Abstract

A valve includes a valve body having a gas inlet and a gas outlet. The valve body has an internal circumferential wall defining a gas passageway between the gas inlet and gas outlet. The inlet of the valve body is connectable to a source of pressurized gas. The valve also includes a rupture disc provided adjacent said gas inlet, wherein the ruptured disc is configured to prevent flow of gas through said inlet when intact and to allow flow of gas through said inlet when ruptured. The valve includes ribs radially extending from the internal circumferential wall, said ribs extending longitudinally in the direction to the gas outlet and from the gas inlet in a maze-type pattern. The ribs may be formed in a printed pattern to form a maze with dead-ends.
