A temperature compensation valve is hereby provided wherein the inner cavity of the valve comprises a puck, a metal piston (gas control device), and a spring. The spring serves to bias the piston towards the puck, and the puck expands and contracts proportionately in response to increases and decreases in temperature of the upstream gas. Furthermore, the piston will move accordingly, wherein an increase in temperature causes the expansion of the puck directing the piston in such a way to obstruct the orifice that allows the gas to pass through the valve, thereby controlling the gas flow to compensate for the pressure variations.

Temperature compensation valve

A reliable and economical apparatus for relieving pressure in a large aircraft cabin oxygen supply, where multiple oxygen cylinders are used concurrently. A series-parallel array of valves actuated by changes in differential pressure between the oxygen supply and the ambient cabin atmosphere provides overpressure relief The series connection of the valves reduces the risk of open-valve failures, while the parallel connection of sets of series-connected valves reduces the risk of closed-valve failures. The small number of valves used in its design reduces the cost of the apparatus. The series-parallel structure is optionally extended to larger numbers of valves to facilitate the use of less-expensive valves and supporting components without loss of reliability.
