Abstract
A sealing ring made of an elastomer material is fitted on the front side of an essentially rectangular valve plate for sealing a vacuum valve opening. On the rear side, the valve plate has a recess with an undercut boundary wall which forms a sloping surface which, for fastening the valve plate on a carrier, is braced with a sloping surface of the carrier. The valve plate has a lug which protrudes beyond the rear side thereof and has a through-passage bore through which a clamping screw is screwable into a threaded bore of the carrier, for bracing the valve plate sloping surface with the carrier sloping surface. In a side view of the valve plate, seen parallel to the longitudinal sides, the straight-line extension of the longitudinal center axis of the through-passage bore runs past the sloping surface at a distance from the rear side of the valve plate.
