Patent ID: 8002201

Claim:
A method of adjusting a fluid stream in a nozzle, comprising: providing an adjustable nozzle that has: a nozzle body having a longitudinal central axis, said body having an inlet having a fixed inner diameter and an outlet; a flow chamber between the inlet and the outlet; an elastic water impervious material in fluid communication with said inlet, said material having a tapered end proximate to the fluid outlet; an adjustable tapered non-rusting body having an outlet diameter, said adjustable tapered non-rusting body comprised of numerous, elongated sections extending along said longitudinal central axis, said adjustable tapered non-rusting body adapted to expand or constrict when said tapered body is adjusted in a fashion to either increase or decrease its outlet diameter to enable the nozzle to operate as a selectable smooth bore, said elastic water impervious material having a tapered configuration similar to that of the tapered non-rusting body; a rigid, non-rusting member suitably adapted for connection to a water supply, and initiating a flow of fluid into a fluid inlet associated with said nozzle, the fluid inlet leading to a flow chamber, the flow chamber terminating in a fluid outlet having a variable diameter; and automatically varying the diameter of the outlet in response to variations in a flow rate, wherein the diameter of the outlet is increased in response to increases in the flow rate and the diameter of the outlet is decreased in response decreases in the flow rate; wherein automatically varying the diameter of the outlet substantially maintains the inlet pressure at a predetermined pressure.
