An eductor apparatus (20) includes a fluid inlet port (30) which directs fluid through an air gap (32) to an eductor (42). A rib (38) deflects any fluid which bounces off of the eductor (42) so that the fluid is retarded from exiting through an air gap port (34). The eductor (42) is of a one-piece construction having a specially designed inlet port (44) and exterior surface (116) thereabout in order to ensure attached flow and thereby reduce the amount of fluid which bounces off the exterior surface (116) and which is directed back upstream toward the air gap port (34).
Un dispositif éjecteur (20) comporte un orifice (30) d'entrée de fluide qui dirige un fluide vers un éjecteur (42), à travers un espace anti-refoulement (32). Une nervure (38) dévie tout fluide qui rebondit sur l'éjecteur (42) de telle sorte que le fluide sort avec un retard par l'orifice (34) de l'espace anti-refoulement. Cet éjecteur (42) est de construction monobloc et possède un orifice d'entrée (44), de conception spéciale, entouré d'une surface externe (116) de façon à assurer que l'écoulement suive ladite surface et à réduire ainsi la quantité de fluide qui rebondit sur la surface externe (116) et est renvoyée vers l'amont en direction de l'orifice (34) de l'espace anti-refoulement.
