ABSTRACT:
A stream rotor sprinkler having a rotatable nozzle assembly for discharging a stream of fluid, and a rotatable plurality of deflectors mounted to the sprinkler surrounding the nozzle assembly. A water-driven motor impeller is activated by fluid flow through the sprinkler and rotates an attached rotor. The nozzle assembly is integrally attached to the rotor and is rotated thereby. The nozzle assembly includes an annular skirt at its lower end; the deflectors also have an integrally attached annular skirt which is in horizontal concentric relationship with the nozzle assembly skirt. A transmission is mounted to the sprinkler so as to be positioned between the deflector skirt and the nozzle assembly skirt. The transmission is driven by the rotation of the nozzle assembly skirt and in turn rotates the deflector skirt. The nozzle assembly rotates at an angular velocity different than the angular velocity of the deflectors so that the deflectors are not in the same position when the nozzle returns to a given position so that the circumferential coverage of fluid is substantially uniform.
