A venturi driven differential injector (20) for fluid mixing having a constricting primary fluid inlet (26), a throat section (27) and a diverging discharge outlet (28). A secondary fluid is pulled into the forward portion of the discharge outlet (28), through at least two annular recessed grooves, by suction action produced by the primary fluid of the venturi. A plurality of channels (32) feed the secondary fluid into the recessed annular grooves. The venturi ports are connected to a secondary fluid injection port (30) via an injection annulus.
La présente invention concerne un injecteur différentiel (20) à venturi destiné au mélange de fluides, qui comprend une entrée convergente (26) de fluide primaire, une gorge (27) et une sortie de déchargement (28) divergente. Un fluide secondaire est attiré dans la partie amont de la sortie de déchargement (28), en passant par au moins deux fentes annulaires encastrées, en raison de la succion provoquée par le fluide primaire du venturi. Un pluralité de canaux (32) permettent d'alimenter en fluide secondaire les fentes annulaires encastrées. Les orifices du venturi sont reliés à un orifice d'injection (30) de fluide secondaire via un canal d'injection.
