Valving Means For Each Flow Path Patents (Class 239/444)
  • Patent number: 5862992
    Abstract: The invented spray valve DEFINES two orifices that generate respective spray patterns. Preferably, the spray patterns are each conical in shape and coaxially configured so that the inside spray pattern is enveloped by the outside spray pattern. The spray valve includes two bias units that urge respective orifices to close, in a direction contrary to pressure exerted by a pressurized fluid supplied to the spray valve, that urges the orifices to open. The bias units are independently adjustable to control the amount by which each orifice is urged to close so that the proportional variation of the orifice opening size to a given variation in the fluid flow rate through the orifice, or equivalently, the fluid pressure differential across each orifice, maintains the continuity of the spray patterns over a broad range of fluid flow rates.

  • Patent number: 5853130
    Abstract: The present disclosure concerns a fluid dispersion system such as for use in a personal shower. Groups of nozzles on a single showerhead are separately activated and regulated by corresponding valves. Each valve is controlled from a remote panel to provide an appropriate flow of water. A position detection system determines the relative position of a body with respect to the showerhead. The remote panel receives data from the position detection system and adjusts the valves to ensure the user remains in a desired flow of water.

  • Patent number: 5842645
    Abstract: The device is used to generate foam and is installed between a conventional shower head and the corresponding water pipe. The device features a foam generator that uses air, water and a foaming liquid to generate foam inside a chamber located in the body of the device. A method for generating foam is also disclosed. In the device, the chamber is located under the container that provides the foaming liquid and is provided with a jet that receives deviated water and atomizes the water therein. Air is drawn inside the chamber. Foam is generated as the air, water and foaming liquid are mixed inside the chamber. The foam then flows out of the device through a spout. Operation of the device is achieved through the use of a rotative manual selector, by which the user selects various modes, including a soaping mode where only foam is generated. The device can allow a water economy of up to 75% of the water that could have been used otherwise and thus prevents natural resources from being wasted.

  • Patent number: 4011720
    Abstract: A gas generator or rocket motor is provided in which discrete and accurate time vs. flow output relationships or profiles are established by the rotation of a rotor located between the exit and its combustion chamber to various positions to select one of a plurality of primary nozzles or orifices of accurately calibrated predetermined flow characteristics through which pressurized gases from the combustion chamber are directed by passages in the rotor. The gases then flow out of the device through an exit comprising nozzles in the case of a rocket motor.

  • Patent number: 3971512
    Abstract: A valve unit of a spraying apparatus employs two passageways each provided with an independent manually operated valve and leading respectively to a spray nozzle and a jet nozzle. By providing an interconnecting hole between the inlets of the two passageways and forming the passageways in different bore sizes, different proportions of liquids supplied to the two inlets may be selected as determined by which valve is operated. The unit is very useful for the washing and subsequent spraying of cows' udders with a bacteriacide.

  • Patent number: 3958756
    Abstract: A spray nozzle is of a kind including a housing that has a fluid inlet and first and second groups of spray discharge outlets. First and second flow paths are defined in the housing from the inlet to the first and second groups of outlets. Pulsation means in the first flow path cyclically interrupts the flow of fluid from the inlet to the first group of outlets so as to cause a pulsating spray to be discharged therefrom. The second flow path bypasses the pulsation means to cause a continuous non-pulsating spray to be discharged from the second group of outlets. Included are control means for adjustably dividing flow from the inlet between the first and second flow paths.
