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.
