Abstract
A vacuum valve comprises a valve housing with a valve opening having a longitudinal axis and a valve seat, a valve plate which is displaceable in a straight line in a displacement direction between an open position in which it releases the valve opening and a closed position in which its contacts the valve seat of the valve housing and closes and seals the valve opening, this valve plate being arranged on at least one valve rod which is displaceable axial to the displacement of the valve plate, a flexible sealing ring which is arranged at a front side of the valve plate or at the valve seat of the valve housing, a sealing surface which is arranged at the valve seat of the valve housing or at the front side of the valve plate and which is contacted by the sealing ring in the closed position of the valve plate, wherein the sealing surface and the sealing ring are arranged in parallel planes which are inclined relative to the displacement direction of the valve plate around an axis extending at right angles to the displacement direction and at right angles to the longitudinal axis of the valve opening, and at least one sliding-spacing part which is arranged at the front side of the va…
