Abstract

Injecteur-pompe équipé d'un piston plongeur commandé, mécaniquement et délimitant une chambre de pompage, raccordée à un canal d'admission, par lequel le carburant est amené à une aiguille d'injection montée sur le corps d'injecteurs; cet injecteur-pompe comporte par ailleurs un canal de retour d'huile de fuite et un dispositif de commande agissant sur la distribution du carburant. Sur le trajet du canal d'admission 12 est disposé, en amont de la chambre de pompage 3 un clapet 10 actionné suivant la loi le cycle du moteur, clapet coupant la communication entre le canal d'admission 12 et la chambre de pompage 3 lorsque la pression du carburant augmente et qui quitte sa position de fermeture à l'ouverture d'un canal d'évacuation 17 conduisant au canal de retour 14.
