VALVE SPRING Meaning and
Definition
-
A valve spring is a mechanical component used in internal combustion engines to provide the necessary force required to close and seal the intake and exhaust valves with the valve seats. It plays a crucial role in the proper functioning of the engine's valvetrain system.
The valve spring is typically a coiled, helical spring made from high-quality steel, designed to exert a certain amount of pressure or force that ensures the valves remain tightly closed while the engine is running. This spring is attached to the valve stem and the cylinder head, holding the valve in the closed position.
When the camshaft rotates and pushes the valve lifter or rocker arm, the valve spring is compressed, allowing the valve to open. As the camshaft lobes move away, the valve spring expands and returns the valve back to its closed position, ready for the next cycle.
Valve springs are specifically engineered to withstand the dynamic stresses and loads caused by the high-speed reciprocating motion of the valves. They are designed to maintain the optimal valve timing, prevent valve float or bounce, and ensure efficient combustion and smooth engine operation.
In high-performance or racing engines, valve springs are often upgraded to stronger and stiffer variants to withstand higher rpms and provide additional valve control. This is crucial to avoid valve float and maintain valve seating integrity, preventing any potential damage or loss of engine power.
In summary, a valve spring is a mechanical device that provides the necessary force to close the valves in an internal combustion engine, ensuring proper combustion and engine performance.

Etymology of VALVE SPRING
The word "valve spring" has a straightforward etymology rooted in the combination of the words "valve" and "spring".
1. Valve: The term "valve" originated from the Latin word "valva", which means "leaf of a door or folding shutter". Over time, the meaning expanded to include any device that controls the flow of a fluid or gas by opening and closing passages. The word "valve" was first recorded in English during the 14th century.
2. Spring: The word "spring" has ancient roots and can be traced back to the Old English word "springan", which means "to leap up, burst forth, or originate". It stems from the Proto-Germanic word "sprunganan", which has the same basic meaning. "Spring" has often been associated with the idea of sudden movement, growth, or rebounding.
