Abstract

Dispositif pour l'obtention d'un mélange air-carburant. Il comporte un gicleur 2 qui pulvérise sous faible pression un jet de carburant dans la zone d'une tuyère d'air comburant du type Laval. Le carburant traverse au moins deux systèmes de mélange 1 successifs, le premier entre la marche au ralenti jusqu'à la demi-charge et le second entre la demi-charge et la pleine charge. Chaque système 1 comporte deux chambres de mélange 19 et 23 successives prolongées chacune par une tuyère ou buse 7, respectivement 8. Le mélange est ainsi finement divisé. Moteurs à combustion interne.
