Title (EN) FUEL INJECTION DEVICE WITH RESONANT NEEDLE FOR INTERNAL COMBUSTION ENGINE
(FR) DISPOSITIF D'INJECTION DE FLUIDE A AIGUILLE RESONANTE POUR MOTEUR A COMBUSTION INTERNE
Abstract: front page image
(EN)The invention relates to a fuel injection device with a resonant needle, that comprises a cylindrical body (10), a running part (11) mounted so as to be capable of sliding in the cylindrical body, the needle (110) being part of the running part (11) and having one end including a head (111) defining a valve on a seat (102) carried by one end of the cylindrical body (10). The device further includes an actuator (105) with an electro-active material, and holding means for urging the head (111) against the seat (102). The holding means (130) applies a magnetic force on the running part (11).
(FR)Un dispositif d'injection de fluide à aiguille résonante comporte un corps (10) cylindrique, un équipage mobile (11) monté coulissant dans le corps cylindrique, l'aiguille (110) étant partie de l'équipage mobile (11) et ayant une extrémité comportant une tête (111) formant clapet sur un siège (102) porté par une extrémité du corps (10) cylindrique. Le dispositif comporte en outre un actionneur (105) à matériau électro-actif et des moyens de maintien tendant à mettre la tête (111) en appui contre le siège (102). Les moyens de maintien (130) exercent une force magnétique sur l'équipage mobile (11).
