• Specification

• Function and Application

1.Valve Control Function: In engines, spring assemblies are often used as valve springs. The valve is opened mechanically by the camshaft and closed by the tension of the valve spring. This ensures that the valve can be accurately closed in time during the engine's operation, preventing gas leakage and ensuring the normal operation of the engine's intake and exhaust processes. For example, in a Komatsu engine, the valve spring plays a crucial role in controlling the opening and closing of the intake and exhaust valves.

2.Shock Absorption and Overload Protection Function: In the undercarriage system of tracked vehicles, the spring assembly may be a track adjuster recoil spring. This kind of spring acts as a shock absorber, which can protect the undercarriage from impacts and overloads, prevent premature wear of components, and extend the service life of the track and idler systems.
