摘要： An industrial gas spring with a pressure chamber in a casing with an end wall, a piston rod received at least in part in the casing for reciprocation between extended and retracted positions and a pressure relief assembly carried by the end wall. The pressure relief assembly may have a membrane communicating with the pressure chamber and a plunger configured to breach the membrane when engaged and moved by the piston rod when it overtravels its design intended retracted position.

摘要： 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.

摘要： A gas spring with a casing with an axially extending side wall, an open end and a closed end wall spaced from the open end and a pressure chamber provided in part by the walls to receive a gas therein under pressure and a piston rod slidably received in a housing received in the casing and movable between extended and retracted positions. A pressure relief collar slidably carried around the piston rod and normally projecting axially outwardly of the casing can be displaced axially inwardly during an overtravel condition of the piston rod to displace a portion of a piston rod seal to open an overpressure relief path to allow pressurized gas in the pressure chamber to escape to the outside of the gas spring.
