Abstract
Cet éjecteur bi-étagé comprend un corps (16) comportant : - une entrée d'air comprimé (E) ; - une buse (17) d'injection d'air comprimé placée en aval de l'entrée d'air ; - une conduite centrale (18) ; et - un mélangeur de sortie (19). La buse d'injection (17), la conduite centrale (18) et le mélangeur de sortie (19) sont disposés suivant un axe (X-X') de l'éjecteur de sorte que les extrémités de la conduite axiale soient respectivement espacées de la buse et du mélangeur de manière à former une première et une deuxième zone d'aspiration (23, 25) qui communiquent avec une unique chambre d'aspiration d'air (21) commune.
