ABSTRACT:
A device for dissipating the accidental over-pressure of a fluid contained in an enclosure provided with a sealing membrane intended to be deformed and broken by the over-pressure comprises a mobile piston applied against the membrane subjected to the action of a spring by means of an overcenter spring mechanism having a threshold of balance which, when exceeded, causes the sudden releasing of the piston and the breaking of the membrane, the threshold being reached by the movement of the piston under the action of the deforming of the membrane. The invention applies to the protection of the enclosures under fluid pressure.
