ABSTRACT:
In a gas turbine engine, fuel is supplied to a fuel metering valve which is connected to a shutoff valve. The shutoff valve supplies fuel to a manifold. Fuel flow between the manifold and main fuel nozzles is controlled by fuel staging valves while the pilot nozzle is connected directly to the manifold by a fuel line which may include an orifice. The orifice is designed to match the flow in the pilot nozzle with the flow in main nozzles when the fuel staging valve is on.
