ABSTRACT:
A valve for simultaneously controlling the flow of two propellant fluids to a rocket engine. The valve has separate flow passages for the two fluids and a separate valve element for controlling the flow through each passage. A single solenoid simultaneously controls the movement of both valve elements and each valve element provides a portion of the path for the magnetic flux generated by the solenoid. Each flow passage leads to a series of openings in a wall of the engine, such openings serving as injection orifices to the combustion chamber of the engine. The openings are of small diameter and length so that the volume of the openings between the valve seat and the combustion chamber is relatively small. Separation of the two flow passages is accomplished without the use of flexible or sliding seals.
