Application

In the engine operation, the oil quenching - tempering spring steel wire spring is not only used to ensure that the valve is closed when the need to close, more importantly, in the whole process of gas distribution, to ensure that the valve in accordance with the shape of the valve cam profile to determine the movement of movement . In order to prevent the tappet (or rocker) from momentarily leaving the cam profile, that is to ensure that the valve sealing performance, the valve spring should have sufficient rigidity, so that the pressure is always greater than the valve out of the trend of inertia force. However, if the spring stiffness is too large, the valve during the movement of the relevant parts to be overcome the corresponding increase in the spring force, which requires increased strength and wear resistance of parts. The selected spring stiffness is appropriate to reduce the noise, vibration and wear generated by the valve movement. In addition to meet the long-term high-speed operation of the engine, the valve spring also has excellent anti-fatigue performance.
