Abstract
A fuel supply and distribution system is provided for a gas turbine engine wherein a plurality of flow dividing valves disposed about a manifold are positively controlled through an actuator which interconnects the flow dividing valves by linkage means extending through the manifold thus preventing sticking or seizing of the pressure regulating valves on account of contaminant particulate matter in the fuel.
Claims8
A fuel supply and distribution system comprising:
- a manifold tube for receiving a flow of pressurized fuel;
- an actuator having a piston slidably disposed therein wherein the piston is actuated in response to changes in the pressure of the fuel in the manifold tube;
- a plurality of flow dividing valves disposed about the manifold tube each including a metering piston translatably disposed therein for regulating the flow of fuel from the manifold tube;
- linkage means extending through the manifold tube interconnecting the actuator with the flow dividing valves such that movement of the actuator piston is simultaneously imparted to the flow dividing valve pistons;
- wherein the linkage means includes a plurality of circumferentially spaced apart pivot arms disposed about the inside of the manifold tube wherein one end of each pivot arm is pivotally connected to the manifold tube with the other end of a selected number of pivot arms respectively engaging the actuator and metering pistons such that rotation of the pivot arms about their respective points of pivot operate to respectively translate the actuator and metering pistons, and a plurality of links interconnecting the pivot arms so that the pivot arms rotate in unison about their respective points of pivot in the manifold tube.
