초록

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 ...

청구항

What is claimed is: 1. A method of shutting off fuel flowing through a conduit defining a frangible area therein, the method comprising:defining a chamber about the frangible area having an expansible member forming at least a portion of the chamber;using fluid pressure in the conduit line to expand the expansible member; andusing the expansion of the expansible member to shut off fuel flow through the conduit.
