ABSTRACT:
A sprinkler assembly having a discharge nozzle for discharging water at a substantially constant volume and velocity driven rotatably about a vertical axis by a water turbine and gear drive for rotating said nozzle at varying rotational speeds in each cycle of rotation for varying the quantity of water discharged along the radial land areas extending from the axis of rotation as the length of the radial land area varies when irrigating a non-circular land area. A movable diffuser is mounted on the nozzle and is drivingly connected with the gear drive by a cam arrangement to vary the radial length and pattern of discharge of water corresponding to the rotational speed of the nozzle with the greatest radial length of discharge of water occurring when the nozzle is travelling at its slowest rotational speed. The diffuser includes a blade movable laterally of the nozzle to split the stream of water as it is being discharged and a radiused groove formed in the upper surface of the water passageway in the nozzle opposed relation to the tip of the blade with the blade causing back pressure with part of the water being caused to flow around the periphery of the groove and to be discharged downwardly across the water passageway for diffusing the stream of water and varying the pattern of water discharged from the nozzle. Ridge-type baffles are formed on opposite walls of the passageway downstream of the blade to breakup the stream of water into a finer spray for improving uniformity of distribution.
