Abstract

L'invention concerne une unité de dosage et de répartition de carburant (10) qui comporte notamment un tiroir (20) et un jeu de fentes (41) configurés avec des géométries, dimensions et positions telles que : - dans une première plage de déplacement du tiroir, la section de passage (31) qui alimente le port de sortie de la rampe de démarrage est ouverte progressivement avec le déplacement du tiroir (20), tandis que la section (41) du jeu de fentes qui alimente le port de sortie de la rampe principale est fermée, - puis, dans une seconde plage de déplacement du tiroir (20), la section (41) du jeu de fentes qui alimente le port de sortie (42) de la rampe principale est ouverte progressivement avec le déplacement du tiroir, tandis que la section de passage (31) qui alimente le port de sortie de la rampe de démarrage est maintenue ouverte.
