Abstract
A sprinkler comprises a turbine rotor (64) and a nozzle means (20) driving the latter, the water jets emerging from the nozzle means (20) as fanned jets so that the water impinges the surface area to be irrigated at a relatively small distance away from the sprinkler also under high pressure. The nozzle means (20) is mounted rotatably to enable differing sectors or sectors differing in size to be irrigated.
