them a connecting rod shank with a longitudinal channel, which opens into the connecting rod eyes.In this compressor, it is endeavoured to improve the lubricating conditions.For this purpose a bearing element is arranged between the crank pin and the second connecting rod eye, which is unrotatably connected with the second connecting rod eye under formation of an oil channel, the longitudinal channel communicating with the oil channel and a control arrangement being provided, which ensures a communication between the oil channel and the oil channel arrangement at least once per rotation of the crank pin.
