Abstract

L'INJECTEUR COMPORTE UN BOITIER FORME PAR UN CORPS TUBULAIRE 100 FERME PAR DES CAPUCHONS D'EXTREMITE AVANT 106 ET ARRIERE 110. UN CORPS DE BOBINE 114 PORTANT UNE BOBINE 116 EST LOGE DANS LE BOITIER ET COMPORTE UN NOYAU REGLABLE 128 QUI EST VISSE DANS LE CAPUCHON ARRIERE 110 ET QUI COOPERE AVEC UNE ARMATURE 158 A LAQUELLE EST FIXE UN POINTEAU 156 MONTE COULISSANT DANS L'ALESAGE 148 D'UN CORPS DE SOUPAPE 146 POUR OUVRIR UN ORIFICE DE DOSAGE 154. LE POINTEAU EST SOLLICITE EN POSITION FERMEE PAR UN RESSORT DE FERMETURE 137 DONT LA FORCE PEUT ETRE REGLEE AU MOYEN D'UNE VIS DE REGLAGE 132 QUI EST VISSEE DANS LE NOYAU ET QUI AGIT SUR LE RESSORT PAR L'INTERMEDIAIRE D'UNE BILLE 136 POUR EVITER LA TRANSMISSION DES FORCES DE TORSION. APPLICATION AUX INJECTEURS DE MOTEURS A COMBUSTION INTERNE.
