  • Shock absorber
    Patent number: 5058715
    Abstract: A shock absorber including a piston with two relatively movable elements defining a variable-sized, fluid-filled space in communication with a shock absorber chamber through a vent. The size of the space is decreased when subjected to external fluid pressure and fluid flow through the piston is modified in response to such decrease. The rate of space size decrease is controlled by means for selectively changing the effective size of the vent.
