Abstract
A reverse buckling disc having a central domed region, an outer flange and an integral transitional region interconnecting the flange and the domed central region wherein the included angle of the transitional region is greater than the included angle of the domed region, such that the reversing pressure of the disc is determined by the angle of the transitional region rather than by the height of the dome.
