Abstract
A pressure relief device which operates between a closed condition wherein a fluid is contained within a vessel and an open condition wherein the fluid is discharged from the vessel by flowing through the pressure relief device. A plug is mounted within a cavity of a plug housing which is secured with respect to the vessel. The plug housing and/or the plug form at least one passageway. In the open condition of the pressure relief device, the passage allows communication between an inlet and an outlet of the plug housing. In the closed condition of the pressure relief device, there is no communication through the passageway and thus the fluid does not flow from the inlet to the outlet of the plug housing. A void, preferably an annular space, is formed between the plug and the plug housing. A fusible alloy, or other suitable eutectic material, is at least partially filled within the void.
