摘要： A self-purging fuel injector for a combustor of a gas turbine engine is disclosed wherein the fuel injector comprises an injector body having one or more, preferably two, air discharge orifices for discharging air to the combustor and first and second fuel passage means having respective first and second fuel discharge orifices for discharging fuel to the combustor. The first and second fuel passages are in communication upstream of the fuel discharge orifices. If the supply of fuel to the first and second fuel discharge orifices is interrupted, a pneumatic pressure is applied at the first fuel discharge orifice and a different pneumatic pressure is applied at the second fuel discharge orifice such that the fuel residing in the fuel passages between the first and second fuel discharge orifices is subjected to a pressure differential effective to purge the resident fuel into the combustor.

摘要： A self-purging fuel injector (10) for a combustor (C) of a gas turbine engine wherein the fuel injector comprises an injector body having first (122c) and second (142c) air discharge orifices for discharging air to the combustor and first (130,132) and second (150,163,162) fuel passage means having respective first (132c) and second (162c) fuel discharge orifices for discharging fuel to the combustor. The first and second fuel passages are in communication upstream (70,64,72) of the fuel discharge orifices. The first air and fuel discharge orifices have a relationship to establish a pneumatic pressure at the first fuel discharge orifice and the second air and fuel discharge orifices have a relationship to establish a different pneumatic pressure at the second fuel discharge orifice such that, in the event the supply of fuel to the first and second fuel discharge orifices is interrupted, the fuel residing in the fuel passages between the first and second fuel discharge orifices is subjected to a pressure differential effective to purge the resident fuel into the combustor.
