초록

Methods and apparatus are disclosed for providing shutoff, overspeed protection, and directional control of a bypass flow in a fuel delivery system (10) for a combustion engine, such as a gas turbine engine. A valve pack (72) is integrated into a fuel metering unit (12) and provides shutoff and overspeed protection, including verification of the operational integrity of the shutoff and overspeed protection components. A bypass directional control valve (150) is integrated into one embodiment of the fuel metering unit (12) and provides directional control...

청구항

1. A valve pack for use in a fuel delivery system for providing a desired fuel flow to an engine, the fuel deliver system including a metering valve having a metering state where the metering valve provides a metered fuel flow to the engine in response to a pressure differential between a reference pressure chamber and a modulated pressure chamber of the valve and a shutoff state wherein the metering valve blocks fuel flow to the engine in response to a pressure differential between the reference and modulated pressure chambers; the valve pack comprising...
