  • Patent number: 9618130
    Abstract: A multifunctional valve features a pumping function and a vacuuming function. The valve can be implemented in any closed container having a removable lid or a bag having a resealable zipper or any other similar sealable feature. The valve also features a tethered plug to additionally provide sealing. The valve incorporates a spacer or washer when used in thin walls to provide support. When the valve is used with a bag, the spacer or washer incorporates footing so that the valve does not collapse on its own when the valve is used in conjunction with a vacuum pump or a gas pump.

  • Patent number: 6929021
    Abstract: An inflation/deflation valve for filling a dunnage bag with air includes a sleeve for insertion into an opening in a wall of the bag, a cap for covering the sleeve and threaded onto the sleeve and an inflation head for engaging the cap. A valve is mounted in the cap having a valve seat, a valve member moveable generally axially of the sleeve and a spring biasing the movement of the valve member in the axial direction toward the valve seat. The cap has mounting lugs on the base adjacent the bag arranged for engagement with co-operating slots of the inflation head in a bayonet fitting where the slots are shaped so that the head is cammed by the lugs in the slots to cause depression of an abutment surface of the valve member against the spring bias to open the valve. The removal of the cap allows rapid deflation of the bag for testing or reuse.

  • Patent number: 6755208
    Abstract: A self-sealing valve for controlling the volume of fluid within an inflatable device. The valve includes a housing having a fluid conduit, a valve seat and a valve assembly that selectively seals the fluid conduit to provide a self-seal. The valve assembly includes a support member and a mounting device that holds a portion of a flexible diaphragm in a closed position, and that facilitates movement of at least part of the periphery of the diaphragm away from the valve seat to an open position and towards the valve seat to the closed position. The support member may be manually moved to any of the multiple open positions, either to enable fluid release or to enhance fluid injection. With the injection of fluid, the diaphragm assumes an open position, allowing fluid influx.

  • Publication number: 20040040596
    Abstract: A valve used for an inflatable article includes a valve body and a male connector. The valve body has a rear hollow portion, a female connector attached to the rear hollow portion, and a spring-loaded valve core movable therein. The male connector has a first tubular end and a second tubular end, and the second tubular end is dimensioned to be snugly plugged in the female connector to move the spring-loaded valve core backward. Furthermore, the female connector of the valve body defines a pair of L-shaped slots, while the male connector is formed with a pair of bayonet fittings adapted to be held in the L-shaped slots after the second tubular end is plugged, thereby allowing the male connector to be fastened to the female connector and hence to the valve body in a quick-detachable manner.

  • Patent number: 6508264
    Abstract: A self-sealing valve is used to fill, empty, and control the volume of fluid within an inflatable device. The valve includes a housing having a fluid inlet, a valve seat and a valve assembly that selectively covers the fluid inlet to provide a self-seal. The valve assembly includes a support member that suspends a flexible diaphragm in a closed position within the valve housing while allowing movement of at least part of the periphery of the diaphragm away from the valve seat to an open position and back towards the valve seat to a closed position. The support member may be manually moved to any of the multiple open positions, either to enable fluid release or to enhance fluid injection. With the injection of fluid, the diaphragm assumes an open position, allowing fluid influx. A fluid pressure created within the device assists in maintaining the diaphragm in the closed position.

  • Patent number: 6460560
    Abstract: A low profile inflation valve intended to be installed with an article to inflated with air, water or other fluid. The valve of the invention comprises a valve body which is sealed, such as by an adhesive, heat-sealing or RF sealing, to a corresponding opening in the article to be inflated. The body comprises a generally circular cylindrical configuration with internal threads for receiving a cap. The cap correspondingly comprises a circular cylindrical configuration having exterior threads for threaded engagement into the valve body. A flapper is affixed to the underside of the cap and functions as a one-way valve to prevent fluid from within the article from escaping therefrom when the cap is partially threaded within the body and yet which allows inflation of the article. Moreover, full tightening of the cap within the body sealingly entraps the flapper between the cap in a lower portion of the body so as to create an airtight seal and prevent further inflation (or deflation) of the article.

    Abstract: A closure for a container incorporating an air valve to facilitate inflation of a bladder within the container. The closure includes a plug for sealing an opening with the container lid. The plug has a central aperture within which is seated a valve adapter. Extending through the aperture and engaging the valve adapter is a valve stem fluidly connected to an inflatable bladder. The valve adapter maintains the valve stem above the closure for connection to an air supply for inflation of the bladder. A cap snap-fits over the adapter and valve stem to protect the valve from contaminants and damage. The bladder is inflated after the container has been filled.

  • Patent number: 6296010
    Abstract: This invention is an automatic shut-off valve and gauge for tires during inflation. Configured as a double stem valve joined either on the outside or inside the rim of the tire. One stem serves as an air valve for inflating tires with a metal or plastic line attached to it extending into the second stem, which is a valve that regulates the air pressure in the tire. Air supplied during inflation of the tire causes a linkage to move and open a vent to the atmosphere which was otherwise closed. A spring loaded valve is designed to open when the air pressure in the tire exceeds the correct operating pressure and to allow excess air to escape to the atmosphere. A retracting and extending indicia is provided on the top of a spring loaded valve to indicate when the tire is properly inflated to a preset pressure.

  • Patent number: 6279600
    Abstract: A theft resistant valve cap including a liner adapted for threaded engagement with a standard pneumatic tire stem valve, a sleeve rotatably mounted with the liner to shroud it and an interlocking feature to selectively prevent axial displacement between the liner and the sleeve. The interlocking feature includes a screw threaded into an aperture in the sleeve, or other coupling device, and an annular channel on the liner, positioned to receive the screw. The annular channel has an upper surface, a lower surface and an inner surface disposed between the upper and lower surfaces. The screw is moved so that it extends into the channel resting proximate to the upper surface, but clear of both said lower and inner surfaces. The screw can be removed after the valve cap has been installed. In this fashion, the liner and the sleeve are in a fixed axial position with respect to each other; however, the rotatability of the sleeve with respect to the liner is maintained, preventing removal of the liner from the stem.
