Patent ID: 7152570

Claim:
A lubrication system for an internal combustion engine with at least one piston reciprocating in an engine cylinder, said lubrication system comprising: an oil pump ( 11 ) with adjustable feed pressure and being controlled via a pressure reducing valve ( 18 ) which is acted on by the working oil pressure via a pressure outlet ( 21 ) that is hydraulically connected to a bearing ( 24 ) of the internal combustion engine, said bearing ( 24 ) being lubricated by the lubrication system; and said pressure outlet ( 21 ) being arranged in a crankshaft bearing cap ( 22 ) of the engine and a mouth of said pressure outlet ( 21 ) being displaced in a direction of rotation ( 25 ) of a shaft ( 23 ) away from a mouth of a feed duct 14 of the lubrication system to the bearing so that the rotation speed of the shaft influences the oil pressure in the bearing.
