Abstract
A sprinkler including a sprinkler head incorporating a nozzle; a spool fixed to the sprinkler head in proximity to the nozzle; a cage assembly loosely mounted on the spool, the assembly including a distribution plate at a first end of the assembly downstream of the nozzle and a first magnet at a second opposite end of the assembly upstream of the spool; a mounting element fixed to the assembly between the first and second ends, an inner edge of the mounting element loosely confined between upper and lower flanges of the spool; and a second magnet fixed to the sprinkler head, axially between the spool and the first magnet.

A sprinkler comprising:
- a sprinkler head incorporating a nozzle;
- a spool fixed to said sprinkler head in proximity to said nozzle;
- a cage assembly loosely mounted on said spool, said cage assembly including a distribution plate at a first end of said assembly downstream of said nozzle and a first magnet at a second opposite end of said assembly upstream of said spool;
- a mounting element fixed to said assembly between said first and second ends, an inner edge of said mounting element loosely confined between upper and lower flanges of said spool;
- and
- a second magnet fixed to said sprinkler head, axially between said spool and said first magnet.
A sprinkler comprising:
- a sprinkler head having a center axis incorporating a nozzle, said sprinkler head and nozzle adapted to emit a stream in a downward direction;
- a spool fixed to said sprinkler head in proximity to said nozzle;
- a nutating cage assembly loosely mounted on said spool, said notating cage assembly including a distribution plate located at a first end of said notating cage assembly downstream of said nozzle and formed with one or more grooves adapted to receive the stream emitted from said nozzle, and an upper cage ring at a second opposite end of said nutating cage assembly, upstream of said nozzle and said spool;
- a mounting ring fixed to said nutating cage assembly between said first and second ends, said mounting ring loosely confined between upper and lower flanges of said spool;
- wherein said upper cage ring and said distribution plate are connected to said mounting ring by a plurality of struts.
