ABSTRACT:
A sprinkler includes a stationary body portion including a fixed nozzle, and a rotatable rotor plate mounted in a hub in vertically spaced relationship to the nozzle. The rotor plate is adapted to receive and redirect a stream emitted from the nozzle. The hub which mounts the rotor plate has a first plurality of teeth formed on an external, annular surface thereof. An annular stream interrupter is loosely held on the hub and in surrounding relationship to the first plurality of teeth. The interrupter also has a plurality of stream interrupting fingers depending from a radially outermost peripheral surface thereof, arranged to be struck by the stream redirected by the rotor plate. The interrupter includes a ring having a second plurality of teeth formed on an interior annular surface thereof adapted for partial and progressive meshing engagement with the first plurality of teeth to thereby cause the interrupter to orbit the hub in a step-by-step, eccentric motion by the action of the stream on the interrupter fingers.
