Rotary nozzle

摘要

A specialty nozzle is provided having a pattern adjustment valve that may be adjusted to irrigate a substantially rectangular irrigation area. The nozzle may be further adjusted to irrigate two different substantially rectangular irrigation areas. The nozzle functions as a three-in-one left strip nozzle, right strip nozzle, and side strip nozzle. 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 adjustment 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.
