How do oil pumps work?

Oil pumps are crucial components in internal combustion engines that ensure proper lubrication by circulating engine oil. Typically driven by the engine's crankshaft, the pump's main function is to generate pressure that forces oil through a network of passages and channels. As the engine runs, the pump draws oil from the oil pan and pushes it through the engine's oil galleries. This oil reaches critical components like bearings, camshafts, and pistons, forming a lubricating film that reduces friction and heat. The oil also helps carry away debris and contaminants. Once the oil has completed its lubrication cycle, it returns to the oil pan, where the process begins anew. Oil pumps are vital for maintaining engine longevity and performance, as they ensure that all moving parts remain properly lubricated and protected from wear and damage.
