ABSTRACT:
A variable damping shock absorber is disclosed. The variable damping mechanism is activated by depression of a pin on the upper end of a shock absorber piston. Depression of the pin causes a spring loaded ratchet drive to engage a ratchet on a slide valve to alternatively ratchet the valve and slide the valve between an open and blocking position between two or more transverse flowways in the lower end of the shock.
