Abstract
An adjustable shock absorber includes a shock rod having a longitudinal axis. A shock body is disposed around a portion of the shock rod, the shock body defining a first fluid chamber therein and being slidable along the longitudinal axis. A piston is disposed on the shock rod in sealing engagement with the shock body. The piston has at least one channel therethrough in communication with the first fluid chamber. At least one valve is in fluid communication with the channel to control fluid movement through the channel. A support is movable longitudinally along the shock rod and is disposed adjacent to the valve. An adjustment mechanism is provided for altering a longitudinal position of the movable support to adjust the valve's operation by altering the fluid movement through the channel.
