  • Patent number: 9216427
    Abstract: A system for deflecting and distributing liquid from a liquid source is provided. The system comprises a deflector turbine element incorporated at one end of a cylindrical rotor which encloses at least a portion of the nozzle and is guided coaxially along the nozzle by at least one guide ring. The turbine element fixed to the rotor cylinder further comprises at least one diagonal groove configured to receive and deflect the liquid. The rotor or spindle element is configured to spin relatively freely around the nozzle (hollow shaft) and is allowed to reposition up or down along the nozzle shaft limited by the force of the water jet in one direction and a repelling magnetic force in the opposite direction.

  • Publication number: 20100065656
    Abstract: A sprinkler device comprising a rod having a distribution plate secured thereto, the rod located relative to a nozzle adopted to emit a liquid onto the water distribution plate to thereby create a force on the rod in one direction; a support component including at least two retaining rings through which the rod passes; and a pair of magnets, one of which is fixed to the rod and the other of which is located in proximity to the one magnet, wherein poles of the magnets are arranged to create a repulsion force tending to move the rod in a second direction opposite the first direction.
