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 fuel injector system for a combustor of a gas turbine engine includes first and second fuel injectors (20,22) rendered operative to discharge fuel to the combustor during a high power regime of engine operation and rendered non-operative during a lower power regime of engine operation. The first and second fuel injectors include respective first and second fuel discharge passages (84,86) in fuel flow communication to one another and to the combustor via associated fuel discharge lips (80,82) to sustain a flame region. The first and second fuel injectors are operatively associated with respective first and second air discharge means (100,102) having air discharge lips (110,112) for discharging air to the combustor for sustaining the flame region therein. When the fuel injectors are rendered non-operative during the lower power engine operation regime, different pneumatic pressures established at the fuel discharge lips generate a pressure differential on the fuel residing in the injectors effective to purge the resident fuel from the injectors into the combustor rapidly enough for ignition by the existing flame region in the combustor.
摘要翻译： 用于燃气涡轮发动机的燃烧器的燃料喷射器系统包括第一和第二燃料喷射器（20,22），其在发动机操作的高功率状态期间可操作地将燃料喷射到燃烧器，并且在较低功率状态 发动机运转。 第一和第二燃料喷射器包括各自的第一和第二燃料排放通道（84,86），其燃料通过相关联的燃料排放口（80,82）彼此连通并连接到燃烧器，以维持火焰区域。 第一和第二燃料喷射器与相应的第一和第二空气排放装置（100,102）可操作地相关联，该空气排出装置具有排气口（110,112），用于将空气排放到燃烧室以维持其中的火焰区域。 当燃料喷射器在较低功率发动机运行状态期间变得不起作用时，在燃料排出口处建立的不同的气动压力对驻留在喷射器中的燃料产生压差，有效地将驻留的燃料从喷射器中快速地吹入燃烧器 足以通过燃烧器中的现有火焰区域进行点火。

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 (10) having one or more, preferably two, air discharge orifices (122c) for discharging air to the combustor and first (130) and second (150) 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 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.
