Publication number: 20230307780Abstract: 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.Type: ApplicationFiled: May 25, 2023Publication date: September 28, 2023Inventors: Thomas TSCHECH, Alrun SPENNEMANN, Juergen KOSICKI, Thomas SCHLEIDEN

Patent number: 10844761Abstract: A unit (10) for the regulation or control of a fluid pressure, having at least one housing section (13, 14) and a switching film (22) connected to the at least one housing section (13, 14) for switching at pressure differentials relative to an ambient pressure acting on the switching film (22), and for the regulation, release or blocking of a flow of the fluid between an inlet (28) and a discharge (30) for the fluid. The switching film (22) is made out of a polymer material having fluorine and carbon. In this arrangement, a hole cross-section (40) of the at least one housing section (13, 14) is closed off by the switching film (22). A method of forming a fluid-tight connection is also disclosed.Type: GrantFiled: October 31, 2017Date of Patent: November 24, 2020Assignee: Mann+Hummel GmbHInventors: Lukas Bock, Volker Kuemmerling, Thomas Jessberger, Heinz Fuchs, Thomas Schleiden, Juergen Kosicki, Thomas Tschech, Herbert Jainek
