Abstract:

The patent relates to a differential pressure relief valve wherein a diaphragm piercing device is actuated by differential pressure through a bellows. The device is self-contained and is installed in the bulkhead of a sealed container. As the pressure inside the container becomes greater than the pressure outside, the bellows compress to a fixed compressed height of the bellows, and a spring loaded hollow plunger is released and is driven through a diaphragm on the bellows end, thus venting the container to the outside atmosphere.
