Abstract

Ce carburateur est commandé par un solénoïde actionné conformément à un cycle de marche modulé par des impulsions de largeur variable et comporte une tige doseuse principale 38 et une soupape 64 de prise d'air de ralenti sollicitées en appui contre une patte 44 portée par l'armature 70 du solénoïde. L'armature est sollicitée par un ressort 72 dans une position de mélange riche, en appui contre une butée réglable 74, et est attirée par la bobine de solénoïde 78 excitée dans une position de mélange pauvre, en appui contre une partie de la bobine 78. Celle-ci est appliquée par un ressort 102 contre une butée réglable 104 pour établir la position de mélange pauvre de la tige doseuse et de la soupape de prise d'air. Application aux carburateurs fonctionnant en boucle fermée pour établir un rapport air-carburant désiré constant.
