摘要：
A 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 three different substantially rectangular irrigation areas. A variable arc nozzle is also provided that includes an arc adjustment valve having elements that cooperate with one another to adjust the valve between a minimum arc position and a maximum arc position. Further, a variable arc nozzle is provided that includes an arc adjustment valve having a segmented valve body with segments of different axial lengths. The valve settings may be selected by pressing down and rotating a deflector to directly actuate the valve. Each nozzle may also include a flow 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.
