VORTEX SHOCK ABSORBER WITH ABSORBING FORCE RELIEF MEANS

摘要

A shock absorber is provided with a relief valve within a thrusting piston. The relief valve defines a vortex chamber therein and is movable in response to the pressure difference between a high pressure chamber and a lower pressure chamber. The valve is movably urged toward an initial position by a set spring which defines the set pressure of the shock absorber.
