Abstract
A safe pressure relief assembly of the reverse acting rupture disc type guards against very low pressure differentials and includes a thin, bulged sealing disc, a cutting member positioned in spaced relation to the sealing disc and extending a substantial transverse distance thereacross and a sealing disc support member having a stay arrangement projecting into supporting engagement with the concave side of the sealing disc, the stay arrangement having a resistance to collapse sufficient to retain the sealing disc out of contact with the cutting member only up to a predetermined differential pressure.
