The invention relates to a piston compressor, particularly a hermetically enclosed refrigerant compressor, with a crankshaft, which is axially supported in an axial bearing in relation to a bearing housing, and with an oil pump arrangement. In a piston compressor of this kind, it is endeavored to improve the lubricating properties. For this purpose, an oil distribution channel extending in the circumferential direction is arranged in the axial bearing between the crankshaft and the bearing housing, a control arrangement being arranged between the oil pump arrangement and the oil distribution channel, which control arrangement connects the oil pump arrangement with the oil distribution channel for a predetermined, short period, at least once during each rotation of the crankshaft.
