  • Patent number: 10683942
    Abstract: A vacuum valve including a valve housing with seat surrounding a first opening with a sealing surface is disclosed. A valve disk having a first disk section and a second disk section tightly mounted inside an outer boundary of the first disk that is movable parallel to an opening axis. A drive is connected to the first disk section. The first disk section includes a first bearing surface configured to contact the sealing surface in the closed position. The outer boundary has a radially inwardly oriented inner surface. The second disk section has a radially outwardly oriented outer surface configured to contact the inner surface sealing a second contact area. At least for determined radial angles about a center of the valve disk, a first radial distance from the center to the first bearing surface is shorter than a second radial distance from the center to the second contact area.
