Abstract

Appareil de pompage pour l'injection de combustible comprenant un distributeur rotatif muni d'un alésage transversal 12 dans lequel coulissent des pistons 13, et une bague-came 18 entourant le distributeur, qui comporte des lobes de came 19a répartis autour de sa périphérie intérieure. Selon l'invention, pour permettre l'alimentation d'un moteur à cinq cylindres, il est prevu cinq lobes de came régulièrement espaces, un premier galet 20 porté par un patin 19 agissant sur l'un des pistons, l'autre piston étant en contact avec un organe 26 qui s'étend transversalement à l'axe du piston et est actionné par deux galets 24 écartés d'une distance telle qu'ils sont attaqués simultanément par deux lobes de came adjacents.
