ABSTRACT:
A rotary sprinkler includes a rotably-mounted sprinkler head, an oscillating arm for impacting the sprinkler head to impart a rotary motion thereto, a spring urging the oscillating arm in one direction, and a reaction member carried by the oscillating arm and having an inlet alignable with the discharge nozzle for receiving the water jet, and an outlet laterally of the inlet for imparting a rotary motion to the oscillating arm in the opposite direction by reaction. The reaction member includes a cylindrical tube bent to define a single helical loop which produces a helical path of travel of the water from its inlet to its outlet extending laterally of the discharge nozzle.
