Abstract
LA PRESENTE INVENTION CONCERNE UN DISPOSITIF D'INJECTION DE CARBURANT POUR MOTEUR A COMBUSTION INTERNE. DANS CETTE INSTALLATION, ON A PREVU UN TUBE D'ASPIRATION 1 CONTENANT UN PAPILLON 2 ET UN ORGANE DE MESURE 3 MONTE PIVOTANT ET COMMANDANT UNE SOUPAPE DE DOSAGE DE CARBURANT 7. ON A PREVU DES SOUPAPES A MEMBRANE 11. UNE SOUPAPE DE REGLAGE DE PRESSION DIFFERENTIELLE 20 EST DIVISEE EN DEUX CHAMBRES 22 ET 23 PAR UNE MEMBRANE 21. LA MEMBRANE 21 EST SOUMISE SUR CHACUNE DE SES FACES, A LA PRESSION DE RESSORTS 34, 36, 54 DONT LA TENSION EST REGLEE EN FONCTION DES PARAMETRES DE FONCTIONNEMENT DU MOTEUR. L'INVENTION PERMET UN MEILLEUR DOSAGE DE CARBURANT POUR CHAQUE ETAT DE FONCTIONNEMENT DES MOTEURS A COMBUSTION INTERNE.
