The Role of the Engine Valve Spring Guide

The role of the valve spring seat is to ensure that the valve immediately sits down and tightly fits, so as to avoid the valve beating when the engine vibrates and destroys its sealing. The function of the installation preload force caused by the pre-compression of the valve spring is to overcome the inertia force of the valve and its transmission parts in the process of valve closing, eliminate the clearance caused by the inertia force between the transmission parts, and realize its function.

1. the natural vibration frequency to improve the valve spring is trying to improve the valve spring stiffness, such as bold or reduce the spring coil diameter wire diameter. This method is simple, but because of the spring stiffness, add the impact load between power consumption and spare parts.

2. use double valve springs each valve is installed two root diameter is not the same, the opposite of inside and outside the spring. Because the natural vibration frequency of the spring, when a spring resonance occurs, vibration and can rise to another spring. Spring break a spin to the contrary, to avoid the card into another root spring, affect the good spring stuck or damage. In addition, a one thousand a spring break, and a spring can still maintain the valve does not fall into the cylinders.

3. use different pitch spring this spring at work, one end of the pitch of small composite gradually, have the effect turns gradually decreases, and the natural frequency will increase gradually, make resonance impossible.

4. the use of pitch single spring, such as in them band and an interference fit of damping friction plate to eliminate resonance.

Product Application

Cummins engines are mainly used in commercial vehicles, construction machinery, mining equipment, marine power and generator sets, etc.
