Patent attributes
A sprinkler nozzle includes a nozzle plate having at least one orifice formed therein. A stream deflector is rotatably mounted adjacent the nozzle plate and has a plurality of flutes formed therein that face the nozzle plate. Each flute has an inner portion that can momentarily align with water flowing through the orifice in the nozzle plate during rotation of the stream deflector relative to the nozzle plate. Water flowing through the orifice will be channeled in a generally radial direction by the flute to form a stream of water that is ejected from the stream deflector. The flutes have a plurality of different tangential trajectories relative to the orifice in the nozzle plate so that in combination the streams of water successively ejected from the stream deflector establish a predetermined shape of coverage.
