Abstract

L'invention concerne un dispositif de carburateur pour un moteur thermique démarrant au moyen d'une commande par câble, comprenant une partie de conduite d'aspiration (9) et une conduite d'alimentation en carburant (8) débouchant dans la partie (9) de la conduite d'aspiration, laquelle conduite d'alimentation en carburant est reliée à un espace (4) formant accumulateur rempli de carburant. Le carburant est aspiré en fonction de la dépression se produisant dans la partie (9) de la conduite d'aspiration. Lors du démarrage, la dépression se produisant dans la partie (9) de la conduite d'aspiration est augmentée avec un dispositif de démarrage (30). Pour maintenir le moteur apte à fonctionner, lorsque le dispositif de démarrage (30) est en fonction, une soupape de commande (40) est disposée entre l'orifice (HA) de la conduite d'alimentation en carburant (8) dans la partie (9) de la conduite d'aspiration, et l'espace (4) formant accumulateur, laquelle soupape de commande est ouverte ou fermée par une unité de commande (41), en fonction du régime du moteur thermique (28).
