  • Fluid flow release regulating device
    Patent number: 5244309
    Abstract: A self supporting rubbery flow blocking device of substantial thickness is mounted in a fluid passageway to automatically regulate flow. Due to its variable elastic stiffness, increases in pressure will cause the device to begin to flex away from the pressure, beginning at its free end. Further increases in pressure will cause the location of the flex to move towards the secured edge of the invention, unblocking larger areas of flow. Decreases in pressure will allow the invention to increase its blocked area until it regains its fully blocking state.
