Abstract

The invention concerns a piston compressor, particularly a hermetically enclosed piston compressor, with a housing, in which a motor is arranged, the motor having a crankshaft with a vertically standing crank pin that has in its upper front side an opening, which is connected with an oil supply arrangement. It is endeavored to reduce an external oil circulation. For this purpose, the opening is provided with a limiting arrangement, which limits an axially directed movement of lubricating oil from the opening to a predetermined area.
