Fast Operating Valve for Feeding a Liquid, E.G., A Fuel Component into a Liquid-Propellant Rocket Engine

摘要

The object of the invention is a rapid-action valve for the feeding of a liquid, for example, the fuel component into a liquid-propellant rocket engine, which contains a body, a membrane covering the passage section of the flow part, and a membrane-piercing organ with a pyroactuator. For the purpose of lessening the weight while preserving the dependability the 'piroprovod' (fire duct) is designed not connected in the power system with the body and separated from the flow part by a flexible diaphragm controlling the piercing organ and insulating the body from the highpressure gases.
