1. A nozzle for dispensing a flow of a fluid, comprising:
a non-rotating longitudinal body having an axis comprising a chamber wall and a flow chamber within the chamber wall, the flow chamber having a fluid entrance end and a fluid exit end, the flow chamber including a flow deflector within the flow chamber, said flow chamber extending from said fluid entrance end to said fluid exit end, said flow chamber having a flow area and a fixed diameter at said fluid exit end, said flow deflector comprising a moveable tapered body, said tapered body longitudinally supported in said flow chamber by a support comprising a web comprising static fins and a central hole adapted to align the tapered body, said web having a plurality of passageways permitting fluid to flow therethrough, said web aligning said tapered body within said flow chamber, said tapered body having a first tapered end converging to a point that is directed to the fluid entrance end of said flow chamber and a second tapered end converging to a point that is directed to the fluid exit end of said flow chamber, said second tapered end having an angle that allows the fluid flowing through the flow chamber to follow along said second tapered end to create a solid stream at said fluid exit end to create a smooth laminar flow of fluid, said first and second tapered ends being directed in opposite directions; a slider disposed in the interior of the longitudinal body that is slideably moveable along the axis of the longitudinal body and that is adapted to travel to a position distally away from said tapered body; and an adjuster associated with the longitudinal body, said adjuster comprising a rotatable end bell and a downstream housing portion, said downstream housing portion rotatable about the longitudinal axis to enable an operator of the nozzle to selectively adjust an amount of flow projected by the nozzle by turning the adjuster, said adjuster rotatably adjustable to move into a position proximate to the web. |
