    摘要: Fuel injection apparatus 54, for a gas turbine engine, includes pilot fuel injection circuits 42 which supply pilot injectors 44 with fuel from a manifold 60, through a pilot control valve 46. The state of the control valve 46 is set by pneumatic pressure in the manifold 56. Main injectors 50 are supplied with fuel from the manifold 60 by main injection circuits 48, through main valves 52. The state of the main valves 52 is set by hydraulic pressure in a manifold 58. Accordingly, control signals to the valves 46, 52 are conveyed independently by means of the pneumatic manifold 56 and the hydraulic manifold 58.
