Abstract
An improved low pressure reverse buckling rupture disk and assembly are provided. The rupture disk comprises a concave-convex reversible member having a thickness and a configuration such that said member reverses when a predetermined fluid pressure is exerted on the convex side thereof and having one or more reinforcing embossments disposed therein. The rupture disk assembly includes the above-described rupture disk and knife blade means for severing the disk upon its reversal.

An improved low pressure reverse buckling rupture disk comprising a concave-convex rupturable member having a thickness and a configuration such that said member reverses when a predetermined fluid pressure is exerted on the convex side thereof and having one or more reinforcing embossments disposed therein.
An improved low pressure reverse buckling rupture disk assembly comprising:
- a reverse buckling rupture disk having one or more reinforcing embossments disposed therein;
- and
- knife blade means positioned adjacent to said rupture disk for severing said rupture disk upon the reverse buckling thereof.
An improved low pressure reverse buckling rupture disk assembly comprising:
- a reverse buckling rupture disk having a concave-convex portion connected to an annular flat flange portion and having one or more reinforcing embossments disposed in the concave-convex portion;
- and
- knife blade means positioned adjacent to said rupture disk for severing said disk upon the reverse buckling thereof.
