Oil Pump

Oil pumps are positive-displacement pumps responsible for circulating engine oil under pressure to critical components like the crankshaft, camshaft, and valve train. Typically located within the engine’s oil pan or integrated into the timing case, they draw oil from the pan and deliver it throughout the lubrication system. Designs include gear, vane, and rotor types, each utilizing close-tolerance machining to maintain consistent flow and pressure. Output is regulated by pressure relief valves to prevent engine damage from excessive oil pressure. Modern pumps frequently incorporate variable displacement technology for optimized oil delivery based on engine speed and load.
