Title (EN) A CARBURETTOR OF THE DIAPHRAGM TYPE
(FR) CARBURATEUR DE TYPE CARBURATEUR A DIAPHRAGME
Abstract: front page image
(EN)The present invention relates ta a diaphragm carburettor, more paricularly for two-stroke motors with a carburettor casing (10) having a mixing passage (12) which at its inlet side (38) is connected to an air filter, and a measuring chamber arranged in the casing, said measuring chamber being partitioned into a fuel chamber (22) and a compensation chamber (30) separated by a control diaphragm (24), whereby air is sucked in from the inlet side (38) and fuel being sucked in from the fuel chamber (22) into the mixing passage (12), that the compensating chamber (30) is closed to the surrounding atmosphere but connected to a channel (32) the opening of which (36) enters into the space between the air filter and the fuel inlet (28) in the mixing passage (12). The invention is characterised in that said channel (32) is arranged in a rotation-controlled pipe (33) which can be assembled from outside, said pipe extending through the carburettor casing (10).
(FR)Cette invention se rapporte à un carburateur à diaphragme, conçu particulièrement pour les moteurs à deux temps, qui comporte un carter (10) muni d'un passage de mélange (12) relié à un filtre à air du côté de son orifice d'admission (38) et d'une chambre de mesure, ladite chambre de mesure étant divisée en une chambre à carburant (22) et une chambre de compensation (30) séparées par un diaphragme de régulation (24). Dans ce carburateur, l'air est aspiré du côté de l'orifice d'admission (38) et le carburant est aspiré de la chambre à carburant (22) vers le passage de mélange (12), de telle sorte que la chambre de compensation est fermée à l'atmosphère environnante mais reliée à un canal (32) dont l'ouverture (36) débouche à l'intérieur de l'espace existant entre le filtre à air et l'orifice d'admission (28) du carburant dans le passage de mélange (12). L'invention se caractérise en ce que ledit canal (32) est disposé dans un tuyau à rotation commandée (33) qui peut être assemblé de l'extérieur, ledit tuyau dépassant du carter du carburateur (10).
