FAST ACTING VALVE FOR FEEDING LIQUID, E. G., FUEL COMPONENTS IN LIQUID ROCKET ENGINES,

Abstract : A fast acting valve for feeding liquid, for example fuel components in liquid rocket engines, having a body, membrane, overlapping passing section and membrane piercing organ with pyro drive is described. The pyro drive is not connected in power scheme with the body and is separated from the flow through section by a flexible diaphragm, controlling the piercing organ and isolating the body from high pressure gases.
