ABSTRACT:
Apparatus which can be installed over an opening on a container and can provide relief of excessive pressure conditions and excessive vacuum conditions in the container and provide rapid temperature actuated pressure relief for the container in the event of fire or other potentially dangerous heat related conditions, the apparatus including an aperture therethrough communicating with the container opening and a member releasable maintained in the aperture with a substance which melts at a predetermined temperature to enable pressure in the container acting against the releasable member to separate and even blow the releasable member from the apparatus and escape from the container through the aperture, the preferred construction including a self-actuating and self-modulating combined pressure and vacuum relief valve assembly which provides accurate pressure relief for the container at a predetermined over pressure condition and high inflow rates of air for vacuum relief at a predetermined excessive vacuum or negative pressure condition, the combined relief valve assembly being mounted on the releasable member.
