Abstract
A sprinkler unit having a continuously rotating nozzle includes a stream interruptor comprising a pin mounted on a carriage pivotally mounted on the nozzle and a cam surrounding the nozzle that has a series of cam surfaces for intermittently caming the carriage assembly and the interrupting pin into the stream to periodically interrupt the stream as the nozzle rotates about its axis to cause a more even distribution of water over the surface area surrounding the sprinkler unit.
