A self-balancing two-way flapper valve for shock absorbers

Abstract

The invention discloses a self-balancing two-way baffle valve for a shock absorber, which comprises a baffle valve body, a baffle valve core, a driving device and a return spring. The baffle valve core separates the baffle valve body into left and right chamber and the right chamber, the baffle valve body is evenly distributed with oil holes, the inner side of one end of the baffle valve body extends a limited protrusion, and there is a small through hole on the baffle valve core to connect the left chamber and the right chamber of the baffle valve body. There is a return spring between the baffle spool and the driving device, and the driving device drives the baffle spool to move horizontally in the baffle valve body through the return spring, and the opening and closing of the oil hole is realized by the movement of the baffle spool, and Combined with through holes to ensure oil flow and ensure equal pressure in the left and right cavities of the baffle valve body; the baffle valve in the present invention has simple structure, fast frequency response, reliable operation, long service life, and low cost, and can solve the problem of the left and right cavities of the baffle valve core. The problem that the unequal working pressure affects the working performance of the baffle valve.

Description

technical field [0001] The invention relates to a self-balancing two-way baffle valve for a shock absorber, especially a low-pressure fluid as a transmission medium, which is suitable for an automobile shock absorber system and precisely controls the oil inside the shock absorber, belonging to fluid control technology field. Background technique [0002] At present, the hydraulic valves used in the automobile shock absorber system usually use thread transmission to switch or adjust the size of the liquid flow. The unequal pressure at both ends of the valve core makes it difficult to open and close the valve core, and the friction between the valve core and the valve body is seriously damaged. The nozzle baffle valve is to change the opening of the liquid flow path by changing the relative displacement between the nozzle and the baffle to achieve control. The gap between the orifice and the nozzle is small and easy to block, and the anti-pollution ability is poor. [0003] ...
