Abstract
Les conduits d'injection de carburant dans un dispositif multipoint entourant un dispositif d'injection central dit pilote comprennent des tubes (15) d'orientation circonférentielle. En séparant les conduits d'injection les uns des autres, on peut leur attribuer des pertes de charge différentes qui compensent les différences de longueur que le carburant doit parcourir : un débit uniforme de carburant peut être espéré à chacun des trous d'injection (16). Les tubes sont individuels mais jointifs pour former une couronne (6) unitaire ou composée de deux portions unitaires presque symétriques, qui se prête bien à une fabrication par addition de matière.
