Beschreibung
Zusammenfassung:	A fuel injector system for injecting fuel into a turbomachine combustion chamber, the system comprising first and second fuel injectors wherein the first injector ( 22 ) is positioned in the center of the injector system ( 20 ) so as to inject a first fuel spray ( 42 ), and wherein the second injector ( 28 ) surrounds the first injector in such a manner as to inject a second fuel spray ( 48 ) of generally annular shape around the first fuel spray. The injector system further comprises an air admission duct ( 22 ) with outlet orifices ( 62 ) opening out between the first and second injectors so as to create a separator air film (f 1 ) between the respective combustion zones of the first and second fuel sprays.
