Abstract

L'appareil comprend un dispositif 10 d'écoulement de fluide qui comprend une zone d'entrée convergente 20, un col 22 à section réglable et une zone divergente 24, la section du col étant réglée en fonction des besoins du moteur alimenté en mélange air-combustible par l'appareil et une vitesse d'écoulement sonique étant maintenue dans le col sur la quasi-totalité de la plage de fonctionnement du moteur. Un orifice 34 d'introduction de combustible est formé en amont du col et une tige 36 de dosage et de distribution montée solidaire de la partie mobile 18 du col coulisse dans l'orifice et comporte au moins une paire de fentes longitudinales 40 formées dans sa partie amont et dont la section décroît en éloignement de l'ouverture 34 pour distribuer le combustible le long de la tige dont il est détaché par le courant d'air. Application à l'alimentation des moteurs à combustion interne.
