| 主权项 | 1. A rotary sprinkler comprising a housing, a rotatable irrigation head fitted with a rotary dampening mechanism and associated with a first magnet assembly, said dampening mechanism being configured for resisting movement of said first magnet assembly; a second magnet assembly associated with the housing; said first magnet assembly and said second magnet assembly are arranged with like poles facing each other so as to generate a repulsion force therebetween, wherein, at least during operation of the sprinkler, said first magnet assembly and said second magnet assembly are in a state of static magnetic equilibrium. | ||
