Embodiment Construction

[0074] In order to enable your review committee to have a further understanding and understanding of the characteristics, purpose and functions of the present invention, the relevant detailed structure and design concept of the device of the present invention will be explained below, so that the review committee can understand the present invention The characteristics are described in detail as follows:

[0075] see Figure 1A as well as Figure 1B As shown, this figure is a three-dimensional exploded and assembled schematic diagram of a preferred embodiment of the valve mechanism of the present invention. The valve mechanism 1 has a pair of rotary valves 10 a and 10 b , a control valve 11 and a pair of rotary rods 12 and 13 . Each of the rotary valves 10 a and 10 b has a through hole 100 inside, and at least one flow path is disposed on the outer wall thereof. In this embodiment, the flow path is formed by a set of grooves 101 . As shown in FIG. 2A , which is a schematic bo...

Abstract

The present invention discloses a valve mechanism and a damping variable shock absorber that using the mechanism, wherein the valve mechanism is provided with a pair of rotary valves with outer valve wall of each rotary valve provided with a flow guiding path; a control valve which is set between the pair of rotary valves and presses against the rotary valves, and the end wall of the control valve pressing against the rotary valves is provided with a flow guiding port; and a pair of rotary rods which connect with the pair of rotary valves respectively. The pair of rotary rods can adjust the connected rotary valves to rotate separately, and adjust the relative position of the flow guiding path and the flow guiding port. Therefore, the valve mechanism described in the invention can adjust flow passage corresponding location on the valve body by rotating and control flow passage port size. Besides, the present invention also provides a variable damping shock absorber by utilizing the valve mechanism, and the valve mechanism flow passage port sized set inside the cylinder rod can be adjusted by rotating to adjust shock absorber damping, and further change shock absorbing effect of the shock absorber.

Description

technical field [0001] The invention relates to a design of a valve mechanism, in particular to a valve mechanism capable of adjusting the opening size of a flow channel to control the shock absorption effect of the shock absorber and a variable damping shock absorber using the mechanism. Background technique [0002] Generally, four-wheeled or two-wheeled vehicles drive on the road. The suspension system of the vehicle needs to have the ability to absorb the ground force and release and eliminate the vibration generated by the force, no matter in the compression stroke or the tension stroke. The suspension system components The shock absorber is the main shock absorbing and damping element. Generally, the damping force change control method of the adjustable shock absorber is achieved by the main valve of the shock absorber and the bypass oil circuit, and the bypass oil circuit has a structure with a variable valve port size to change the damping force. [0003] The dampin...
