  • Patent number: 7850094
    Abstract: A rotary sprinkler is provided that includes a housing having a riser assembly and a rotatable nozzle turret on an upper end of the riser assembly. The sprinkler includes an arc setting assembly that enables part-circle operation of the turret and a selector assembly that permits selection of either part-circle or full-circle operation of the nozzle turret where the components of the selector assembly are generally separate from the components of the arc setting assembly.
    Type: Grant

  • Patent number: 7677474
    Abstract: A sprinkler is disclosed for improved flow characteristics. The sprinkler has a sprinkler head rotatably supported for distributing water and defining a flow channel for directing water flow therethrough with reduced head loss. The flow channel has a smoothly tapered portion for receiving water and channeling the water towards an outlet in communication with a first nozzle for distributing the water. The flow channel with reduced head loss produces a greater throw distance at a lower trajectory with a lower flow rate and pressure. The flow channel may be formed within a flow channel member positioned within the sprinkler head. The flow channel member may cooperate with the sprinkler head to define a cavity allowing water to pass through the cavity from the flow channel for emission from a plurality of other nozzles.

  • Patent number: 6920899
    Abstract: A fluid control valve for controlling the delivery of water includes a control lever that is movable in two directions by rotation of the lever about two independent axes. The fluid control valve includes a valve body assembly with flow passageways and a housing assembly attached to the valve body assembly to define an interior space. A flow control mechanism positioned in the interior space is constructed to enable movement of the lever about a first axis for translating rotational movement into sliding motion of an upper disk against a lower disk to adjust the water temperature. Rotation of the lever in a second direction translates rotational movement into sliding motion of the upper disk in a second direction to control the water flow rate. A drag spring positioned as part of the control mechanism changes the frictional force or feel between the two directions of lever movement.
