Abstract

Official abstract text for this publication.

A fuel injector device for an annular combustion chamber of a turbine engine, including a pilot circuit feeding an injector and a multipoint circuit feeding injection orifices formed in a front face of an annular ring mounted in an annular chamber, together with a thermal insulation mechanism insulating the front face and including an annular cavity formed around the injection orifices between the front face of the annular ring and a front wall of the annular chamber and configured to be filled in operation with air or with coked fuel.

First claim

Opening claim text (preview).

The invention claimed is: 1. A fuel injector device for an annular combustion chamber of a turbine engine, the device comprising: a pilot circuit continuously feeding an injector leading into a first venturi; a multipoint circuit intermittently feeding injection orifices formed in a downstream face of an annular ring mounted in an annular chamber formed at the upstream end of a second venturi coaxially surrounding the first venturi; and thermal insulation means for insulating…
