Abstract (en)
[origin: WO2011138325A1] In a protective housing of the pressure-proof enclosure type, a pressure-relief device (18) which comprises a porous body (23) is provided. The edge of said porous body is provided with a pore seal (31) in order to prevent a flame from penetrating at its edge. The pore seal forms a connection without gaps in conjunction with the surrounding receiving body (19). For example, the porous unprocessed body (23) can be encompassed on the edge region by a soft metal ring and can be pressed, for example, by a predetermined conical contour of a receiving body and a pressure ring such that the deformation produces an embedding without gaps. In addition, the deformation can be maintained in a permanent manner by means of resilient elements in order to compensate for the thermal expansion of the various materials during temperature fluctuations.
