ABSTRACT:
A sprinkler head includes: a body assembly including an adapter, a nozzle, a spindle and a first magnet, the spindle supporting a spool having a pair of axially-spaced radially-oriented spool flanges; a nutating cage loosely mounted on the spindle, between the radial flanges of the spool, the nutating cage supporting a second magnet in close proximity to the first magnet; a water distribution plate carried by the nutating cage and adapted to be impinged upon by a stream emitted from the nozzle. The first and second magnets are arranged with like poles facing each other such that the second magnet is repulsed from the first magnet, but when the stream impinges on the water distribution plate, the second magnet is moved towards the first magnet, with magnetic repulsion force increasing and causing the nutating cage and the water distribution plate to tilt off axis.
