Abstract: A sprinkler including a fixed base defining a water inlet and a nozzle, a rotating assembly arranged for rotation relative to the fixed based about a rotation axis and including a water stream director, receiving a pressurized stream of water from the nozzle and directing it in a generally radially outward direction and a rotation speed governing assembly operatively associated with the rotating assembly and operative to intermittently reduce a speed of rotation of the rotating assembly, so as to thereby increase a radial range of the stream, the rotational speed governing assembly including a rotating enclosure rotating together with the rotating assembly and enclosing a viscous material, a static element and a moving element.
