Retrofits in shock absorber retrofits in shock absorbers

摘要

A shock absorber comprising a pressure cylinder having a valved piston reciprocally disposed therein, a reserve tube surrounding the pressure cylinder and defining a fluid reservoir therewith, valve means for selectively controlling fluid flow between the pressure cylinder and the reservoir, a resilient elastomeric diaphragm extending around the outer periphery of the reserve tube, means defining a fluid cavity between the reserve tube and the diaphragm, means for communicating fluid between the reservoir and the cavity and, an outer housing member surrounding the diaphragm and providing an area into which the diaphragm may expand as fluid is communicated into the cavity.
