Abstract:
1. A method of establishing a vacuum profile in a non-air gap eductor including an inlet port, an outlet port, and a venturi tube disposed between the inlet port and the outlet port, the method comprising: receiving water via the inlet port from a source; directing a first portion of the water along a first flow path extending longitudinally through a first flow guide and a second flow guide of the eductor, the first portion of the water flowing through the venturi tube toward the outlet port; reducing pressure within the eductor along the first flow path in response to the first portion of water flowing through the venturi tube; directing a second portion of the water along a second flow path offset from the first flow path; controlling the amount of water flowing along the second flow path based at least in part upon the position of the second flow guide relative to the first flow guide; and creating a desired vacuum based upon the amount of water directed along the second flow path.
