Rotary variable arc nozzle
Abstract:
A variable arc sprinkler head or nozzle may be set to numerous positions to adjust the arcuate span of the sprinkler. The nozzle may 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.
