 das im Kanal 28 eintretende Druckmittel gegen Entweichen abgesperrt, während das im Kanal 29 zutretende Druckmittel durch den   Kana ! 25 hindurch   nach der Aussenseite des Kolbens 18 strömen kann. Hiedurch wird der Kolben 18 bis an die Grenze seines   Eingangshubes gedrückt   und dabei der Arm 13 am Ring 9 verstellt. Gleichzeitig wird durch diesen Arm der Kolben bis an die Grenze seines   Auagangshubes verschoben,   wobei der Raum vor dem Kolben 17 durch die   Kanäle 24     und 26 mit   der Aussenluft in Verbindung steht. 



   Da in diesem Falle die Kupplung 10 freigegeben ist, so dreht sich trotz der Drehbewegung des Ringes 9 das Futter 8 nicht. Nähert sich der Arm 13 dem Ende seiner Bewegung, so bewegt sein Zapfen 15 das Ventil 21 an die Grenze seines anderen Hubes in die Stellung nach Fig. 5, demzufolge das durch den Kanal 29 strömende Druckmittel abgesperrt und das durch den Kanal 28 strömende Druckmittel unter Vermittiung des Kanales 24 nach der Aussenseite des Kolbens 17 geleitet wird. wodurch sich der Kolben nach einwärts bewegen muss. Dadurch wird

 Nähert sich dann der Kolben 17 der Grenze seines Eingangshubes, so wird der Zapfen 15 am Arm 13 veranlasst, auch das Ventil 21 in seine Ausgangsstellung zurückzubewegen, während w elclen Zurückdrehens der Ring 9 durch die Walzen 10 mit dem Futter 8 gekuppelt und dadurch das Bohrwerkzeug 7 umgesetzt wird. 



   Bei der Stellung der Teile nach Fig. 5 ist der Raum vor dem Kolben 18 durch die   Kanäle 2J   und 27 mit der Aussenluft in Verbindung und die   Kanäle 26, 27   in der Ventil kammer 12 sind während der Hin- und Herbewegung des Ventiles 21 von den beiden Kopfenden desselben ab-   wechselnd überdeckt.

 EMI2.1
 the pressure medium entering the channel 28 is blocked from escaping, while the pressure medium entering the channel 29 through the Kana! 25 can flow through to the outside of the piston 18. As a result, the piston 18 is pushed to the limit of its input stroke and the arm 13 is adjusted on the ring 9. At the same time, the piston is displaced by this arm to the limit of its output stroke, the space in front of the piston 17 being connected to the outside air through the channels 24 and 26.



   Since the coupling 10 is released in this case, the chuck 8 does not rotate despite the rotary movement of the ring 9. When the arm 13 approaches the end of its movement, its pin 15 moves the valve 21 to the limit of its other stroke in the position according to FIG. 5, consequently the pressure medium flowing through the channel 29 is shut off and the pressure medium flowing through the channel 28 under Mediation of the channel 24 to the outside of the piston 17 is passed. causing the piston to move inwards. This will
 EMI2.2
 If the piston 17 then approaches the limit of its input stroke, the pin 15 on the arm 13 is caused to move the valve 21 back into its starting position, while the ring 9 is rotated back by the rollers 10 with the chuck 8 and thereby the drilling tool 7 is implemented.



   In the position of the parts according to FIG. 5, the space in front of the piston 18 through the channels 2J and 27 with the outside air in connection and the channels 26, 27 in the valve chamber 12 are during the reciprocating movement of the valve 21 of the both head ends of the same alternately covered.
