Abstract
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.
