Abstract
An adjustable shock absorber is provided that includes a body having a fluid passageway with first and second passages in fluid communication with one another. A valve assembly is arranged between the passages and includes a plunger that is adjustable between a plurality of positions corresponding to a plurality of fluid flow positions. The valve assembly includes a metering valve having a orifice in a disc, and the plunger includes a needle with a portion disposed in said orifice to provide flow area. The flow area is changed when the plunger moves. The valve assembly also includes a blow-off valve in which the disc is biased to a closed position by a spring arranged between the plunger and the disc. Movement of the plunger changes the loading on the spring. An adjustment knob has a cammed surface that cooperates with the plunger so that as the adjustment knob is rotated the cammed surface moves the plunger. In this manner, the blow-off and metering valves may be adjusted simultaneously, or independently if the metering and blow-off valves are separated, to provide more desirable shock absorber adjustment. Moreover, adjustment of the shock absorber is not necessarily limited to a …
