n. a pump that keeps a supply of oil on moving parts
Wikipedia
Oil pump may refer to:
- A hydraulic pump, which pressurizes hydraulic fluid in a hydraulic system
- An oil pump (internal combustion engine), a part of the lubrication system that pressurizes motor oil for distribution around the engine
- A pump jack, often used to pump oil out of wells
- A submersible pump, often used to pump oil out of wells
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 fluid bearings and also assists in cooling the engine.
As well as its primary purpose for lubrication, pressurized oil is increasingly used as a hydraulic fluid to power small actuators. One of the first notable uses in this way was for hydraulic tappets in camshaft and valve actuation. Increasingly common recent uses may include the tensioner for a timing belt or variators for variable valve timing systems.

Up I went and up, my ears concentrated upon the deep purring of my motor, my eyes busy always with the watch, the revolution indicator, the petrol lever, and the oil pump.
