MULTI-POINT INJECTOR FOR A TURBINE ENGINE COMBUSTION CHAMBER

摘要

The invention relates to a fuel injection device (67) for an annular combustion chamber, comprising a pilot circuit supplying an injector (16) and a multi-point circuit supplying injection ports (80) formed in a front face (68) of an annular chamber (70), a ring (76) being mounted in the annular chamber (70) in order to define therein a circuit for supplying fuel to the injection ports (80) and a cooling circuit through which the fuel supplying the injector (16) passes and which extends on the front face (68) of the chamber (70) immediately next to the injection ports (80).
