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.

A temperature activated relief plug assembly for mounting in a port on a pressurized structure comprising an assembly housing having a chamber formed therein, means on the housing for mounting the assembly on the pressurized structure in position extending between the interior of the pressurized structure and atmosphere, a first opening in the housing between the chamber and atmosphere and a second opening in the housing between the chamber and the inside of the pressurized structure; means mounted in the second housing opening preventing communication between the chamber and the inside of the pressurized structure, said means including a flanged member having an endless sidewall, an outwardly extending wall formed on one end of said flanged member for movement into position in the second housing opening, and an inwardly extending wall forming a ledge at the opposite end of the flanged member, means closing the second housing opening including a disk member engageable with the inwardly extending wall, and means for removably attaching the disk member to the inwardly extending wall including attachment means which go from a solid to a liquid phase whenever a predetermined temperature occurs in the pressurized structure thereby enabling disengagement of the disk member from the flanged member.
