ABSTRACT:
Method and arrangement for providing a lubrication system for an internal combustion engine with at least one piston reciprocating in an engine cylinder. The lubrication system includes an oil pump (11) with adjustable feed pressure which is controlled via a pressure-sensing means (18) which is acted on by the working pressure of the oil. The pressure-sensing means (18) is acted on via a pressure outlet (21) which is hydraulically connected to one of the bearings of the internal combustion engine which are lubricated by the lubrication system.
