Claim Text:
1. An adjustable fluid nozzle, comprising: a longitudinal nozzle body extending from an inlet to an outlet, such that said nozzle body defines a central axis, said nozzle body configured to receive pressurized fluid at said inlet and discharge the pressurized fluid at said outlet; a flexible membrane comprised of an elastic water impervious material disposed within said longitudinal nozzle body and having an upstream end in fluid communication with said inlet of said nozzle body and a downstream end in fluid communication with said outlet of said nozzle body, said flexible membrane having a tapered profile and adapted to expand when said nozzle body receives the pressurized fluid, 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 being expandable when said nozzle body receives the pressurized fluid at said water inlet and being contractable when said nozzle body is devoid of the pressurized fluid, wherein said flexible membrane has a smooth inner surface; wherein said nozzle body comprises a plurality of adjacent springy, non-rusting, members extending along the longitudinal central axis that contact said elastic water impervious material when said nozzle body receives pressurized fluid, said springy members having spaces therebetween and devoid of separate sealing elements connecting said springy members, said springy members adapted to form a tapered portion of said nozzle body, said tapered portion having a taper that matches the taper of said flexible membrane.
