  • Patent number: 8651331
    Abstract: A refrigeration appliance with a water dispenser includes a refrigerated cabinet having a dispenser area, a cabinet water inlet in the refrigerated cabinet connectable to a premises water line, and a cold water storage tank in the refrigerated cabinet. The tank has a tank body, an inlet for admitting water into the tank body supplied via the cabinet water inlet, and an outlet for providing water via a dispensing conduit to a dispenser in the dispenser area. The inlet includes a venturi portion for creating a reduced pressure within the tank body via flow of water into the cold water storage tank. The reduced pressure is in communication with the dispensing conduit via the outlet so that, after dispensing operation is completed, water remaining in the dispensing conduit is drawn toward the tank body. The tank body may include an evacuation chamber open to atmosphere, and a float valve may be provided.

  • Patent number: 8484949
    Abstract: A method is provided for monitoring of the functionality of an After Treatment Injector (ATI) for injection of a fluid in an engine exhaust gas system upstream of an exhaust gas treatment unit. The monitoring is performed by using a pressure sensor which detects the pressure of the fluid delivered to the ATI for a specific condition or injection cycle. The pressure sensor is located downstream of a flow regulator and upstream of the ATI in a conduit for supplying of a substance from a container to the ATI. An ECU is programmed to perform a predetermined sequence of opening and closing commands for the flow regulator and the ATI, furthermore perform a frequency analysis of the measured pressure value in order to monitor the functionality of the flow regulator, the ATI and the pressure sensor. The method is adapted to be used in connection with an On Board Diagnosis (OBD) system.

    Abstract: Bottled water dispensers are disclosed that include a water bottle receptacle. The water bottle receptacle includes a first and second floating baffle (with a hole disposed in the center portion of the second floating baffle). A raised ring having a triangular cross-sectional shape is located at the bottom portion of the receptacle, which makes contact with the second floating baffle, when the second floating baffle is buoyantly forced upwards into the raised ring to close an aperture through which water is transferred from the water bottle into a cold tank of the water dispenser (during hot water sterilization procedures, when the water level in a cold tank of the dispenser exceeds a threshold level). The second floating baffle is effective to prevent the undesirable heating of water contained within the water bottle during such hot water sterilization procedures.

  • Patent number: 7775397
    Abstract: An automatic valve assembly for a water cooler having a reservoir of the type that has its upper end generally sealed to the atmosphere by a water bottle adapter that receives and supports an inverted water bottle. The valve assembly includes a ventilation passageway providing for air to enter the reservoir, and an actuator arm hingedly mounted within the interior of the water cooler. The actuator arm is operable to move between an open and a closed position in response to changing water levels within the reservoir. When in its open position the actuator arm allows the unrestricted passage of air into the reservoir through the ventilation passageway. When in its closed position the actuator arm restricts the flow of air and fluids through the ventilation passageway.

    Abstract: A liquid delivery system includes a first reservoir having a first outlet through which liquid is delivered. A first delivery outlet is located at the lower portion of the first reservoir and a vent is included at its upper portion. A second reservoir located above the first reservoir and has a second outlet located in its lower portion. A first delivery conduit connects the second outlet to the first reservoir and a second delivery conduit connects the upper portion of the first reservoir with the upper portion of the interior of the second reservoir. A vent valve controls communication through the second delivery conduit. A level sensor senses the level of liquid in the first reservoir and causes the vent valve to open when the liquid falls below a first predetermined level and to close the vent valve when on the level rises above a second (higher) predetermined level.

  • Patent number: 6293429
    Abstract: A variable-rate, digitally controlled fluid metering device having an electronically controlled 3-way valve, a fluid reservoir, a float valve, a check valve and a pressure relief valve that accurately delivers low flow volumes. The flow rate of the device is the product of reservoir volume and pulse rate when the cycle is long enough to fill and empty the reservoir and is a linear combination of cycle time when the cycle is short enough that the reservoir does not fill or empty completely. This device allows the use of large orifice emitters for delivering low flow rates of fluids, which allows the use of lower quality fluids and/or reduces filtration steps and clogging of emitters.

    Abstract: A hand-powered apparatus and method for measuring and dispensing a predetermined volume of liquid. A predetermined volume of liquid is selected using a control knob on the apparatus and a valve is moved to a fill position. The handle on an attached hand pump is then moved alternately up and down causing fluid to be drawn into a measuring vessel. Further upward movement of the handle is prevented upon the fluid level in the vessel reaching the selected volume. Thereupon, the valve is moved to a dispense position whereby continued pumping of the handle is again possible. The handle is alternately pumped up and down causing the fluid to exit the vessel.
