Abstract
A lock chamber for conveying a workpiece from one medium (U.sub.0) into another medium (U.sub.7) which comprises a lever (11) acting as a transport system and pivotably mounted in the chamber on one side. With lock gates (5a, 5b) moves aside the lever (11) can swing out by a required degree into the respective media (U.sub.7, U.sub.0). With the design of the transport system as unilaterally mounted levers (11), the volume of the lock chamber is largely independent of the trajectory of the lever and the volume can be minimized (FIG. 1).
