Abstract
A hydraulic strut for use with a vehicle suspension system includes a reciprocating piston rod and piston in an inner cylinder. A piston valving assembly is carried by the piston and controls the flow of fluid between upper and lower chambers of the inner cylinder. A base valving assembly controls the flow of fluid from the inner cylinder to a reservoir. A bypass valving assembly, selectively dependent upon a rotation movement input when the vehicle is steered, permits fluid flow to travel between the upper and lower chambers of the inner cylinder without traveling through the piston valving assembly.
