    摘要： A fuel injector has a metering valve arranged to open under a predetermined feed pressure which constitutes a first threshold pressure, and to remain open in response to said feed pressure increasing so as to deliver fuel to fuel utilization means. The flow rate of fuel passing through the injector is metered to feed said utilization means so long as the feed pressure remains below a second threshold pressure greater than the first threshold pressure. Above the second threshold pressure, the metering valve behaves like a fixed diaphragm as a function of the fluid flow sections formed therethrough. Individual adjustment means are provided so as to enable said second threshold pressure to be adjusted for each injector to ensure that fuel is injected at a uniform flow rate by all of the injectors in a combustion chamber.

    摘要： An injector of a two-headed combustion chamber of a turbomachine has a first feed tube which is connected to an annular injection piece for discharging primary fuel into the combustion chamber. It also has a second feed tube surrounding the first feed tube and connected to a cylindrical endpiece for discharging secondary fuel into said combustion chamber. This endpiece has an annular channel of diameter that is greater than the diameter of the second feed tube and that extends over its entire length. A third tube is provided that surrounds the second tube and that is connected to a tubular separation element which is inserted in the annular channel of the cylindrical endpiece so as to form two annular spaces in which a cooling fluid can flow over 360° all the way to the end of the injector.
