Abstract

A jet pump comprising (A) a housing which defines at least a suction chamber, a suction inlet and a suction outlet; (B) a nozzle assembly disposed within the housing which nozzle assembly is sized and configured to receive at least a pressurized fluid and eject the pressurized fluid as a fluid flow into a portion of the suction chamber; and (C) a discharge conduit extending from the suction outlet away from the suction chamber, the discharge conduit being configured for fluid communication with the suction chamber and being disposed to receive the fluid flow from the nozzle assembly, wherein the discharge conduit defines at least a first inner diameter along a portion of its length and a second inner diameter along another portion of its length, the first inner diameter being less than the second inner diameter. The housing is configured so that the suction inlet provides a flow of suctioned material into the suction chamber which has a predominant direction of flow of suctioned material which is substantially parallel to a predominant direction of flow of the fluid flow from the nozzle assembly when the jet pump is in use.
