ABSTRACT:
A reversible turbine driven sprinkler unit includes a sprinkler head incorporating a nozzle that is continuously driven by a reversible turbine which continuously oscillates the head between selectable reversing stops for covering a selected part of a circle. A water turbine which is driven by the water supply to the nozzle includes a reversible stator for alternating the direction of rotation of the turbine which is drivingly connected through a gear train to the sprinkler head. A reversing mechanism includes a shifting shaft extending axially from the turbine stator through the turbine, the drive train and the sprinkler head terminating in a cylindrical cavity formed in the top of the sprinkler head in which it is positioned, in an adjustable position, reversing stops for alternately engaging a reversing arm mounted on the shifting shaft for shifting the stator of the turbine to its selected alternate positions. A flow interrupter is intermittently driven in one direction by the oscillation of the sprinkler head to change its position in front of the nozzle for intermittently interrupting the flow of water from the nozzle.
