Abstract
La pompe selon l'invention comporte un corps de pompe 1 ayant un alésage contenant un élément distributeur rotatif 3 dans lequel peuvent coulisser des pistons opposés 5 commandés par une came annulaire 6 à partir du moteur, de façon que, pour chaque tour du distributeur, la pompe envoie dans chaque cylindre une injection principale de carburant à la fin de la course de compression, précédée par une préinjection. Quand la vitesse du moteur augmente, la course de la pompe est augmentée automatiquement et l'angle entre les sorties des deux passages de sortie est tel que la vitesse du moteur fasse varier le rapport de la préinjection à l'injection principale en fonction du type du moteur (chambre de précombustion ou injection directe).
