description A fuel injector is disclosed for injecting fuel into a combustion chamber of a gas turbine engine which includes an injector nozzle having a central axis, first and second fuel injection paths in which one of the fuel injection paths supplies fuel to the injector nozzle while the other fuel injection path has an outlet displaced from the axis of the injection nozzle, a single fuel supply conduit which supplies fuel to both of the fuel injection paths, and a metering device which controls the flow of fuel from the single fuel supply conduit to the first and second fuel injection paths. The metering device may be a fuel metering valve assembly which has a piston defining a fuel metering orifice biased against a valve seat around an opening which communicates with the single fuel supply conduit. The piston is biased into engagement with the valve seat by a resilient bellows attached between the piston and a fixed structure.
