Abstract

La présente invention concerne un système d'injection de carburant qui permet d'obtenir une grande sécurité de fonctionnement, tout en étant simple à construire d'un point de vue mécanique et peu complexe à commander. A cette fin, on utilise un dispositif de limitation de débit qui comprend une soupape de limitation de débit et une soupape de dérivation et qui est monté en amont d'un injecteur respectif. L'élément de blocage de ce dispositif de limitation de débit est contraint dans une direction de fermeture avec une force de fermeture qui correspond à la différence de pression sur la soupape de limitation de débit et peut être réglé dans une direction d'ouverture au moyen d'un système de réglage dont la force de réglage est inférieure à la force de fermeture correspondant à la différence de pression qui s'établit sur la soupape de limitation de débit lorsque la soupape d'injection est déréglée, c'est-à-dire lorsque l'alimentation en carburant à la chambre de combustion du cylindre respective dépasse la quantité d'injection de régulation maximale.
