Abstract

Dispositif comprenant un circuit à gicleur d'enrichissement avec lequel coopère un obturateur commandé par l'intermédiaire d'une tige de commande soumise aux actions opposées d'un ressort tendant à assurer l'ouverture du circuit précité et de la dépression à l'admission du moteur tendant à laisser s'effectuer la fermeture dudit circuit à partir d'une valeur prédéterminée, caractérisé en ce que la tige de commande est liée à une partie constitutive d'une capacité à volume variable immergée dans la cuve du carburateur et présentant au moins un orifice de communication avec l'essence environnante, tandis qu'une autre partie constitutive de ladite capacité coopère avec ledit obturateur ainsi qu'avec un ressort tendant à s'opposer à l'ouverture de l'obturateur par cette autre partie et à réduire le volume de ladite capacité variable pour n'autoriser qu'une ouverture temporisée dudit obturateur.
