A fuel system for a gas turbine engine that utilizes a centrifugal pump. The system includes a fuel metering valve that is adapted to set a metered flow of fuel, and a throttle valve that is adapted to accurately control pressure drop across the fuel metering valve. The throttle valve has at least two variable orifices and a compensation chamber between the variable orifices. The throttle valve includes a differential valve piston slidable in a valve body. The differential valve piston comprises working surfaces of at least two different diameters such t...
What is claimed is: 1. A fuel system for a gas turbine engine, the fuel system comprising: a high pressure centrifugal pump adapted to pump fuel from a fuel supply; a fuel metering valve adapted to set a metered flow of fuel; a throttle valve adapted to control pressure drop across the fuel metering valve, the throttle valve having at least two variable orifices and a compensation chamber between the variable orifices, the throttle valve being movable to simultaneously change degrees of opening of the variable orifices, the fuel system when in operatio...
