<p>Disclosed is a circular or sector sprinkler, a nozzle arrangement of which has a sprinkling range that can be modified in accordance with the angle of rotation. Said sprinkler includes a control cam which annularly surrounds the axis of rotation and which can be transformed into a non-planar shape by means of adjusting means distributed along the periphery. The adjusting means are designed as adjusting levers which can be vertically pivoted, at hinges, about horizontal pivot axes that extend tangentially to the axis of rotation, lie on a plane running perpendicular to the axis of rotation, and vertically support the control cam in discrete positions.</p> |
