Device for Cutoff of Fuel Supply to a Liquid-Propellant Rocket Engine

摘要

A device for cutting off the supply of fuel to a liquidpropellant rocket engine is described. The valve consist of a body (housing) inside of which there are conical seats and there is placed a valve controllable by a pyromechanism. The plate and stock are provided with conical sealing bands. The sealing bands have the distinguishing feature of creating a more dependable hermetic sealing through the assuring of independent wedging of the sealing bands. The stock of the valve is designed from two parts mutually movable in the axial direction, joined to each other by a sleeve. (Author)
