  • Patent number: 9625095
    Abstract: A sealed and insulating reservoir contains a pressurized cold fluid in a rigid, sealed enclosure. A fluidtight membrane is positioned to contact the cold fluid contained in the reservoir. An insulating barrier is placed between the fluidtight membrane and the internal surface of the rigid enclosure, with the insulating barrier forming a support surface to support the fluidtight membrane. A pressure balancing device is able to limit the pressure difference between a first sealed volume located inside the fluidtight membrane, and a second sealed volume located outside the fluidtight membrane. The pressure balancing device typically includes a fluid circuit having two chambers sealingly separated by a movable separator. The first chamber is linked to the first sealed volume, and the second chamber is linked to the second sealed volume. The movable separator exerts a loading force in the direction of the second chamber.

  • Patent number: 9416756
    Abstract: A valve element in a valve chamber is movable between an OFF position and an ON position to switch a flow quantity of fluid between a large flow quantity and a small flow quantity. The valve chamber has a fluid passage including an outer passage defined between an inner periphery of the valve chamber and an outer periphery of the valve element. The valve chamber has a throttle shape to decrease in inner diameter gradually from upstream toward downstream to decrease a minimum passage area of the fluid passage in a non-linear form. The valve chamber increases a differential pressure across the valve element in a linear form relative to a stroke of the valve element when the valve element moves from the OFF position toward the ON position.

    Abstract: Diaphragm joint and convolutions, bottom screen diffuser, air stern, cap, and diaphragm restrictor systems for a pressure vessel are disclosed. A convoluted diaphragm divides the vessel into a pair of sealed chambers. The convoluted geometry of the diaphragm minimizes stress on the diaphragm at maximum displacement conditions. An H-ring, with or without being over-molded by the convoluted diaphragm, may be configured to receive end portions of the tank liners. A bottom diffuser, coupled to an inlet of the vessel, diffuses and mixes water flowing into and out of the vessel and drains water out of the vessel. Fiberglass windings surround and lock the tank liners in tension. The cap system includes a valve cap that engages an air stem. An outer cap covers a recess of the vessel and includes a hollow cavity that receives the valve cap. A diaphragm restrictor limits upward movement of the diaphragm within the vessel.

  • Patent number: 8261764
    Abstract: The air charger system provided is configured to provide an air supply to a pressurized water storage system without the use of external power. The system includes a venturi vented to the ambient atmosphere, such that the venturi siphons air from the ambient atmosphere when the venturi reaches a choked flow condition, and the system stores the siphoned air in a charging tank to supply a water storage tank. In various embodiments, the air charger system conserves energy because the use of external power is eliminated. Instead of using a traditional air compressor, the air charger systems converts the potential energy of water in a storage tank to kinetic energy in order to pressurize air in a charging tank. In addition, the air charger system also achieves greater energy conservation with the elimination of an air compressor, such that the system requires less repair and maintenance than a traditional system.

Dispersion liquid is supplied while the pressure of a circulation tank on the delivery side is lower than the atmospheric pressure but higher than the pressure of the space in buffer tanks. The dispersion liquid in the discharge chambers is recovered while the pressure in a circulation tank serving as recovery destination is lower than the atmospheric pressure. Gas dissolution can be reduced because the dispersion liquid does not come into contact with gases at pressures higher than the atmospheric pressure and engulffing gas or deformation of solid microparticles can be avoided because no pump is used.

  • Patent number: 7044404
    Abstract: A fluid delivery device for supplying fluids, particularly automotive fluids supplied to fluid reservoirs. To attain this, a vessel configured to hold a liquid includes a pressurized gas inlet configured to receive gas into the vessel through a passageway in an integral handle upon actuation of a handle-mounted trigger. Liquid is displaced from the vessel by the gas. In an embodiment, the trigger includes a stem having a solid portion and a hollow portion, and actuation of the trigger aligns the hollow portion with the passageway such that gas may flow. Liquid flows through a hose extending from the vessel.

  • Patent number: 6976497
    Abstract: Liquid raising systems raise liquid from a system inlet to a system outlet without any moving parts below the system outlet. One or more closed cells are disposed at elevations between the system inlet and outlet. A liquid conduit leads from the bottom of each cell to the top of the next downstream cell. Gas pressure-differential between two next-adjacent cells causes liquid to flow through the liquid conduit to the next cell. The pressure-differential need be only enough to move the liquid between adjacent cells. The cells are cyclically filled and emptied by sequentially applying the gas at higher and lower pressures to adjacent cells, thus progressively moving liquid toward the system outlet. A cell can have a variety of shapes and sizes, so long as the cell gas inlet is above the liquid inlet, and the liquid outlet is below both the liquid inlet and the gas inlet.

  • Patent number: 6595957
    Abstract: An apparatus for controlling the volume of surgical fluid present in a cavity of the body during surgery includes a fluid pump for pumping surgical fluid to the cavity via a conduit. A dampener is disposed between the pump and the cavity, with the dampener receiving the fluid output of the pump and having a pressure sensitive volumetric capacity, therefor such that variations in output volume of the pump are diminished by the dampener, the output of which is directed to the cavity. The dampener may be in the form of a hollow chamber into which surgical fluid flows trapping a selected quantity of gas thereabove with the gas quantity being determined by a vent valve. A hydrophobic filter or a float valve may be employed as the vent valve.

  • Patent number: 6167756
    Abstract: A float for a liquid level detection apparatus including a tube extendable through liquid in a tank. The float is a buoyant body slidably mounted about the tube and having a diameter passable through an aperture in the tank. The float is preferably formed of two separate bodies joined by spacers positioned to allow the body to pivot from a first position substantially axially in line with the tube for insertion and removal of the float with respect to the tank to a second position substantially perpendicular to the tube in operative floating engagement with the liquid surface in the tank. The spacers, in one embodiment, are in the form of pins arranged in pairs along opposite side edges of the two bodies and spaced apart along the length of the two bodies such that the innermost pins of the two pairs of pins define an aperture for mounting the bodies transversely about the tube in the second, floating position.

  • Patent number: 5485865
    Abstract: An air volume control valve apparatus is provided for use with a water system pressure tank. The apparatus includes an elongated tube that is supported on the tank with a first end exposed to an area exterior of the tank and a second end within the tank. A valve is provided for controlling the volume of air in the tank. The valve includes an elongated, buoyant float member having a first axial end supported for pivoting movement on the tube about a pivot axis extending in a direction transverse to the length of the tube, and a second free end opposite the first end. As the water level rises in the tank beyond a predetermined level, the float member is lifted on the water to an upper pivoted position in which the second end of the tube is closed off, and when the water level drops beneath the predetermined level, the float member pivots away from the upper position and the second end of the tube is uncovered.
