Abstract

Linvention concerne un dispositif assurant un équilibre du mélange air-carburant fourni à un moteur quel que soit le régime du moteur, en particulier à régime élevé, en accélération et en décélération. Dans la gorge 9 de la bride interposée entre le carburateur et l'admission au moteur débouche un conduit 15-17 d'arrivée d'air supplémentaire dont le débit est commandé par un obturateur 18 sous l'action d'une capsule à dépression 24 soumise par un conduit 25 à la dépression en aval du volet du carburateur. Toute augmentation de la dépression en aval du volet du carburateur entraîne l'ouverture du pointeau 20 de l'obturateur 18 et l'envoi de puissants jets d'air dans l'ouverture centrale 4 de la bride 3. Le dispositif est utilisable en étant associé à tous dispositifs connus d'homogénéisation ou de stratification du mélange air-carburant alimentant un moteur à explosion, en particulier pour véhicule automobile.
