Abstract

The invention relates to a valve device with adjustable compression damping. The valve device comprises a valve seat, a valve sleeve, a valve body, a valve rod, a low-pressure valve pin, a high-pressure valve pin and a sliding valve assembly, wherein a plurality of flow guide holes are formed in the side wall of the valve sleeve in circumferential arrays, and the low-pressure valve pin and the high-pressure valve pin are both axially slidably arranged on the upper portion of the valve seat through springs correspondingly, drainage holes are formed in the upper portion of the low-pressure valvepin and the upper portion of the high-pressure valve pin correspondingly, and the sliding valve assembly is located in a sliding valve cavity. A shock absorber set for preventing vehicle roll comprises two shock absorbers, and each shock absorber comprises an oil storage cylinder, a working cylinder, an intermediate cylinder and the valve device. The invention aims to solve or at least relieve the problems that a traditional compression valve depends on an electric control system and a sensor, the product cost is high, and the system reliability is low, and provides the valve device with adjustable compression damping.

Description

technical field [0001] The invention relates to the technical field of shock absorbers, in particular to a valve device with adjustable compression damping. Background technique [0002] The compression valve system of twin-tube hydraulic shock absorbers commonly seen in the market is generally composed of a compensation valve and a compression valve. When the shock absorber is in the compression stroke, the oil can only flow out through the circulation valve and the compression valve to generate damping force. The structure, manufacturing and assembly process of the compression valve are relatively simple and become the mainstream of the current hydraulic shock absorber valve system, but its shortcomings are also obvious. The singleness of its oil passage also determines the compression of this structure after the shock absorber is assembled. The damping force value cannot be adjusted, so that the comfort and handling of the vehicle cannot be taken into account. [0003] A...
