Abstract
An improved pressure relieving rupture disk assembly is provided which includes a rupture disk having at least one perforation therein. The perforation at least partially defines a blow-out part in the rupture disk which opens and relieves pressure therethrough when the perforation is sealed and a pressure differential of predetermined magnitude is exerted on the rupture disk. A sealing member is positioned over the perforation in the rupture disk for sealing the perforation when a pressure differential is exerted on the rupture disk.
