Abstract

L'injecteur comporte une aiguille coulissant axialement dans un corps d'injecteur et décollant de son siège sous l'effet de la pression du combustible, et s'engageant au moins pendant une partie de sa course, en dessous de son siège par un téton d'étranglement, dans un alésage central. Ce téton d'étranglement a au moins une surface de distribution 5 ou un méplat, conçus de telle manière que la direction et/ou la caractéristique du jet de combustible changent en fonction de la course d'aiguille. On obtient un jet de combustible bien adapté au régime du moteur, ralenti ou rapide, faible ou forte charge. L'invention s'applique aux injecteurs de moteurs à combustion interne, notamment diesel.
