  • Resealable vent valve for a rechargeable battery
    Patent number: 4556612
    Abstract: A pressure relief valve is provided for venting gas from the interior of an electrochemical cell when the pressure of the gas within the cell is excessive. The valve effects sealing or the interior of the cell from the atmosphere when the pressure in the cell is not excessive. Within the relief valve first and second seals are disposed in series in a fluid path and serve not only to enhance the sealing function but also cooperate with resilient means to avoid substantial variations in valve opening pressure if the resilient means are misaligned during assembly of the valve.
