Abstract

Dispositif d'injection de carburant pour moteur à combustion interne. Le dispositif d'injection de carburant pour moteur à combustion interne, du type comprend une tête d'injection solidaire de l'extrémité d'une aiguille (3) mobile en translation à l'intérieur d'un boîtier d'injection (4) alimenté en carburant à haute pression et présentant un siège pour la tête d'injection, et un élément vibratoire (5) piézoélectrique ou magnétostrictif capable, lorsqu'il est excité, d'agir sur l'aiguille (3), maintenue par un ressort de rappel (10), pour la mettre en vibration, de façon que la tête d'injection coopère avec son siège pour ouvrir et fermer périodiquement un passage d'injection du carburant. Le dispositif comprend un moyen de commande (16, 17) de déplacement de l'aiguille par translation, à l'encontre du ressort de rappel (10), indépendant de l'élément vibratoire (5).
