ABSTRACT:
A valve for setting the dampening level of a fluidic suspension strut is disclosed herein. The valve is especially suited for use within suspension struts of the kind having a cylinder, a telescopically interfitted piston, and an annulus between the cylinder and the interfitted piston. The valve includes a valve body, a valve stem, a housing, and a pressure sensing assembly. The valve responds to steady-state, load-induced pressure variations in the piston to regulate the flow of the fluid and the resulting damping characteristics of the strut.
