Abstract

In a circular sprinkler, as a result of an intermediate gear, the turbine wheel runs muck faster than the jet splitter operating upstream thereof in the flow direction and also constructed as a turbine rotor, so that the sprinkler starts substantially independently of the water flow and an adjusting device can be provided with which it is possible at any time to manually adjust the sector to be watered. A slot-like bottom with an extension of the guide faces connected thereto is used for further increasing efficiency.
