ABSTRACT:
A safety cut-off device, comprises a valve for controlling fluid flow. The valve has a body with a passageway therethrough and inlet and outlet communicating with the passageway. The valve includes a closure member disposed within the passageway, the closure member having an open position for permitting fluid flow through the body and a closed position for shutting off the fluid flow. A stop has an operative position engaging the closure member in the open position and an inoperative position when the closure member is in the closed position. The stop is biased in the operative position. A vibration sensitive member is secured to the valve body, the vibration sensitive member being adapted to move the stop to the inoperative position in response to vibrations in the environment, whereby the closure member is permitted to move to the closed position.
