Top 10 valve spring Manufacturers in the world - Blog

Introduction to Valve Springs

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 valve spring is to keep the engine valves closed when they are not supposed to open and to return the valves to their closed position after they have been opened by the camshaft. This precise control of valve movement is essential for the engine to operate efficiently, maintain compression, and ensure smooth power delivery. Valve springs need to have high fatigue resistance, as they are subjected to repeated stress cycles during engine operation. They also need to have the right stiffness to provide the necessary force to close the valves effectively.
