Abstract
A thruster for use in a spacecraft uses vaporized propellant in its combustion chamber (110). Normally two propellants are used of the kind used for main thrusters so that two vaporization chambers are needed. Pressure valves (108, 109) are controlled by electronic means (220) to maintain current pressure.
