Abstract
LA PRESENTE INVENTION A POUR OBJET DES INJECTEURS ELECTROMAGNETIQUES ET DES PROCEDES DE FABRICATION DE CEUX-CI. UN INJECTEUR ELECTROMAGNETIQUE SELON L'INVENTION COMPORTE UN CORPS CREUX EN TROIS PARTIES 1, 7 ET 5, ASSEMBLEES PAR UNE ENVELOPPE DE SERTISSAGE 9, UNE BOBINE 10, UN EMBOUT 14, 14A, UNE AIGUILLE D'INJECTION 11 TERMINEE PAR UN POINTEAU 12 QUI S'APPUIE SUR UN SIEGE CONVERGENT 2. L'AIGUILLE COULISSE DANS UNE BAGUE DE GUIDAGE 31 COMPORTANT UNE RAINURE LONGITUDINALE 29. LE SIEGE EST OBTENU PAR MATRICAGE AU MOYEN DE POINCONS. L'USINAGE DE LA BUTEE 18 CONTRE LAQUELLE LA MASSE POLAIRE 13 VIENT EN APPUI EST EFFECTUE AVEC UNE GRANDE PRECISION. UNE APPLICATION EST LA FABRICATION EN SERIE DE LOTS D'INJECTEURS DESTINES A L'INJECTION ELECTRONIQUE DIRECTE OU INDIRECTE DE COMBUSTIBLE DANS UN MOTEUR THERMIQUE.
