ABSTRACT:
An improved sprinkler of the type adapted to rotate and create a redefined horizontal spray pattern around it. A rotating turbine drives a cylindrical nozzle assembly having a plurality of nozzle openings therein. The nozzle openings deliver streams of water of variable length and volume. A pattern defining disk is used to continuously and proportionately expose the nozzle openings to the source of pressurized water according to a preset function of the instantaneous rotational position of the nozzle opening as the cylindrical member turns to create the spray pattern. The nozzle openings supply a relatively constant volume of water to all portions of the pattern.
