Refrigerant compressor, particularly semi-hermetic refrigerant compressor, has housing and crank shaft, where crankshaft has diameter extension at its lower end, through which oil channel runs

摘要

The refrigerant compressor (1) has housing (2) and a crank shaft (11). The crankshaft has a diameter extension (19) at its lower end, through which an oil channel runs. The oil channel is arranged eccentrically to the crankshaft axis (36). The oil channel connects an oil pump arrangement (27) with an oil pressure chamber (21) enclosed between the crankshaft and a compressor block (5). The compressor block stays in connection with an interior (37) of the housing by a ventilation path.
