Title
(EN) ROTOR CARBURETTOR FOR STARTING AND OPERATING AN INTERNAL COMBUSTION ENGINE, EVEN WITH HIGH FUEL TEMPERATURES
(FR) CARBURATEUR A ROTOR POUR METTRE EN MARCHE ET FAIRE FONCTIONNER UN MOTEUR A COMBUSTION INTERNE, MEME EN CAS DE TEMPERATURES DE CARBURANT ELEVEES
Abstract
(EN)
The single fuel outlet opening (17) arranged laterally on the rotor body (2) of the rotor carburettor is connected to the exhaust opening (11) of the fixed fuel supply pipe (10) coaxial with respect to the rotation axis of the rotor (8) by a fuel feed channel (19, 20), the medial line thereof and the rotation axis (8) being in the same plane. The fuel feed channel (19, 20) is provided with an inlet opening (21) coaxial with respect to the exhaust opening (11) and a skewed inlet section (20) downstream of the inlet opening (21) and diverging to the side of the fuel outlet port (17) of the rotation axis (8). Only a very small portion of the inlet section (20) of which the diameter is smaller than the internal diameter of the supply pipe (10), is arranged on the side of the rotation axis (8) which is diverted from the fuel outlet port. The other sections (19a, 19b, 19c) of the fuel feed channel connected to the inlet section (20) have all a diameter which is larger than the diameter of the inlet section (20). The skewed inlet section (20) replaces the cylindrical fuel chamber which is coaxial with respect to the rotation axis of the rotor and which is found in known rotor carburettors and ensures, even if the fuel temperature is 80oC, an effortless starting as well as a continuous operation of an internal combustion engine provided with such a rotor carburettor.
(FR)
L'unique trou de sortie de carburant (17) disposé latéralement sur le corps de rotor (2) du carburateur à rotor est raccordé à l'ouverture d'échappement (11) du tuyau d'alimentation en carburant (10) fixe et coaxial par rapport à l'axe de rotation du rotor (8) par un canal d'amenée de carburant (19, 20), sa ligne médiane et l'axe de rotation (8) se trouvant dans le même plan. Le canal d'amenée de carburant (19, 20) possède une ouverture d'entrée (21) coaxiale par rapport à l'ouverture d'échappement (11) et une section d'entrée oblique (20) en aval de l'ouverture d'entrée (21) et s'écartant sur le côté du trou de sortie de carburant (17) de l'axe de rotation (8). Seule une toute petite partie de la section d'entrée (20), dont le diamètre est inférieur au diamètre intérieur du tuyau d'alimentation (10), se trouve sur le côté de l'axe de rotation (8) qui est détourné du trou de sortie du carburant. Les autres sections (19a, 19b, 19c) du canal d'amenée se raccordant à la section d'entrée (20) sont toutes d'un diamètre supérieur par rapport à la section d'entrée (20). La section d'entrée oblique (20) remplace la chambre de carburant cylindrique et coaxiale par rapport à l'axe de rotation du rotor que l'on trouve dans les carburateurs à rotor connus et garantit, même si la température du carburant est de 80oC, une mise en marche sans peine ainsi qu'un fonctionnement sans interruption d'un moteur à combustion interne doté d'un tel carburateur à rotor.
