Abstract: An aspirator with an aspirator body and an exhaust port coupled to the body, and having a plurality of integral high pressure gas nozzles positioned along the aspirator body the body. The aspirator body includes a high pressure integral conduit in communication with a nozzle array having a plurality of high pressure gas nozzles. The nozzles are arcuate, extending away from the body toward an aspirator centerline, the nozzles extending from the aspirator body at a preselected angle toward the centerline in a direction from an atmospheric air aspiration port toward the exhaust port. A high pressure inlet port integral with the body is in communication with the conduit and a high pressure gas source. The gas may be input into the inlet port using a high pressure inlet fitting, which may be threaded onto the inlet port outside the aspirator body. The aspirator is fabricated by additive manufacturing techniques.
