FUEL SUPPLY DEVICE FOR GAS TURBINE ENGINE

摘要

A fuel supply device of a gas turbine engine of the present invention includes a fuel divider 66 which divides fuel supplied from a collecting fuel passage 63 to feed the fuel to a pilot fuel passage 64 and to a main fuel passage 65. The fuel divider 66 includes a movable member 72 which is movable according to a fuel pressure at the fuel entrance 75 and opens and closes pilot ports 76 and main ports 77 according to a distance of the movement of the movable member 72. When the fuel pressure at the fuel entrance 75 is not higher than a predetermined value, the fuel is supplied only to the pilot fuel passage 64, while when the fuel pressure at the fuel entrance 75 is higher than the predetermined value, the fuel is supplied to the pilot fuel passage 64 and to the main fuel passage 65.
