Abstract
A vacuum valve including a valve body with first and second valve openings, first and second closure elements attached to a valve rod, a longitudinally adjustable transmission piece attached to the valve rod that is adjustable from an open position into an intermediate position, and in a transverse adjustment direction from the intermediate position into a first closing position, and counter thereto into a second closing position. The transmission piece is connected to the valve body via a longitudinal stroke linear guide and a transverse stroke linear guide having a transverse stroke guide part which extends parallel to an oblique adjustment direction and a transverse stroke carriage displaceably guided thereon. To adjust the transmission piece from the intermediate position into the first or second closing position, the transverse stroke carriage is linearly displaceable in or counter to the oblique adjustment direction from a central position into a first or second press-on position.
