Abstract

L'invention concerne un régulateur du rapport air-carburant pour un moteur à combustion interne. Selon l'invention, il comprend un passage d'air 7 conduisant du passage d'admission 9 en amont du pavillon-valve 8 dans le carburateur au passage d'admission 10 en aval, une vanne de contrôle il ouvrant et fermant le passage 7, un moyen 13 sensible à une différence de pression pour déplacer la vanne il, comprenant une membrane flexible 14 entre deux chambres à dépression 15 et 16, un ressort 17 sollicitant la vanne 11 vers la fermeture, un passage 24 communiquant avec la chambre 15 directement et avec l'autre par un orifice 20 et un clapet 18 en parallèle et ouvrant dans le passage 10 en aval du papillon, un passage 25 conduisant de la chambre 16 à l'atmosphère et un moyen 26 de contrôle de vanne fixé au passage 25 pour accomplir l'ouverture et la fermeture selon des conditions spécifiques de fonctionnement du moteur. L'invention s'applique notamment à l'industrie automobile.
