Abstract

Le régulateur de pression est constitué par un boîtier métallique 1 dont la cavité intérieure est divisée par une membrane en deux chambres 21, 23 dont la première, délimitée partiellement par la première face de la membrane, communique avec le collecteur d'aspiration au moyen de la conduite 6 et dont la seconde communique avec une pompe par l'intermédiaire de la conduite 7, à l'entrée de laquelle agit un obturateur 51 pour en faire varier la section. Ce régulateur est caractérisé en ce que l'obturateur 51 a une surface hémisphérique d'articulation en vue de maintenir le parallélisme des surfaces planes d'obturation, afin d'assurer le retour d'excès de carburant vers le réservoir.
