ABSTRACT:
The apparatus comprises a disk shaped shut-off flap located in the passage of a main body. The shut-off flap is mounted such to a rocking shaft that the flap can be lifted off its seat during one phase of movement of the rocking shaft and may be rotated into an open position during a further phase of movement of the rocking shaft. The operating means comprises a linear drive in the shape of a control rod including a control groove. A follower and driving means engages the control groove and the shut-off flap. Accordingly the shut-off flap is guided for above lift off and rotating movements. This linear drive allows an impeccable sealing between the inner space of the shut-off apparatus and the environment.
