Patent ID: 8800587

Claim:
A thermal pressure relief device (TPRD), comprising: a hollow housing having a first end and a second end allowing a fluid to flow through the housing; a movable member disposed in the housing and movable between an open position and a closed position, at least a portion of the movable member sealing the first end of the housing when the movable member is in the closed position; a retainer fixedly disposed in the housing; and a trigger mechanism disposed between the movable member and the retainer, the trigger mechanism including a non-pyriform shaped body having a temperature sensitive material disposed therein, wherein the temperature sensitive material expands volumetrically with an increase in temperature, and wherein the trigger mechanism permits a movement of the movable member from the closed position to the open position when a predetermined temperature of the temperature sensitive material is attained, wherein the housing is formed from a thermally conductive material to facilitate a transfer of heat to the temperature sensitive material of the trigger mechanism, wherein the movable member includes a plurality of longitudinal bores formed therein to facilitate a fluid flow therethrough when the movable member is in the open position.
