Abstract:
1. An adjustable nozzle comprising: a longitudinal nozzle body extending from a fluid inlet to a fluid outlet, such that said nozzle body defines a central axis, said nozzle body configured to receive a pressurized fluid at said fluid inlet and discharge the pressurized fluid at said fluid outlet said nozzle body having an upstream cylindrical portion and a downstream tapered portion integrally formed with the cylindrical portion; and a flexible membrane disposed within said longitudinal nozzle body and having an upstream end proximate said cylindrical portion and in fluid communication with said fluid inlet of said nozzle body and a downstream end proximate said tapered portion and in fluid communication with said fluid outlet of said nozzle body, at least a portion of said flexible membrane having a tapered inner profile, such that a downstream portion of said flexible membrane has a smaller diameter as compared to an upstream portion of said flexible membrane when said nozzle body is devoid of the pressurized fluid, said downstream portion of said flexible membrane spaced from said nozzle body, such that said downstream portion is expandable when said nozzle body receives the pressurized fluid at said fluid inlet and is contractable when said nozzle body is devoid of the pressurized fluid.
