If the pre-tensioning body 11 is a spring pre-tensioned in tension, it pre-tensions the shut-off element 20 and thus the shut-off element 8 towards the blocking position. If, on the other hand, the pre-tensioning body 11 is a spring pre-tensioned in compression, it pre-tensions the Shut-off body 20 and thus the shut-off element 8 in the direction of the open position shown in Fig. 13.

Apart from the pre-tensioning body 11, the fourth exemplary embodiment is based on the third exemplary embodiment. The only difference is that here again the pre-tensioning body 11 is provided, which in the manner already described in the second exemplary embodiment can pre-tension the shut-off body 20 and thus the shut-off member 8 in the direction of one of the end positions, i.e. towards the blocking position or the open position.
