Zusammenfassung:	A traveling irrigation sprinkler has a water-powered radial inflow turbine for driving a winch that pulls the sprinkler along a path of travel. Water is supplied to a sprinkler gun either directly from an inlet conduit, or indirectly by passing it through the turbine. A diverter valve proportions the direct and indirect flows and provides a first means of controlling the travel speed of the sprinkler. A shiftable transmission drivingly interconnects the turbine and the winch and provides a second means of controlling travel speed. The turbine includes a vaned runner and a scroll which circumferentially surrounds the runner to deliver water at a substantially uniform velocity to the periphery of the runner.
