AI Technical Summary
Technical Problem
In the existing technology, noise is generated when the plunger contacts the end face of the valve seat. Although the sealing gasket has a buffering effect, the effect is limited and it cannot effectively control the noise.
Method used
The design employs a side-fitting mechanism, utilizing the air inlet on the side wall of the plunger to match or offset the air outlet of the valve seat. Combined with the first and second sealing rings to prevent air leakage, this allows the air inlet and outlet to be connected or closed, avoiding collision between the plunger and the valve seat.
Benefits of technology
It effectively reduces noise, ensures the sealing of the valve body, and avoids collisions and air leakage between the plunger and the valve seat.

Abstract
The application belongs to the technical field of vehicle suspension systems, and particularly relates to a low-noise stiffness valve, which comprises a valve seat and a plunger. The valve seat is provided with a central passage. The side wall of the valve seat is provided with a gas outlet hole in communication with the central passage. The inner wall of the valve seat is provided with a first sealing ring and a second sealing ring. The first sealing ring is located above the gas outlet hole, and the second sealing ring is located below the gas outlet hole. The plunger is slidably arranged in the central passage. One end of the plunger is provided with a communication cavity in communication with the central passage. The side wall of the plunger is provided with an air inlet hole in communication with the communication cavity. The application replaces the end face contact sealing cooperation between the existing plunger and valve seat with side face cooperation. There is no collision between the plunger and the valve seat, and the noise can be effectively reduced. The first sealing ring and the second sealing ring prevent the gap between the plunger and the valve seat from leaking, and ensure the sealing performance of the valve body.
