  • Patent number: 7703706
    Abstract: A variable arc sprinkler nozzle is provided for distribution of water through nearly any adjustable arcuate span. The nozzle includes one or more arcuate slots formed by the helical engagement of spiral surfaces of a deflector and a nozzle body. A user may rotate a portion of the nozzle body to select the arcuate span of the one or more slots. A matched precipitation rate feature is adjustable to proportion the amount of water directed to the deflector depending on the extent of the arcuate span. Further, edge fins on the deflector and nozzle body channel water flow at the two edges of the distribution arc to increase the throw radius and to provide fairly uniform water distribution at the edges of the arc.

  • Patent number: 7621463
    Abstract: A fluid nozzle system (nicknamed the โ€œRAP nozzle systemโ€) is disclosed that combines a pulse flow device with a toroidal vortex generator to create a high momentum, self propelling jet for increasing long-range jet impact forces. In a preferred embodiment, the RAP nozzle system comprises a fluid switch, without any moving mechanical part, which takes continuous flow normally exited through a nozzle and breaks it into discrete patterns of pulsed flow. The unsteady characteristics of the pulsed flow are then used with either single-stage ejectors, multi-stage ejectors or other devices to increase the momentum and/or the lateral size of the individual pulses. These fluid pulses are then used to generate a jet with large scale, stable toroidal vortices which travel long distances, downstream of the ejector(s), and apply large forces at impact.

  • Patent number: 7494073
    Abstract: A fluid discharge apparatus adapted to discharge a cavitating stream of pressurized liquid along with the selective discharge of a secondary material, such as an abrasive, for removing dirt, debris, barnacles, marine growth, and other substances from submerged surfaces is provided. More particularly, the invention contemplates a introducing a pressurized liquid into a cavitation generating chamber to create and discharge a cavitating stream, and a secondary inlet for injecting abrasive material, such as silica, into the chamber to improve cleaning effectiveness. The gas bubbles within the cavitating liquid stream that essentially explode upon impacting debris resulting in tremendous pressure fluxuations provides improved effectiveness in removing debris and aquatic growth from the submerged surface. The combination of a secondary substance, such as an abrasive material, foam, or compressed gas enhances cleaning effectiveness.

  • Patent number: 7478767
    Abstract: An apparatus for regulating fluid flow through a spray nozzle comprising a circular chamber (1) defined by spaced apart end walls, a peripheral side wall (3), a central axis, and a first inlet at or near the peripheral side wall (3) to allow a flow of fluid to enter said chamber (1) tangential to the peripheral side wall (3), and an outlet (4) exiting through one of the end walls. In use a flow of fluid entering through the first inlet has a primary lower layer (16) that follows a first circular flow path which forms a vortex commencing at the peripheral side wall (3) and increases in velocity and pressure towards the outlet and at least one secondary upper layer (17) that substantially follows a second flow path radially inwardly towards the central axis. The primary lower layer (16) and the secondary upper layer (17) interact and support each other over at least a portion of flow between the inlet and outlet (4).

  • Patent number: 7389951
    Abstract: A misting spray nozzle includes a hollow body having an interior wall descending from an upper end to a lower end. The interior wall tapers toward the lower end to form a choke. A channel section provides two fluid paths descending from an upper central aperture. A turbine is sized and shaped to fit closely within the choke and has spiral grooves on its outer surface. The turbine attaches to the body at its upper end and has a cone-shaped opening at its lower end. A conical core is sized and shaped to fit closely within the cone-shaped opening and has grooves spiraling in an opposite direction on its outer surface. The core is attached at its upper end to the turbine. The two sets of spiral grooves define a pair of intersecting fluid control paths that meet at the lower end of the body to create a dense mist.

    Abstract: A pump-dispensing atomizer includes a dispensing pump with a closure to engage with a container. The dispensing pump includes a pressing button with a booster chamber formed inside, a nozzle with one end extending from the pressing button and a probe formed with at least one section. An interior of the nozzle is formed with a guide chamber, and one end of the guide chamber is connected to the booster chamber. The guide chamber has at least one expanding sub-chamber. After the probe is disposed in the guide chamber, a boosting channel is formed between the expanding sub-chamber and the stepped section. Moreover, the pressure accumulator is mounted on the other end of the nozzle, which is formed with a spraying opening communicated to outer environment. As such, the pressure of liquid flowing in the nozzle will be increased effectively so that liquid is sprayed out with a higher pressure to increase the spraying speed of the liquid.
