Abstract
A vacuum valve includes a valve housing with a valve opening, a closure member, a valve rod on which the closure member is mounted and which is axially adjustable for adjusting the closure member between open and closed positions, an elastic seal arranged on a front side of the closure member or on the valve seat of the housing, a sealing surface arranged on the other of these, and against which the seal abuts in the closed position, and at least one support part arranged on a rear side of the closure member remote from the valve seat. The abutment between the support surface of the support part and the valve housing is effected in an abutment plane which is inclined in relation to the displacement direction about an axis which is at right angles to both the displacement direction and the longitudinal axis. The support part is pivotable in relation to the closure member about a pivot axis, which is at right angles to both the displacement direction and the longitudinal axis of the valve opening.
