Abstract

Dispositif pour moteur qui comprend une arrivée d'air avec un conduit principal et un deuxième conduit de plus faible section. Il comprend des premiers moyens de distribution d1 du combustible dans le conduit principal 7; des seconds moyens de distribution d2 du combustible dans le conduit auxiliaire 8 et des moyens de répartition du débit entre les deux conduits agencés de façon qu'à faible puissance, seul le conduit auxiliaire soit alimenté en combustible. Application aux moteurs présentant un recouvrement entre l'admission et l'échappement.
