Abstract

L'invention concerne un injecteur comportant une aiguille montée dans une buse et présentant une extrémité définissant un clapet, l'aiguille étant, à l'opposé, liée à un actionneur comportant une première, une deuxième et une troisième parties, les première et troisième parties étant disposées de part et d'autre de la deuxième partie, les trois parties étant serrées ensemble pour former un bloc présentant axialement deux limites opposées, la première partie étant liée avec l'aiguille à l'endroit d'une des dites limites, des moyens d'excitation pour mettre la deuxième partie en vibrations avec une période de consigne τ. Selon l'invention, la longueur entre les deux limites du bloc est telle que le temps de propagation T des ondes acoustiques initiées par les vibrations de la deuxième partie de l'actionneur parcourant cette longueur répond à l'équation : T = n*[τ/2], où n est un coefficient multiplicateur, entier positif non nul.
