Abstract

Une telle soupape est destinée à maintenir constante la différence de pression entre la tuyauterie d'admission du moteur et la pression d'alimentation des injecteurs. Une soupape selon l'invention travaille avec une plus grande précision que des soupapes connues grâce à l'utilisation d'un ressort de traction 13 réglable dispose dans une chambre Il. Ce ressort agit sur un clapet 10, porté par un diaphragme 3, dans le sens de la fermeture d'un passage 9, par lequel la chambre 5 communique à travers la chambre Il avec une décharge 12 (renvoi au réservoir de carburant excédentaire) lorsqu'une augmentation de la pression de carburant dans la chambre 5 repousse le diaphragme 3 davantage dans la chambre 4, laquelle est reliée à la tuyauterie d'admission du moteur.
