Abstract: 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.

Abstract: An inflation valve has a valve housing having an inner wall, a cylindrical inner chamber terminating in a gas outlet, and a gas inlet bore providing fluid communication between the inner chamber and a pressurized gas source. A piston enclosed in the inner chamber has at one end a head directed toward the gas outlet and at the opposite end a valve actuator connector. The piston further has a gas inlet seal, positioned between the head and the actuator connector, that releasably seals the gas inlet bore from the inner chamber when the piston is in a normal, non-actuated position. A valve actuator connected to the actuator connector operates to pull the piston, thereby moving the gas inlet seal away from the gas inlet bore and putting the inner chamber in fluid communication with the gas inlet bore and pressurized gas source.
