PROBLEM TO BE SOLVED: To provide a fuel supply device of a gas turbine engine in which fuel flow amount can be controlled with a simple structure at low cost, and fuel sealing property can sufficiently be secured.SOLUTION: The amount of fuel distribution to a pilot fuel passage 64 and a main fuel passage 65 is automatically adjusted according to fuel pressure by a fuel distributor 66 provided on a branch part of a collecting fuel passage 63, the pilot fuel passage 64, and the main fuel passage 65. According to the fuel pressure, a pilot port 76 and a main port 77 are gradually valve-opened or valve-closed to adjust the fuel distribution amount to the pilot fuel passage and the main fuel passage in the respective fuel pressure, and respective ports are valve-closed by the driving of respective needle valve bodies 101, 102 through a drive body 72. |
