Embodiment Construction

[0026] The present invention relates to an automotive hydraulic shock absorber comprising a pressure cylinder containing hydraulic fluid, an auxiliary reservoir to which a portion of said hydraulic fluid flows back and forth due to the linear displacement of the piston assembly along the pressure cylinder.

[0027] figure 1 A cross-sectional view of an assembled shock absorber according to one embodiment of the invention is shown, wherein the shock absorber 100 includes an annular piston 110 provided with a plurality of cross fluid ports 120, details as figure 2 and 3 Shown is a compression shim stack 130 (consisting of 3 shims in this particular illustrative embodiment) on the bottom face 140 of the piston and a rebound shim stack 150 on the top face 160 of the piston. Piston 110 and shim stacks 130 and 150 are provided with a central bore adapted to receive one end of a piston shaft 170 located within a pressure cylinder 180 having an outflow port 190 to an auxiliary reser...

Abstract

An automotive hydraulic shock absorber, comprises a pressure cylinder, an auxiliary reservoir and a piston assembly, wherein said piston assembly comprises an annular piston comprised of a plurality of crossing flow ports on its upper and lower faces, a piston shaft, and shim stacks on both faces of said piston, partially or fully covering said flow ports, suitable to exert a resistance to the flow of hydraulic fluid in said pressure cylinder, when said piston travels through hydraulic fluid.

Description

technical field [0001] The invention relates to a shock absorber for a vehicle suspension system. More specifically, the present invention relates to a hydraulic shock absorber having a novel piston assembly. Background technique [0002] Wheeled vehicles in motion are subject to various road conditions (eg, bumps, potholes, obstacles) in which at least one wheel of the vehicle moves perpendicular to the direction of travel of the vehicle. Wheeled vehicles in motion are also subject to various driving situations (eg, acceleration, deceleration, cornering) in which the vehicle's body mass moves up or down relative to its wheels. Vertical movement of the vehicle's wheels or body affects vehicle safety (i.e. vehicle road grip, stability and steering effectiveness) and vehicle occupant comfort. [0003] The shock absorber is used together with the spring in the suspension system of the vehicle. It is connected (that is, installed parallel or concentrically) between the wheel a...
