Abstract:
A vacuum valve including a valve opening, a valve seat surrounding the valve opening, and a valve plate. During closing starting from the open position, the valve plate is moved over a main section of the closing path in a main closing direction parallel to the valve plate and the plane of the sealing surface, and then over a final section running at an angle to the sealing surface plane for guiding the valve plate onto the valve seat. A guide element on the wall that guides the valve plate over the end section of the closing path interacts with a guide element on the valve plate. The valve plate is guided over the final section of the closing path by guide surfaces that are angled relative to the sealing surface, and at least one guide surface is arranged on a guide element of the valve plate or the wall.
