The present invention relates to rotary sprinklers, and is particularly directed to an improvement to the type of rotary sprinkler described in U.S. Pat. No. 4,261,515.
The above Application describes a rotary sprinkler comprising a nozzle having an inlet connectable to a source of pressurized water and formed with an axial bore through which the water exits in the form of an axial jet, a rotor in the path of the axial jet, and means for floatingly mounting the rotor for axial, lateral and rotary movements with respect to the nozzle bore, the underface of the rotor being formed with at least one groove (preferably two) extending from the rotor center to its outer edge for deflecting the jet laterally of the sprinkler and for imparting a rotory motion to the rotor.
