Abstract
A thermally responsive pressure relief system is provided for a receptacle such a pressure vessel. A passage communicates the interior of the vessel with the exterior thereof. A closure member is positioned in the passage. A fusible bonding material of a selected melting point fixes the closure member in the passage. The closure member includes an integral rupturable section that ruptures at a selected pressure differential between the interior and the exterior of the vessel. The closure member may be mounted in a body member which, in turn, is mounted in an opening in the pressure vessel. The body member may be mounted on a valve which has the passage from the interior of the vessel communicating therethrough.
