Introduction to Valve Spring
Valve springs are crucial components in internal combustion engines, compressors, and other machinery. Their primary function is to ensure proper valve operation by exerting the necessary force to close the valve after it has been opened by the camshaft. This precise control of valve movement is essential for the efficient and reliable performance of the engine, as it directly affects factors such as intake and exhaust gas flow, compression ratio, and overall power output. Valve springs must be designed and manufactured to meet strict specifications in terms of strength, durability, and fatigue resistance, as they endure high levels of stress and cycling over their service life.
