Abstract
Le carburateur comporte un corps évidé 3 qui forme un conduit d'aspiration 5 où se trouve un gicleur 6 pour injecter un combustible 10 dans le conduit d'aspiration 1 raccordé à une chambre de mélange 4 située en amont d'un papillon d'étranglement 2. En amont du gicleur 6, une chambre de réchauffage 7 a une paroi 8 qui constitue une surface d'échange thermique pour réchauffer le combustible 10 circulant sous une chemise externe 9. La chambre de mélange 7 est montée axialement dans le conduit d'aspiration 5. Sa paroi 8 est entourée par un dispositif de circulation du combustible, qui présente un profil externe coopérant avec celui du conduit d'aspiration, pour réaliser un passage annulaire 5 aboutissant à la chambre de mélange 4 en convergeant vers l'axe du conduit d'aspiration 1. Le gicleur 6 est constitué par une fente annulaire disposée au voisinage du raccordement convergent précité. Application aux carburateurs, pour en améliorer le réchauffage et en réduire l'encombrement
