ABSTRACT:
A water distribution plate and diffuser plate assembly for distributing a stream emitted from a sprinkler nozzle includes: a nonrotatable shaft having one end attached to a sprinkler component and an opposite end supporting first and second plates in axially spaced relationship for rotation about the shaft independent of one another. The first plate is axially adjacent the nozzle and formed with plural water distribution grooves shaped and arranged to divide a single primary stream emitted from the nozzle into a plurality of secondary streams. The second plate is downstream of the first plate and formed with plural diffuser elements arranged to be struck by at least some of the secondary streams exiting the first plate. The speed of rotation of one or both plates is slowed by viscous damping.
