Abstract
A vacuum lock on a vacuum chamber has a lockable gate opening with a substantially vertical gate and the following characteristics: the gate is a sliding plate displaceable parallel to the opening; the gate is connected via a driving rod on a side oppose the opening and is supported at a distance in the sliding direction; this connection is via a guidance mechanism such that in the presence of a blockage of the closing process, the gate is laterally pressed on a seal encompassing the opening; and a spring element is provided to narrowly compensates the weight of the gate. This ensures that in the event of a operator error or unintentional reaching into the opening during a closing process, injuries cannot occur and a high degree of safety is ensured.
