Abstract
A pressure relief mechanism seated within a wall of a pressure vessel features a novel flexible seal. The vessel pressure acts against both a spring and an internal valve pressure created by the flexible seal. The pressure relief mechanism can be designed to release over a wide range of critical vessel pressures due to the combination of the resistive spring force and the resistive internal pressure.
