Abstract

Carburateur comportant une pompe de reprise dont la chambre de volume variable est reliée à une cuve à niveau constant par un clapet d'aspiration 11 et au conduit d'admission 1 par un clapet de refoulement Un organe mobile de pompage 15 limitant la chambre à volume variable 9 est actionné en réponse à l'ouverture du papillon 2. La chambre de volume variable est egalement délimitée par un organe complémentaire de pompage 17 qui est soumis à la dépression qui règne en aval du papillon uniquement lorsque la température est inférieure à une valeur déterminée. Application aux moteurs à combustion interne
