ABSTRACT:
A fuel control system has a main metering device and a flow limiting throttle valve arranged in series, and a spill valve responsive to a pressure drop within the system, for maintaining this pressure drop constant, the arrangement being that when the throttle valve is fully open the spill valve is responsive to the pressure drop across the metering device only, and in all other conditions of the throttle valve the spill valve is responsive to the total pressure drop across the series arrangement of the metering device and throttle valve.
