ABSTRACT:
A rotating stream sprinkler of the type having a rotatable vaned deflector for stepwise sweeping of relatively small water streams over surrounding terrain to irrigate adjacent vegetation. The sprinkler includes a turbine driven ball drive rotor having at least one drive ball carried by centrifugal force into repetitious impact engagement with one or more raised anvils on the deflector for incrementally displacing the deflector in a succession of small rotational steps. A speed control brake includes a brake pad interposed between a friction surface on the deflector and a nonrotating brake disk to provide a variable friction force to maintain deflector rotation substantially constant within a range of normal water supply pressures and flow rates.
