A fuel control for a gas turbine engine has a positive displacement pump (10) which directs fuel to a constant flow regulator (14) which generates a constant or fixed rate flow of fuel. A flow diverter (16) includes a dividing device which divides the constant flow of fuel between a discharge conduit (18) connected to the burner nozzles of the engine and a bypass conduit (20) connected to the inlet side of the pump. A computer (22) which is adapted to sense various engine parameters; and calculate fuel flow controls the flow dividing device in order to apportion the flow so that the calculated fuel flow is delivered to the engine.

In a fuel control for a gas turbine engine of the type having: a pump for delivering a pressurized flow of fuel; an inlet conduit for receiving fuel flow from the pump; a discharge conduit in fluid communication with the inlet conduit for delivering fuel to the engine; and a computer responsive to selected engine parameters for generating a signal indicative of a requested fuel flow, the improvement comprising: a constant flow regulator fluidly connected to the pump and the inlet conduit for generating a constant flow of fuel in the inlet conduit; a bypass conduit in fluid communication with the inlet side of the pump for returning fuel thereto; and a flow diverter, having first and second outlet ports, positioned in the inlet conduit such that it receives the constant fuel flow therein and has the first and second outlet ports in respective fluid connection with the discharge conduit and the bypass conduit, the flow diverter including a flow dividing device responsive to the signal from the computer for apportioning the constant fuel flow between the first and second outlet ports so that the requested fuel flow is delivered to the discharge conduit and the remainder of the constant fuel flow is delivered to the bypass conduit.
