Abstract: A nozzle is provided having a low precipitation rate and uniform fluid distribution to a desired arcuate span of coverage. The nozzle has an inflow port having a shape corresponding to the desired arc of coverage and a size for effecting a low precipitation rate. The nozzle also has a deflector surface with a water distribution profile including ribs for subdividing the fluid into multiple sets of fluid streams. There are at least two fluid streams for distant and close-in irrigation to provide relatively uniform distribution and coverage. The nozzle may be a unitary, one-piece, molded nozzle body including a mounting portion, an inflow port, and a deflector portion.

Abstract: Rotary nozzles and deflectors for use with rotary nozzles are provided. The deflector includes a number of flutes that deliver fluid streams radially outwardly from the deflector. Fluid striking the flutes of the deflector cause the deflector to rotate, and the flutes subdivide fluid impacting deflector into multiple fluid streams that are distributed radially outwardly to surrounding terrain as the deflector rotates. Each of the flutes have the same curvature, although they may have different inclinations to distribute fluid streams at different trajectories. The flutes may also include blocking and downward-facing features at the ends of the flutes to improve the evenness of the fluid distribution in the irrigation coverage area.

Abstract: An irrigation nozzle with a rotating deflector is provided whose rotational speed may be controlled by a friction brake. The nozzle may also include an arc adjustment valve having two portions that helically engage each other to define an opening that may be adjusted at the top of the sprinkler to a desired arcuate length. The arcuate length may be adjusted by pressing down and rotating a deflector to directly actuate the valve. The nozzle may also include a radius reduction valve that may be adjusted by actuation of an outer wall of the nozzle. Rotation of the outer wall causes a flow control member to move axially to or away from an inlet.
