Abstract

Official abstract text for this publication.

A thermal pressure relief device (TPRD) is shown and includes a housing having a first end with a first aperture and a second end having a second aperture. The first and second apertures are configured to allow a fluid to flow through the housing. The TPRD includes a trigger member, such as a ball, disposed within the housing. The ball is seated laterally within a retainer. The retainer includes a rim forming a seat for supporting the ball within the housing. The movement of the ball from the first closed position laterally seated within the retainer to the second open position descended within the retainer is caused by an expansion of the rim of the retainer. The rim of the retainer is formed substantially of a temperature sensitive material adapted to expand volumetrically with an increase in temperature. The temperature sensitive material can expand linearly or non-linearly.

First claim

Opening claim text (preview).

What is claimed is: 1. A thermal pressure relief device (TPRD) comprising: a housing defining a fluid flow passage having a first end and a second end configured to allow a fluid to flow therethrough; a retainer disposed in the housing, the retainer having at least a portion formed of a temperature sensitive material configured to expand volumetrically with an increase in temperature, the retainer including a rim having a diameter less than a diameter of the fluid flow passage,…
