Abstract
A rupturable pressure relief assembly of small unitary construction is provided comprised of a hollow housing which includes an annular supporting shoulder within the interior thereof, a circular rupture disk positioned within the housing on the annular supporting shoulder and an annular supporting member positioned within the housing which coacts with the annular supporting shoulder to clamp the rupture disk therebetween. A protruding annulet means is provided for contacting and biting into the rupture disk whereby it will not be moved by fluid pressure and a deformable annular spring means is positioned on the opposite side of the annular supporting member from the rupture disk whereby when the outlet end of the housing is folded over the deformable annular spring means, the rupture disk is rigidly clamped between the housing and the supporting member with the protruding annulet means biting into the rupture disk.
