Title: Fuel control system for gas turbine engine

Abstract: A servo-operated shut-off valve for a gas turbine engine fuel system has a main valve control element and an electrically-operated pilot valve control member for controlling a servo-operating pressure for the main valve. The pilot valve control member and main valve control element are resiliently interconnected so that movement of the main valve control element urges the pilot valve control member in a direction to cause the servo pressure to maintain that movement of the main valve control element.
