Abstract
A membrane valve arrangement () includes a disc-shaped valve membrane () made from an elastic material and a disc () having a central opening (). The valve membrane () is arranged with one side on the disc () and has a circumferential sealing bead () radially outside on the side opposite from the disc. The disc () is arranged, along with the valve membrane (), between a housing upper part () and a housing lower part () of the membrane valve arrangement (). The sealing bead () is clamped between the housing upper part () and the housing lower part (). The sealing action in the region of the sealing bead is largely independent of tolerances because, on at least one of the housing parts in the region of the sealing bead () and/or in the radially outer peripheral region of the disc (), additional sealing arrangements are present.
