Abstract

LA PRESENTE INVENTION CONCERNE UN SYSTEME D'ADMISSION DE MOTEUR A EXPLOSION COMPORTANT UN CARBURATEUR A DEUX CORPS. LE SYSTEME COMPREND UN PREMIER CANAL D'ADMISSION 46 QUI S'ETEND ENTRE LE CORPS PRIMAIRE 18 DU CARBURATEUR ET UNE CHAMBRE DE COMBUSTION 16, ET UN SECOND CANAL D'ADMISSION 47 QUI S'ETEND ENTRE LE CORPS SECONDAIRE 19 DU CARBURATEUR ET LA MEME CHAMBRE DE COMBUSTION. LES PAPILLONS 21, 22 DES CORPS PRIMAIRE ET SECONDAIRE COMMANDENT, RESPECTIVEMENT, LE DEBIT DANS LES PREMIER ET SECOND CANAUX D'ADMISSION. AINSI, AUX FAIBLES CHARGES ET AU RALENTI, LA CIRCULATION DU MELANGE JUSQU'A LA CHAMBRE DE COMBUSTION NE SE FERA SENSIBLEMENT QUE PAR LE PREMIER CANAL D'ADMISSION DE FACON A AUGMENTER LA VITESSE ET A AMELIORER LE FONCTIONNEMENT DU MOTEUR. UNE SOUPAPE D'ADMISSION SEPAREE EST PLACEE A L'EXTREMITE DE DECHARGE DE CHACUN DES CANAUX D'ADMISSION, ET CES SOUPAPES SONT ACTIONNEES SIMULTANEMENT PAR LE LOBE COMMUN D'UNE CAME 32 DE L'ARBRE A CAMES 33.
