Abstract
An improved hydraulic strut (30) for mounting a moveable structure (24) to a support structure, the strut having an outer telescoping member (20) and an inner telescoping member (32). The outer telescoping member defines a first hydraulic chamber (402) and a second hydraulic chamber (400), connected by a fluid flow restrictor (100). The inner telescoping member includes a main piston (200) that translates within the second hydraulic chamber between a closed position, where the inner telescoping member is fully retracted into the outer telescoping member, and an open position, wherein the inner telescoping member is fully extended from the outer telescoping member.
