ABSTRACT:
An adjustable shock absorber is provided having means for adjusting the damping curves and breakover characteristics of the shock absorber while the shock absorber is installed in a vehicle. The shock absorber has a generally elongated cylindrical body defined by concentrically mounted inner and outer cylinders. A pair of end caps mounted on the ends of the inner and outer cylinders retain a working medium therein. Disposed within the elongated inner cylinder is a movable piston defining upper and lower chambers. Working medium is transportable between the upper and lower chambers via an annular passage formed between the inner and outer cylinders. A plurality of adjustable valves are disposed in the path of transportation of the working medium for providing an adjustable damping function.
