der Druckwirkung unterhalb des Kolbens e wird die Spindel a, bei senkrechter Anordnung infolge der eigenen Schwere von Spindel, Ventilen usw., wieder in ihre untere Anfangs- ! age zurückkehren, und da nunmehr die Umleitung h durch den Ventilkörper b geschlossen ist, können die gereinigten Gase nur durch die Öffnungen 9 entweichen und von hier aus in die Reingashauptleitung Übertreten.
Während bei der Konstruktion nach Fig. 1 lediglich beabsichtigt ist, gegebenenfalls durch Verdrehen des Handrades n den Reinigungsaustrittskanal 9 vollständig absperren zu können, ist bei Fig. 2 die Anordnung so getroffen, dass durch Niederschrauben des ausserhalb dos Absperrgehäuses mit einem Handrad ta versehenen Ventilkörpers d die Öffnungen 9 und die Umleitung h gleichzeitig absperrbar sind.

to adapt to the respective operating conditions, but also to shut off the lines completely at the same time using the switching valves themselves, so that separate shut-off devices, as were necessary in the previous flap design, are not required.
FIGS. 1 and 2 show two exemplary embodiments of the new device. In both figures it is assumed that the valve spindle a and thus the

the pressure effect below the piston e, the spindle a, in a vertical arrangement due to the inherent weight of the spindle, valves, etc., returns to its lower initial! age return, and since the bypass h is now closed by the valve body b, the cleaned gases can only escape through the openings 9 and pass from here into the main clean line.
While the construction of Fig. 1 is only intended to be able to completely shut off the cleaning outlet channel 9 by turning the handwheel n, the arrangement in Fig. 2 is such that by screwing down the valve body d provided outside dos shut-off housing with a handwheel ta the openings 9 and the bypass h can be shut off at the same time.
