Abstract
A vacuum valve having a valve body, a closure member, a valve rod which supports the closure member, a guide piece by which the valve rod is movably guided parallel to a longitudinal displacement direction, a longitudinal travel drive by which the valve rod is displaceable with respect to the guide piece parallel to the longitudinal displacement direction, a transverse travel drive, and a slide part which is movable by the transverse travel drive, is guided by a primary linear guide to be movable with respect to the valve body, and is guided by a secondary linear guide to be movable with respect to the guide piece. The primary and secondary linear guides each run at an angle of less than 45° with respect to the longitudinal displacement direction, and the primary linear guides form an angle of more than 3° and less than 45° with the secondary linear guides.
