Abstract

A vacuum arrangement with a vacuum disc valve. A support plate is movably guided along a wall with an opening that is closed or opened by a valve. A seal plate is provided on the support plate which is controlled and actuated through a cylinder chamber. When the support plate is moved, the seal plate is displaced in the direction of the opening and is tightly placed on the borders of said opening by actuation in the cylinder chamber. The resulting sealing forces are absorbed by the movement guides of the support plate.
