  • Patent number: 9739388
    Abstract: Devices and methods for extracting a beverage from a container, such as a wine bottle. Beverage can be extracted from a container by inserting a needle through a container closure, such as a cork, delivering pressurized gas into the container via the needle, and dispensing beverage from the container via the needle. A pressure regulator may control a pressure of gas introduced into the container, and a lance used to pierce a pressurized gas cylinder may include a leading face arranged to reliably pierce a cylinder closure. The regulator may include valve features to reduce valve chatter or hammering and provide a more reliable pressure seal.

  • Patent number: 9718319
    Abstract: A pressure and temperature compensated valve assembly includes a flow valve allowing inflation flow from a control port to a tire port and controlling deflation flow from the tire port to the control port. A throttle valve restricts deflation flow between the tire port and the control port when deflating the tire at high flow rates or when tire pressure is high, thus enabling the flow valve to be closed. The throttle valve includes a throttle diaphragm that throttles in response to flow from the tire port and which does not restrict inflation flow from the control port. The valve assembly further includes a temperature responsive member engaging the flow valve, and which deforms in response to a change in temperature in the valve assembly, thus negating temperature effects on the flow valve, allowing the flow valve to close at a consistent force across a range of operating temperatures.

    Abstract: A patient-support apparatus includes an inflatable support structure, a variable output pump, a power supply and a controller. The pump includes a driver that is responsive to variations in the power signal applied to the driver to vary the output from the pump. The pump output is varied depending on the amount of flow needed as determined by a sensor that senses the pressure in the inflatable support structure.

  • Patent number: 8387671
    Abstract: A purge valve for a mounted assembly for a vehicle consisting of a wheel comprising a rim and of a tire, the valve comprising a body associated with the rim and a piston able to move with respect to the body between a closed position and a purge position and the valve being normally closed. The opening of the valve is obtained by the moving of the piston into the space radially external to the rim, the opening being obtained by action of a control force on the piston, exerted from the space radially internal to the rim, and provided by compressed air led from the space radially internal to the rim to the radially interior surface of the piston and the compressed air led from the space radially internal to the rim to the radially interior surface of the piston being at a pressure lower than or equal to that of the mounted assembly.

  • Patent number: 8387650
    Abstract: An auto compression valve, comprising a rear housing with an air release hole; a front housing screwed with the rear housing; a taper piston moveably mounted in the rear housing; a spring mounted in the front housing, wherein one end of the spring is placed in the cavity of the front housing, another end is sleeved on the cylinder end of the taper piton; a lock ring with an air release groove fixed between the rear and front housings. Air release is realized through the air release hole and the air release groove, thus all parts of the valve can be assembled more tightly to prevent coming loose, maintaining the necessary pressure for inflating tires and controlling the air leaking flow in deflation.

  • Patent number: 8297309
    Abstract: An inflatable product has an air pump device and a pressure releasing valve. The air pump device has a housing and a pumping assembly. The housing has two openings as an inlet opening and an outlet opening. The pumping assembly is mounted in the housing and has a motor and a fan. The motor is mounted between the inlet and outlet openings and drives the fan. Consequently, mounting the motor between the first opening and the second opening dissipates the heat of the motor because the air passing by the motor cools the motor. The pressure releasing valve is adjusted by users and releases air while pressure of air in the inflatable body reaches a predetermined pressure level.

    Abstract: A configurable fluid transfer system for inflatable footwear includes a manifold. The manifold is part of an inflation system having an underfoot pump connected to one of the plurality of openings in the heel side of the manifold, an inflatable forefoot bladder connected to two of the plurality of openings in the bottom surface of the manifold and an inflatable heel bladder connected to one of the plurality of openings in the bottom surface of the manifold. fluid flows from the underfoot pump to the inflatable forefoot bladder through a one-way valve and into a first channel in the manifold connected to a forefoot bladder. The fluid inflates the forefoot bladder and exits into a second channel in the manifold. Fluid flows from the inflatable forefoot bladder to the inflatable heel bladder through the second channel and inflates the heel bladder. A pressure regulator including a porous material may be in fluid communication with the fluid transfer system to control the rate of fluid exiting the system.

  • Publication number: 20120090698
    Abstract: A pressure control and feedback system for an adjustable foam support includes a vacuum pump for drawing air from a hermetically sealed foam core to reduce the firmness of the core. A valve opens to permit and closes to block the passage of air into and out of the core. A remotely operated controller generates control signals to selectively start and stop operation of the pump, and selectively open and close the valve, which provides a selected level of pneumatic pressure and corresponding firmness in the core. A pressure sensor detects the pressure and firmness of the core and generates representative feedback signals. An indicator device responsive to the feedback signals indicates the sensed firmness of the core. Software calibrates the system and provides the system with intelligent operation.

  • Publication number: 20120048392
    Abstract: A pressure relief valve device includes a mount adapted to be mounted on an inflatable article, and having an abutment mount defining a valve port, a valve disc disposed outwardly of the abutment mount to be axially movable to open and close the valve port, and having a stem extending through the abutment mount for connecting a biasing member. Once internal air pressure of the article exceeds a preset pressure determined by the biasing member, the stem is forced by an excess pressure of the internal air to lift the valve disc away from the valve port so as to permit escape of the internal air out of the article through the valve port for relieving the overpressure in the article.

  • Publication number: 20110272038
    Abstract: An adapter assembly is taught for attaching a tire pressure monitor onto an inflation valve which incorporates a distal end flange. An adapter is included in the assembly consisting of a collar having a configuration sized to fit over and be internally retained by the valve distal end flange, and an O-ring is positioned on the flange contiguously engaging the collar. A tire pressure monitoring cap is threadably attached to the collar which is disposed above and compresses the O-ring between the cap, collar and valve end flange. The adapter permits the tire pressure monitor to be attached, for use with a tire pressure monitoring system (TPMS) and also could prevent possible minor air leaks. The adapter may be packaged in a kit with appropriate instructions. Alternatively the tire inflation valve could be included with the adapter, forming the adapter assembly, or the monitor could be included in either case, when desired.
