Oil pump

The oil pump in an internal combustion engine circulates engine oil under pressure to the rotating bearings, the sliding pistons and the camshaft of the engine. This lubricates the bearings, allows the use of higher-capacity liquid bearings and also assists in cooling the engine.

As well as its primary purpose for lubrication, pressurized oil is increasingly used as a hydraulic liquid to power small actuators. Of the first notable makes use of in this way was for hydraulic tappets in camshaft & valve actuation. Increasingly common recent makes use of may include the tensioner for a timing belt or variators for variable valve timing systems.
