Top 10 Cams Valve Spring Manufacturers in China - Blog

Introduction to Cams Valve Spring

Cams valve springs are crucial components in internal combustion engines. They play a vital role in ensuring the proper operation of the engine's valve train. The main function of a cams valve spring is to keep the valve closed when it is not supposed to open and to return the valve to its closed position after it has been opened by the camshaft. This precise control of valve movement is essential for efficient engine performance, including proper intake of air - fuel mixture and exhaust of combustion gases. High - quality cams valve springs need to have excellent fatigue resistance, high strength, and accurate spring rates to withstand the high - speed and high - stress environment within the engine.
