Abstract
A vacuum slide gate valve with a drive unit that is formed in such a way that a closure plate, by displacement of at least one valve rod along a longitudinal axis, is displaceable from an open position into an intermediate position, and, by displacement of said valve rod along a transverse axis running at right angles to the longitudinal axis, is displaceable from the intermediate position into a closing position. The valve rod is rigidly connected to a sliding part, which is guided between a first position and a second position parallel to the longitudinal axis, and between the second position and a third position parallel to the transverse axis. A displacement member is mechanically coupled to the sliding part via an inclined connection to displace the sliding part from the first position into the second position and from the second position into the third position.
