Abstract:
A fuel control system for supplying metered quantities of fuel from a fuel supply, through a fuel pump, a metering valve and a pressurizing valve to a plurality of engine fuel manifolds including an atomizer nozzle manifold, an upper air blast nozzle manifold and a lower air blast nozzle manifold, an improved fuel flow dividing arrangement intermediate the pressurizing valve and the engine fuel manifolds for appropriately distributing fuel flow among the plurality of engine fuel manifolds comprising:a concatenated pair of two-way splitter valves comprising a first splitter valve distributing the fuel flow between the atomizer nozzle manifold and the remaining air blast manifolds, and a second splitter valve distributing the down stream fuel flow from the first splitter valve between the upper and lower nozzle manifolds.
