Abstract (en)
The injector for delivering fuel to two air inlet ducts (2,3) separated by a partition, is situated between the two ducts and has a skirt (12) which is tubular in shape and located inside the partition. The injector (11) is set at the upper end of the skirt, the lower part of which forms two fuel passages (19) which are in communication with one another inside the skirt and emerge into the two ducts through outlets. In the outlet zone the skirt wall is progressively chamfered towards its free edges (17) and has concave recesses, while the upper end of the skirt is shaped to form a seat (14) for the injector. The skirt is made in one piece with the inlet ducts, with the fuel passages and outlets (20) formed round parallel axes.
