Emergency degassing device

An emergency degassing device, comprising:

• a housing defining an interior and an exterior, the housing including at least one gas passage opening communicating the interior and the exterior, and the housing including at least one air passage communicating the interior and the exterior;
• a gas-tight membrane closing off the gas passage opening;
• a gas-permeable membrane covering the air passage to provide a venting element to allow air to vent through the air passage;
• and
• a cutting element supported from the housing at a distance from the gas-tight membrane, the cutting element configured such that upon a predetermined deformation of the gas-tight membrane the cutting element cuts the gas-tight membrane at least at one point to create a flow connection between the interior and the exterior through the gas passage opening;
• wherein the housing includes a gas guide providing a spatial connection between the at least one gas passage opening, the at least one air passage and an environment surrounding the exterior of the housing, the gas guide including at least one wall element covering the at least one gas passage opening and the at least one air passage.

• wherein the housing includes an annular recessed attachment surface;
• wherein the gas-permeable membrane includes a circumferential connection section;
• and
• wherein the device further includes a annular support including an annular circumferential attachment surface, the circumferential connection section of the gas-permeable membrane being attached to the annular circumferential attachment surface in a gas-tight manner, the annular support further including a radially outwardly extending coupling flange connected to the annular recessed attachment surface of the housing.
