ABSTRACT:
A temperature actuated relief plug assembly for mounting in a port in a pressurized structure to provide pressure relief when the temperature of the gases in the pressurized structure exceeds some predetermined temperature, the assembly including a metallic body having a portion for mounting in the port in the pressurized structure and a portion extending externally therefrom, the metallic body having a chamber therein and an opening communicating the chamber with the interior of the pressurized structure, and a temperature actuated structure closing the opening in the body and exposed to the temperature of the gases in the pressurized structure, the temperature actuated structure including a first member with a passage therethrough mounted in the opening and a second member soldered to the first member in position closing the passage therethrough by a solder material that has a predetermined melt temperature which will cause the second member to separate from the first member when the temperature of the gases in the pressurized structure equal or exceed the predetermined temperature.
