Vacuum support and rupture disk assembly

摘要

Vacuum support and rupture disk assembly in which the vacuum support member does not restrict flow through the rupture disk includes a rupture disk having opposite faces defining a plane and a blow-out portion of selected planar dimension; a vacuum support member positionable adjacent a face of the rupture disk and being smaller in planar dimension than the blow-out portion; and a retainer for holding the vacuum support member adjacent the face of the rupture disk and restraining motion of the vacuum support member in all directions except through the rupture disk in such a manner than the entire vacuum support will pass through the blow-out portion if the rupture disk ruptures.
