Abstract
A valve having a translatable annular slot communicates with discretely shaped and judiciously located elongated, variable width slots for metering fuel to individual fuel nozzles in a burner of a jet engine without changing the fuel scheduling characteristics of the fuel control. The valve can have sequential lighting capabilities in the event that the burner is designed with this feature.
Claims6
A fuel distributing valve for directing metered fuel flow from a fuel control controlling the operation of a gas turbine engine to the fuel nozzles of the burner of that gas turbine engine, said fuel distributing valve having a cylindrical casing, a sleeve affixed in a bore of said cylindrical casing having a plurality of spaced circumferential elongated slots of varying widths communicating with corresponding complimentary outlet ports in said casing communicating with said nozzles, a piston in sliding relationship with said sleeve having an annular groove, means for feeding fuel to said annular groove so that the position of said annular groove relative to said elongated slots determines the amount of fuel permitted to enter each of said nozzles.
