Abstract
A gas spring for forming equipment. A casing includes an axially extending side wall, an open end, a transversely extending closed end wall axially spaced from the open end, and a pressure chamber established in part by the side and end walls to receive a gas under pressure. A piston rod is received at least partially in the casing for reciprocation between extended and retracted positions. A piston rod housing is received at least in part in the casing between the piston rod and the casing. An overtravel pressure relief feature includes a vent path that is disposed between the pressure chamber and the outside of the gas spring and that includes a vent passage through the side wall of the casing and a seal that sealingly interrupts the vent path, wherein displacement of the housing into the casing results in opening of the vent path.
