Patent ID: 7093420

Claim:
A fuel flow dividing valve for selectively conveying fuel from a fuel source to at least a primary gas turbine engine intake manifold and a secondary gas turbine engine intake manifold during engine operation, comprising: an inlet port coupled to a fuel source; a movable member with a position dependent on fuel pressure from the inlet port; a pressure differential actuated flow dividing valve portion having a movable valve spool with a flow restricting inlet and first and second substantially unrestricted outlets, the first outlet coupled to the flow restricting inlet independent of valve condition for supplying fuel to the primary manifold, and the second outlet coupled to the flow restricting inlet for supplying fuel to the secondary manifold when the pressure differential across the flow restriction exceeds a thresholds, wherein the movable member transitions from a position blocking fuel flow from the inlet port to the flow restricting inlet to a position allowing fuel flow from the inlet port to the flow restricting inlet in accordance with the fuel pressure from the inlet port.
