摘要： A fuel control system for a gas turbine engine includes a metering valve for metering a flow of fuel, a throttling valve for maintaining a pressure drop across the metering valve, the throttling valve being shiftable between an open state and a shutoff state blocking an outlet of the metering valve, a primary control pressure supply for supplying a primary control pressure to the metering valve for controlling the position of the metering valve, a backup control pressure supply, a transfer valve shiftable between a first position connecting the primary control pressure to supply to the metering valve and a second position connecting the backup control pressure to the metering valve, and an electrohydraulic servovalve (EHSV) operably connected to the throttling valve and the transfer valve and controlling the state of the transfer valve and the position of the throttling valve. Also a method for controlling a transfer valve and a throttling valve.
