Patent ID: 7257939

Claim:
Sliding-Action Magneto-Mechanical Injector Throttling Device in combination with a vortex injector, the injector comprising a body; a combustion chamber within the body, the body having a plurality of injection orifices leading to the chamber; a fuel manifold and an oxidizer manifold, the manifolds being coupled to the body and each having a top and a bottom, the manifolds further communicating with the orifices of the chamber so as to be able to input a fuel and an oxidizer, respectively, to the chamber through the orifices, said Throttling Device comprising: a first means for controlling the mass flow of the input fuel, said first controlling means being coupled to said fuel manifold; and a second means for controlling the mass flow of the input oxidizer, said second controlling means being coupled to said oxidizer manifold, both of said controlling means selectively varying the effective sizes of the injection orifices to provide a high-efficiency throttling of the fuel and oxidizer flow into the combustion chamber so as to produce power output of a desired level.
