  • Publication number: 20230307780
    Abstract: 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.

  • Patent number: 10844761
    Abstract: 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.

  • Patent number: 9859575
    Abstract: A humidifier is provided with a housing and a stacked unit inserted into the housing that is provided with water vapor-permeable membranes and frame parts, wherein the frame parts are stacked on each other and the water vapor-permeable membranes are arranged between the frame parts, respectively, so that the water vapor-permeable membranes are stacked on top of each other and are spaced apart from each other. The housing has supports that hold the stacked unit. The supports and the frame parts are connected to each other by a connection that is made of laterally projecting connecting tabs and a receiving groove extending in vertical direction, wherein the connecting tabs engage the receiving groove.
