Abstract

Pompe pour système d'alimentation en carburant d'un moteur à com ustion interne, ce système étant du type dans lequel le carburant est emmagasiné sous pression dans un accumulateur et délivré au moteur par un injecteur dont la période d'ouverture est réglée strictement pour fixer la quantité de carburant fournie au moteur. La pompe alimente l'accumulateur et comprend une pompe haute pression qui est entraînée par le moteur auquel le système d'alimentation est associé, cette pompe haute pression comportant un orifice de sortie relié en fonctionnement à l'accumulateur et un orifice d'entrée relié à une source de carburant, un moyen d'étranglement destiné à régler le débit de carburant à cet orifice d'entrée et un moyen réagissant en fonctionnement à la pression dans l'accumulateur et destiné au réglage de la position du moyen d'étranglement
