Abstract

INJECTEUR DE CARBURANT ELECTROMAGNETIQUE. IL COMPORTE UN SOLENOIDE 116 QUI COMMANDE UNE SOUPAPE QUI COMPORTE UN OBTURATEUR 159 MONTE COULISSANT DANS L'ALESAGE 148 D'UN CORPS DE SOUPAPE 146. L'OBTURATEUR COMPORTE UN OPERCULE SPHERIQUE 164 RACCORDE PAR UNE TIGE SOUPLE 160 A UNE ARMATURE 162 SUR LAQUELLE AGIT LE SOLENOIDE. L'OPERCULE COOPERE AVEC UN SIEGE CONIQUE 150 DANS LEQUEL A ETE ESTAMPEE UNE SURFACE SPHERIQUE 165 CORRESPONDANTE. UNE CHAMBRE DE TURBULENCE 151 EST FORMEE ENTRE L'INTERFACE OPERCULE-SIEGE ET L'INTERFACE OPERCULE-ALESAGE DANS LAQUELLE DEBOUCHENT DES ORIFICES DE DOSAGE 149A, 149B DONT AU MOINS CERTAINS SONT TANGENTIELS POUR ENGENDRER, LORSQUE LA SOUPAPE EST OUVERTE, UN TOURBILLON DANS LA CHAMBRE DE TURBULENCE, TOURBILLON QUI EST AMPLIFIE PAR LE SIEGE CONIQUE ET DETERMINE EN PARTIE L'ANGLE DE PULVERISATION DE L'INJECTEUR. APPLICATION A UN INJECTEUR A ALIMENTATION BASSE.
