An Impulsive High-Pressure Gas Valve for Plasma Devices

Abstract

An impulsive gas valve with an electrodynamic drive of the locking element is described. The valve is designed to inject working gases into a discharge channel of plasma devices of the compression and acceleration types. The key gas-dynamic and electrical characteristics of the impulsive gas valve are presented. The valve is capable of forming gas pulses with a wide range of gas-dynamic parameters: the supplied volume of the working gas is 30–540 cm³ per pulse (at atmospheric pressure) and the gas pressure in the flow is as high as 760 Torr.
