Abstract

Appareil de pompage pour l'alimentation d'un moteur à com ustion interne, comprenant une pompe d'injection 15 recevant du combustible d'une pompe d'alimentation 16 sous la commande d'un organe d'étranglement 17 réglable par l'opérateur. Une soupape est montée entre l'organe d'étranglement et la pompe d'injection et comprend un obturateur 30 soumis à la pression de sortie de la pompe d'alimentation et qui agit pour réduire le débit de combustible entre l'organe d'étranglement et la pompe d'injection. L'effet d'étranglement exercé par l'obturateur 30 diminue lorsque la pression de sortie de la pompe d'alimentation augmente. La force exercée par le ressort 35 sur l'obturateur 30 est déterminée par un dispositif sensible à la pression de l'air fourni au moteur associé, agencé pour que l'effet d'étranglement exercé par l'obturateur diminue lorsque la pression d'air augmente. Application aux moteurs suralimentés.
