Abstract : This invention is a spring-biased valve assembly that will not corrode, gall, or otherwise wear, and that is for use in selectively controlling a flow of liquid fuel. The valve assembly, in its preferred embodiment, is eminently suitable for use in a gas turbine engine to keep the fuel manifold of the afterburner full when not operating, and to effectuate equal distribution of the fuel flow to a plurality of spraybars in the afterburner section. Accordingly, the principal object of this invention is to teach the structure of the preferred embodiment of the above-described valve assembly, wherein the simplicity of the structural form of the housing of the assembly enables the use of tungsten carbide for the housing, which material would not otherwise be useable in this assembly, and which is not useable in prior art valve assemblies because of their complex structural form.
