  • Publication number: 20030080213
    Abstract: The invention relates to a method and a device for distributing liquid media, in particular extinguishing fluids. The aim of the invention is to provide a method and a device of the aforementioned type which can be used to produce a fine mist of small droplets and a jet spray of large droplets at separate moments, at approximately the same operating pressure of the extinguishing fluid, depending on the outbreak and the development of the fire, whilst at the same time minimising water consumption, reducing water damage caused during a fire and increasing cost-effectiveness, by creating a modular system which can he universally installed. To achieve this, the intensity of the vortex and the proportion of fine or large droplets in the spray cone is adjusted by regulating the quantity and speed of the flow during the distribution of the extinguishing fluid in at least two sub-streams and by combining said sub-streams with at least one additional sub-stream.

    Abstract: A fluidic nozzle having multiple operating modes comprising a fluidic oscillator circuit having an oscillation chamber having an upstream end and a downstream end and a power nozzle at the upstream end for introducing a jet of a liquid (water) into the oscillation chamber. An outlet throat at the downstream end has a width, which does not allow the oscillation circuit to fill up and start to oscillate without entrained liquid. A pair of control ports are at the upstream end of the oscillation chamber and a pair of feedback passages connect said control ports to downstream ends of said oscillation chamber adjacent said outlet throat. A pair of controllable entrainment holes are provided in the oscillation chamber at the upstream end and a valve opens and closes the entrainment holes, such that when the entrainment holes are open to air, air is entrained and the oscillator does not oscillate.

  • Publication number: 20020185553
    Abstract: A slim, ergonomic spray head includes a shell that defines a smooth tubular shape. A body is disposed in the shell and includes two water passages disposed in spaced-apart relation, forming an opening therebetween. A diverter for selecting between an aerator and a sprayer includes a piston and a trigger actuator that are completely contained within the smooth tubular shape. The engagement of the piston and actuator is located in the opening between the passages. The body further includes an outlet that directs an outflow of water along the longitudinal axis of the body. By matching the tubular shape to the shape of a faucet, the spray head appears to be an extension of the faucet, rather than a conventional bulky pull-out sprayer, providing a more pleasing appearance.

  • Patent number: 6322004
    Abstract: A spa jet comprising a first nozzle, a second nozzle, and an aeration chamber therebetween, are all disposed in a housing. One seal forms a watertight seal between the first nozzle and the housing, and another seal forms a watertight seal between the second nozzle and the housing. A ring is affixed to the second-nozzle downstream end, and a third nozzle is pivotally mounted in the ring. A retainer is mounted to the ring and it frictionally secures the third nozzle in any one of a continuum of angular positions. The ring can be a ball-bearing ring, whereby the third nozzle can freely rotate in the ball-bearing ring under the force of a water stream exiting the third nozzle. A non-circular opening in the third nozzle assists in rotating the third nozzle even when centered in the ring. A barrel, comprising the first and second nozzles and the aeration chamber, has latching tabs formed thereon, and the housing has a retaining profile formed therein for engaging the latching tabs.

  • Patent number: 6254014
    Abstract: The present invention provides an apparatus with a moving nozzle that delivers fluid in a wobbling, rotating or oscillating pattern. The movement of the nozzle is a wobbling motion, preferably combined with some rotational motion. The wobbling motion is generated by disposing a wobble inducing member or wobble turbine in the path of the fluid supply. The water flowing over the wobble turbine causes the turbine to wobble. The wobbling turbine then causes the nozzle to wobble or rotate. The moving nozzle can be used as a motor providing a rotating output shaft or ring.
