ABSTRACT:
An emergency shutoff valve includes a fluid conduit having a frangible area defined therein, a valve member operatively coupled to said conduit upstream of the frangible area, an expansible chamber having the frangible area defined therein, a movable member defining at least a portion of the expansible chamber, and a linkage operatively coupled to the movable member and the valve member for shutting the valve upon movement of the movable member in response to leakage of fluid through the frangible area. A method of shutting off fuel includes defining an expansible chamber about a frangible area in the conduit, moving a member defining a portion of the expansible chamber in response to leaking fuel, and shutting off a fuel valve in response to moving the movable member.
