ABSTRACT:
An energy efficient water sprinkler has a housing with primary and secondary water chambers each with a turning wheel for translating the force of impacting water to rotational motion of a central shaft journal. Water is forced through a central channel in the rotating shaft and discharged from the housing. A portion of the discharged water is directed to deflection fins on the outer surface of the housing to further impart rotational or energy to the rotating shaft.
