More Information
Summary:A degassing unit for a housing includes a membrane, and a base body connectable in a fluid-tight manner to an edge of a housing opening of the housing and including an exterior side, an interior side, and a gas passage opening that is closed by the membrane. The membrane is fluid-tightly connected to the base body at an edge surrounding the gas passage opening. The membrane includes weakened areas in which mechanical properties of the membrane are weakened by any one or any combination of a local melting of a material using a laser, scribing and embossing. The membrane further includes a central area interposed between the weakened areas, the central area remaining unweakened. A burst pressure at which the membrane releases the gas passage opening is reduced at least in the weakened areas compared to the central area.
