Abstract

Le carburateur auxiliaire selon l'invention comprend un moyen principal composé d'une membrane 35, rappelée par un ressort 36, et d'une chambre 37 soumise aux variations de pression qui se produisent dans la tuyauterie en aval d'un robinet 12 thermosensible. Ce moyen principal commande l'ouverture et la fermeture d'un robinet 34 d'alimentation en carburant. Un moyen supplémentaire composé d'une deuxième chambre 40 communiquant avec la première par un étranglement 41, et d'une deuxième membrane 42, réduit automatiquement l'effort total d'ouverture exercé sur la vanne d'alimentation après un temps limité consécutif à une augmentation de pression dans la tuyauterie. Applications : notamment aux moteurs à combustion interne et à allumage par bougies.The auxiliary carburetor according to the invention comprises a main means composed of a membrane 35, biased by a spring 36, and of a chamber 37 subjected to the pressure variations which occur in the piping downstream of a thermosensitive valve 12. This main means controls the opening and closing of a fuel supply valve 34. An additional means composed of a second chamber 40 communicating with the first through a constriction 41, and of a second membrane 42, automatically reduces the total opening force exerted on the supply valve after a limited time following a pressure increase in the piping. Applications: in particular to internal combustion and spark ignition engines.
