Abstract

DISPOSITIF DE REPARTITION D'UN MELANGE CARBURE DANS UN CARBURATEUR DOUBLE CORPS. ON DISPOSE UN VOLET DEFLECTEUR MOBILE EN ROTATION EN AVAL DE LA VEINE DU MELANGE ET SOUS LE PREMIER CORPS DU CARBURATEUR, COMMANDE PAR LE PAPILLON DU DEUXIEME CORPS, RAMENANT AINSI LE CENTRE DE GRAVITE DE LA CHARGE CARBUREE DANS SA POSITION OPTIMALE, QUELLE QUE SOIT LA POSITION RESPECTIVE DES DEUX PAPILLONS. APPLICATION AUX CARBURATEURS DOUBLE CORPS.DEVICE FOR DISTRIBUTION OF A CARBIDE MIXTURE IN A DOUBLE BODY CARBURETOR. A MOBILE DEFLECTOR FLAP IS AVAILABLE IN ROTATION DOWNSTREAM OF THE MIXTURE VEIN AND UNDER THE FIRST BODY OF THE CARBURETOR, CONTROLLED BY THE THROTTLE OF THE SECOND BODY, THUS RETURNING THE CENTER OF GRAVITY OF THE CARBIDE LOAD TO ITS OPTIMAL POSITION, WHATEVER THE RESPECTIVE POSITION OF THE TWO BUTTERFLIES. APPLICATION TO DUAL BODY CARBURETORS.
