Abstract
A gas spring in which a valve permits flow of a pressurized fluid between two compartments of a cylinder cavity separated by a piston for movement of a piston rod attached to the piston outward of the cavity while inward movement of the piston rod is normally blocked by a mechanism which responds to a predetermined, axial, inward force applied to the piston rod for releasing the same.
