Refrigerant compressor, particularly semi-hermetic refrigerant compressor, has multiple star-shaped cylinders arranged around crankshaft, where cylinders are locked by cylinder head in each case

摘要

The refrigerant compressor (1) has multiple star-shaped cylinders (6) arranged around a crankshaft (11). The cylinders are locked by a cylinder head in each case. A piston (7) is arranged in each cylinder, which is driven by the crankshaft. The circumferential wall between two cylinders has a larger distance to the crankshaft in an area than in another area between the remaining cylinders.
