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. |
