摘要： A shock absorber is provided a piston stroke dependent variable shock absorbing characteristics by means of a first and second flow restriction valves associated with a piston (100). The first and second flow restriction valves (130, 140) are arranged in a fluid path for communicating first and second working chambers defined within a shock absorber cylindrical housing in series. The first flow restriction valve is associated with an orifice forming a part of the fluid path and has variable flow restriction rate in response to a pressure difference between the first and second chambers greater. The second flow restriction means is disposed in tandem fashion with the first flow restriction valve for providing a predetermined constant flow restriction rate in response to the pressure difference smaller than a predetermined criterion and providing a variable flow restriction as a function of the piston stroke speed in response to the pressure difference greater than the predetermined criterion.

摘要： A hydraulic shock absorber includes a hollow cylinder (10) which defines therein a fluid chamber filled with a working fluid, and a piston (12) which is reciprocally disposed within the fluid chamber and divides the fluid chamber into upper (14) and lower (16) chambers. The piston is formed with fluid passages (20, 22) for establishing fluid communication between the upper and lower chambers. Each of the fluid passages is controlled by a disk valve assembly (24, 50) comprising a plurality of elastic disk plates, so as to introduce the working fluid from one of the upper and lower chambers to the other chamber when fluid pressure in one of the chambers is greater than a predetermined value. The disk valve assembly has a bypassing fluid passage which has a plurality orifices configured so as to gradually decrease fluid pressure and flow velocity of the working fluid passing therethrough.
