AI Technical Summary
Existing agricultural machinery engine valve assemblies suffer from reduced sealing performance due to spring fatigue after prolonged use, failing to effectively ensure the engagement of the valve and valve seat, resulting in air leakage.
An adjustment mechanism is adopted, including components such as a base, hollow shaft, outer spring, inner spring, sealing seat, and pressure sensor. By adjusting the movement of the base and the deformation of the spring, the sealing between the valve body and the valve seat is ensured. Combined with the meshing of worm gear, worm wheel, and gear, the spring force can be precisely adjusted.
It improves the sealing performance of the valve assembly, avoids gaps, extends the service life of the valve assembly, and improves the combustion efficiency and power output of the engine.
