A system for injecting an air/fuel mixture into a combustion chamber of a turbomachine, the system having an injector comprising: an axial internal volume opening out at one end via an axial outlet for the air/fuel mixture; a first fuel feed stage having a plurality of first fuel feed orifices which open out into the internal volume, which are distributed around an axis of the injector, and which are connected by fuel feed channels to an inlet for admitting fuel into the injector; and at least one air feed channel which opens out into the internal volume and which is connected to an inlet for admitting air into the injector. The injector further comprises at least one second fuel feed stage with a plurality of second fuel feed orifices which open out into the internal volume, which are distributed around the axis of the injector, and which are connected to said inlet for admitting fuel into the injector via fuel feed channels which coincide at least in part with the fuel feed channels of said first stage.
