Fluid flow control valve for a shock absorber.

摘要

A control valve on the rod guide of a shock absorber permits controlled fluid flow in one direction and prevents fluid flow in an opposite direction. The valve is biased into its normal sealed position by a dual purpose spring arranged to bias a circumferential portion of the valve against the rod guide and also arranged to bias a resilient end closure seal against an end closure cap of the shock absorber. Due to deflective operation of the valve the dual purpose spring maintains a constant, non-fluctuating force on each the valve and the resilient end closure seal.
