Abstract

a. Procédé pour ajuster la course d'ouverture d'une buse d'injection de carburant, et buse d'injection pour la mise en oeuvre de ce procédé. b. Procéde caractérisé en ce que la pression de commande variable est appliquée au tiroir, pour la formation de l'avant-butée, à au moins deux niveaux définis, et est fournie, en même temps, à un élément de poussée qui est en liaison fonctionnelle avec l'aiguille de soupape, de façon telle que la course d'ouverture libre de l'aiguille de soupape est déterminée par le rapport entre la pression de commande, fournie au système, et la pression du carburant fourni, après que l'avant-butée mécanique air été écartée par le tiroir. c. L'invention s'applique notamment aux moteurs Diesel.at. Method for adjusting the opening stroke of a fuel injection nozzle, and injection nozzle for implementing this method. b. Method characterized in that the variable control pressure is applied to the spool, for the formation of the front stop, at at least two defined levels, and is supplied, at the same time, to a pushing element which is in operative connection with the valve needle, so that the free opening stroke of the valve needle is determined by the ratio between the control pressure, supplied to the system, and the pressure of the fuel supplied, after the front -Mechanical air stopper moved away by the drawer. vs. The invention applies in particular to diesel engines.
