ABSTRACT:
A telescopic hydraulic shock absorber for a motor vehicle has a piston with a frustoconical valve element that provides a bypass passage from the rebound chamber to the jounce chamber during a low velocity rebound stroke of the piston with respect to the pressure tube. The frustoconical valve element is constructed to be sufficiently resilient to become seated and close off the bypass passage in response to a relatively high velocity rebound stroke such that all fluid is forced through the rebound ports and the rebound valve to provide higher damping than when the bypass passage is open.
