    摘要： A rigid mount orbitor sprinkler assembly (10) incorporates a deflector plate configuration (22) that is configured for both spinning/rotating motion as well as orbital or wobbling motion around the center of a spool assembly (32). The sprinkler includes a spider ingress opening (572) cooperable with a spider barrier (570) that in combination permit inevitable spider ingress while preventing spider access or contact with certain moving parts of the sprinkler.

    摘要： A rotational speed control device (10) includes a housing (16) containing a viscous fluid and a shaft (14) disposed in the housing (16) and rotatable relative to the housing (16). A rotor (12) may be movable axially on the shaft (14) depending on the rotating speed of the shaft (14). The rotor (12) is biased in a low torque direction. A braking torque between the rotor (12) and the housing (16) and/or between the rotor (12) and a drive control ring (1102) is varied according to an axial position of the rotor (12) on the shaft (14). The device (10) may incorporate bypass channels (1116) to control a circulating pressure of the viscous fluid.

    摘要： A rotary sprinkler includes: a shaft (12) having a cam (36), the cam (36) having a plurality of radially outwardly projecting cam lobes (44); a rotatable water distribution plate (16) adapted to be impinged upon by a stream emitted from a nozzle causing at least the water distribution plate to rotate; a hesitator assembly including a stationary housing having a sealed chamber at least partially filled with a viscous fluid, with at least the cam (36) and the cam lobes (44) located within the chamber; a rotor ring (38) located within the chamber in substantially surrounding relationship to the cam (36), the rotor ring (38) loosely located within the chamber for rotation and translation, the rotor ring (38) provided with at least two hesitator lobes (48,48') projecting radially inwardly and movable laterally into and out of a path of rotation of the cam lobes (44), and a first plurality of radially outwardly projecting teeth (52) selectively engageable with a second greater plurality of teeth (56) provided on an inner wall of the housing; and wherein rotation of water distribution plate is slowed during intervals when one of the cam lobes (44) engages and pushes past a respective one of the hesitator lobes (48,48'), the cam lobe (44) exerting both rotation and translation forces on the rotor ring (38), with one of the first plurality of teeth on the rotor engaging one of the second plurality of teeth on the housing wall.

    摘要： A system for deflecting and distributing liquid from a liquid source is provided. The system comprises a deflector turbine element (28) incorporated at one end of a cylindrical rotor (26) which encloses at least a portion of the nozzle (12) and is guided coaxially along the nozzle by at least one guide ring (22). 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 (18,20) in the opposite direction.

    摘要： A rotary sprinkler includes a sprinkler body including a nozzle, a water-deflection plate supported for rotational movement relative to the sprinkler body, the water-deflection plate having one or more grooves configured to cause the water-deflection plate to rotate when impinged upon by a stream emitted from the nozzle; a first brake arranged to slow rotation of the water-deflection plate at all times; and a second brake arranged to further slow rotation of the water-deflection plate as a function of water pressure exerted on the water-deflection plate.
