ABSTRACT:
A fluid pressure actuated assembly includes a casing made of a flexible resilient material, such as rubber or polyurethane, a coiled tension spring sleeved on the casing for biasing the casing to move toward a retracted position, and a coiled spacing spring interposed between the tension spring and the casing for preventing any wall of the casing from being clamped between any two adjacent turns of the tension spring. When a compressed fluid is applied to the interior of the casing, the casing extends.
