  • Publication number: 20040124266
    Abstract: An irrigation sprinkler with two viscous brakes. The viscous brakes work in conjunction with each other to maintain a low RPM and also to rotate a water stream diffuser. The water stream is first directed toward a deflector that offsets the stream and angles it toward the area to be watered. The offset stream applies a torsional force on the deflector causing it to rotate. The stream is then interrupted intermittently by the diffuser that is rotating at a different RPM. The end result is a sprinkler that rotates slowly and breaks up the stream of water intermittently to create an even pattern of water on the area being sprinkled without using mechanical parts, such as ratchets or gearing. This is desirable for smooth operation and less chance of the operation being interrupted from contamination by dirt, insects, debris, etc. Also, a more random diffusion of the water is obtained.

  • Publication number: 20020130199
    Abstract: An atomizer for a liquid delivered to an internal combustion engine uses a nozzle positioned such that a substantial portion of the liquid which exits the nozzle will come in contact with the moveable member of an engine induction tract one-way valve. This one-way valve is preferably a reed valve, the moveable member being a reed. The reed or other moveable member has a rapid movement in response to engine operation. When the liquid comes in contact with the rapidly moving reed or other moveable member, it is broken into a mist of relatively fine droplet size. This invention is ideally suited when the liquid is a lubricating oil being delivered to an engine wherein there is minimal fuel in its induction tract or crankcase to thin and spread the lubricating oil to its necessary locations in the engine. It is also useful when the liquid is a fuel, breaking the fuel into smaller droplet size which is more suitable for combustion.

The air pressure tank has valves that control the flow of air under pressure to the hoppers, when needed.

  • Patent number: 5372307
    Abstract: A sprinkler includes a stationary body portion including a fixed nozzle, and a rotatable rotor plate mounted in a hub in vertically spaced relationship to the nozzle. The rotor plate is adapted to receive and redirect a stream emitted from the nozzle. The hub which mounts the rotor plate has a first plurality of teeth formed on an external, annular surface thereof. An annular stream interrupter is loosely held on the hub and in surrounding relationship to the first plurality of teeth. The interrupter also has a plurality of stream interrupting fingers depending from a radially outermost peripheral surface thereof, arranged to be struck by the stream redirected by the rotor plate.

  • Patent number: 5121463
    Abstract: A hot air pulse generator, particularly for use as a hair dryer, includes a housing enclosing an electric heater and air blower for generating a continuous flow of heated air through a passageway leading to a nozzle. A gently curved baffle arranged across the passageway upstream of the nozzle cuts off 50-75% of the cross section of the passageway and converges the heated air as a high speed air stream toward one side of the passageway. A butterfly valve freely rotatable through on a spindle disposed at an acute angle is located between the baffle and nozzle in the path of the air stream and is continuously rotated by the air flow to effect an intermittent pulsed air output flow through the nozzle.

  • Patent number: 5022588
    Abstract: A water toy has a cylindrical deflector mounted on top of an upright hollow pipe that is rotatable about a vertical axis. Pressurized water introduced into the pipe is ejected from a nozzle fluidly interconnected with the pipe wupwardly onto the deflector along a plane which is offset from the deflector axis. The stream of water from the nozzle causes the deflector to rotate which in turn causes water to be thrown off of the periphery of the deflector into an umbrella pattern. If the nozzle has a concentrated spray pattern the umbrella spray is thin and covers a relatively large diameter, and if the nozzle has a fan-shaped spray pattern the umbrella spray is thicker and covers a relatively smaller diameter.

  • Patent number: 4735361
    Abstract: A fluid dispersing apparatus suitable for use as a sprinkler in water irrigation applications whereby a jet of fluid is reflected from one or more rigid surfaces to preserve fluid particle speed. The reflecting surfaces are shaped to provide a variable but adjustable range of sector coverage in the spray pattern while maintaining range of fluid dispersal coverage. Through substitution of system components, a broad range of fluid dispersing requirements can be met with the same basic substructure. In the absence of fluid jet pressure, the principal jet reflecting assembly settles into a compact, low profile configuration.

  • Patent number: 4570857
    Abstract: A flow regulator comprises a sleeve fixed within a body member and formed with an opening serving as a metering passageway, a second sleeve displaceable with respect to the fixed sleeve so as to vary the effective size of the metering passageway, a spring biasing the displaceable sleeve in the direction to enlarge the met metering passageway, and a flow sensor element carried by the displaceable sleeve and impinged by the flowing fluid so as to displace the second sleeve in the direction of restricting the metering passageway. Also described is a spray nozzle including the above flow regulator, and a deflector floatingly mounted so as to be impinged by the jet issuing from the spray nozzle.

  • Patent number: 4392617
    Abstract: An elongated member is provided in the discharge orifice of a spray head nozzle so that the fluid being sprayed is discharged as a hollow stream resulting inter alia in a better and more complete atomization of the fluid in coaction with a low pressure propellant.

  • Patent number: 4356974
    Abstract: A spraying device is described comprising a nozzle formed with an outlet orifice through which the fluid issues in the form of a jet, and a cup-shaped member having a thin wall defining an open end of slightly larger diameter than the outlet orifice. The cup-shaped member is floatingly mounted for lateral and axial movement with respect to the nozzle orifice such that the jet issuing therefrom always impinges the cup-shaped member within its open end. The device further includes limiting means limiting the floating movement of the cup-shaped member.

  • Patent number: 4026470
    Abstract: A shower flow modulator for providing a massaging effect on the skin of a shower user is adapted to fit within the stem of a shower nozzle for modulating the flow of water leaving the nozzle. The shower flow modulator includes a hydrodynamically-shaped member which is attracted into and then repulsed from a stream of water passing through the modulator thereby varying the direction of travel and intensity of the stream to provide the massaging action.
