Oil Pump


a device for pumping oil under pressure, used in the lubrication systems of internal combustion engines, the hydraulic drives of machinery, and so on. Gear-type and piston-type (reciprocating) oil pumps are the most commonly used types. The oil-diffusion (oil-vapor) pumps used in vacuum technology are also called oil pumps.
