Claim 10:
11. A fuel supply system comprising:
a fuel pump;
a combustor;
a fuel metering valve coupled to the fuel pump and the combustor through a fuel supply line;
a throttle valve coupled to the fuel supply line downstream of the fuel metering valve, the throttle valve having a controllable position to modulate a flow of fuel by bleeding off a portion of fuel supplied to the combustor;
a pressure sensor coupled to the throttle valve; and
a controllable servo coupled to the throttle valve and the pressure sensor, the controllable servo to set the controllable position of the throttle valve based on a pressure difference across the fuel metering valve as sensed by a second pressure sensor.
