ABSTRACT:
A sprinkler for irrigating an area having a shape with an irrigating liquid includes a base; an inlet disposed on the base for receiving the irrigating liquid from a source; and a nozzle having a central axis, the nozzle being rotatably coupled to the base about the central axis and operatively coupled with the inlet to receive the irrigating liquid, the nozzle being adapted to spray the irrigating liquid out onto the area. The sprinkler also includes an adjustable valve operatively coupled between the inlet and the nozzle for controlling a flow rate of the irrigating liquid through the nozzle; a plate being coupled to and rotatable with the nozzle and having a plate axis which is co-axial with the central axis, the plate including a cam surface having a contour which corresponds with the shape of the area; and a lever element having a cam engaging element which engages the cam surface, the lever element being operatively coupled to the valve such that the contour of the cam surface causes the valve to control the flow rate of the irrigating liquid.
