  • Patent number: 5942351
    Abstract: A moisture-proof housing is disclosed intended for containing a battery. The housing includes two walls or plates which are kept in place by a sealing band located therebetween which defines interior of the housing. Portions of the walls, namely wall or plate protrusions, extend beyond the sealing band. One of the plates has a hole located exterior to the housing during normal conditions. The sealing band includes a movable part which slides between the two plates. When the interior housing pressure exceed the exterior pressure, the movable part slides outward to include the hole within the housing interior. This provides a safety valve and vents out the excessive interior pressure. A stop device is provided to avoid excessive displacement of the movable band, such as displacement beyond the plate protrusions.

  • Patent number: 5258243
    Abstract: A pressure relief valve, according to the invention, is mounted on a vent orifice providing a gas passageway from an interior plenum of a battery or a cell thereof to the ambient atmosphere. The valve fits on the vent orifice and opens to release gas at a high threshold battery gas pressure and reseals the vent orifice when the internal pressure of the battery drops to a low threshold.

  • Patent number: 5217823
    Abstract: A vent cap for use in a recombinant battery which includes a hollow barrel configured for gas-tight insertion into a vent hole in a battery cover. A retaining flange is formed at the closed end of the barrel, and a one-way relief valve formed on the barrel near its closed end. A layer of a polyalkylene explosion attenuating material surrounds the outside of the barrel below the flange and surrounding the relief valve. The polyalkylene material provides effective attenuation of explosions that occur in the vicinity of the relief valve. The invention further provides a vent cap assembly wherein the foregoing vent cap is mounted on a plastic vent cover of an otherwise conventional battery container.

  • Patent number: 5215835
    Abstract: A metal oxide-hydrogen battery having an outer safety shell. The battery to be used in a confined area such as in an aircraft or manned spacecraft, and includes a pressure vessel that contains at least one cell module. Hydrogen gas under pressure is confined within the pressure vessel and is impregnated in the cell modules. An outer shell, preferably formed of molded plastic, is disposed around the pressure vessel and a vent conduit connects the space between the vessel and the shell with the exterior. Any hydrogen that accidentally leaks from the vessel is captured in the space and vented to the exterior.

  • Patent number: 4965144
    Abstract: A resealable pressure vent for a container such as a battery container having a wall containing an aperture connecting the interior of the container with the atmosphere comprising a cover member in the form of a metal plate which is spot welded at its center to the center of the wall of the container. The aperture is located in the wall away from the center thereof and an elastic O-ring is interposed between the metal plate and container wall such that the O-ring seals the aperture from the exterior of the container. In the event of excess pressure within the container, the O-ring is displaced by the said excess pressure to vent the container and the O-ring returns to its original sealing position when the excess pressure is relieved.

  • Patent number: 4927719
    Abstract: A dry cell which is so arranged that, with a bottom plate being disposed at the lower portion of a raw cell sealed at its opening by a sealing member, an insulative seal packing is applied onto the peripheral portion of the bottom plate, while the raw cell and the peripheral portion of the bottom plate are surrounded by a metal jacket welded by laser at its butted opposite ends. At the peripheral portion of the bottom plate, a gas discharge mechanism is formed which is arranged to be normally closed by the seal packing, and to be released from the closing by the seal packing due to deformation of the bottom plate upon increase of internal pressure of the dry cell for discharging the gas within the dry cell outside, and thus, a safe dry cell free from a danger of rupture maybe provided.

  • Patent number: 4780378
    Abstract: A relief/check valve for venting an electric storage battery comprising essentially an annular sealing member having an elastomeric skirt engaging the sloping exterior surface of a valve seat. The skirt flares outwardly from the seat in direct proportion to the pressure in the battery such as to prevent excessive build up of pressure in the battery when the gassing rate is high. The skirt quickly returns to a sealing condition when the pressure within the battery drops below the opening pressure of the valve.

  • Patent number: 4131722
    Abstract: A resealable vented battery container having a sealed casing with a plastic closure having a vent port and a recess on the outside of the closure surrounding the vent port. A metal grommet in the port has a sleeve portion extending through the port with a washer-like surface at the inner end of the sleeve and in contact with the inner surface of the closure around the vent port. A metal rivet, having a head portion at the outer side of the closure and in the closure recess and a stem portion extending through, but spaced from, the wall of the grommet sleeve portion, is upset at its inner end into contact with the grommet washer-like surface. A resilient, O-ring is gripped between the inner side of the rivet head and the bottom wall of the closure recess and expands and stretches when the pressure in the container is increased, venting the excess container pressure from the container.
