Abstract
LA PRESENTE INVENTION CONCERNE UNE INSTALLATION D'INJECTION DE CARBURANT POUR UN MOTEUR A COMBUSTION INTERNE. LE MOTEUR COMPREND UN TUBE D'ASPIRATION 1 CONTENANT UN PAPILLON 2 ET UNE PLAQUE DE RETENUE 3 DEPLACEE EN FONCTION DE LA QUANTITE D'AIR QUI S'ECOULE ET AGISSANT SUR UNE SOUPAPE DE DOSAGE DE CARBURANT 7. UNE SOUPAPE DE REGLAGE DE PRESSION DIFFERENTIELLE 17 EST DIVISEE EN DEUX CHAMBRES 19 ET 20 PAR UNE MEMBRANE 18 SOLLICITEE SUR SON COTE TOURNE VERS LA CHAMBRE 20 PAR DEUX RESSORTS 33, 34 DE FORCE DIFFERENTE. LE RESSORT LE PLUS FORT S'APPUIE DIRECTEMENT SUR LA MEMBRANE 18 ALORS QUE LE SECOND RESSORT 34, FORMANT RESSORT DE BUTEE ET PLUS FAIBLE, SERT A AMENER LE CORPS DE SOUPAPE 36 QUI TRAVERSE LA CHAMBRE 20, AU CONTACT DE LA MEMBRANE 18. L'INVENTION S'APPLIQUE AUX MOTEURS A COMBUSTION INTERNE DES VEHICULES AUTOMOBILES.
