   Bei der Lage des Kugelgesperres (Fig. 2) wird das Futter   8   durch den Ring 9 nicht gedreht. 



  Der Kolben 18 stisst weiterhin mit seiner   Innenfläche   gegen den Zapfen 15 am Ventil 21 an und steuert es um (Fig. 5).

   tnngesetzt wird.   



   Gleitet der Kolben 17 nach innen zurück, so bewegt er unter Antreffen an den Zapfen 15 das Vcntil 21 in seine Anfangsstellung zurück. 



   In der Stellung der Teile (Fig. 5) gelangt der Raum vor dem Kolben 18 durch die Kanäle 25   und 27   mit der Aussenluft in Verbindung. 



   Aus vorstehendem geht hervor, dass die   Kanäle   26 und 27 in der Kammer 12 während des   Hin- und Herverschiebens   ihres Ventiles 21 abwechselnd von den voneinander abgewandten   Enden des letzteren überdeckt werden.

 EMI2.1
 



   In the position of the ball locking mechanism (FIG. 2), the chuck 8 is not rotated by the ring 9.



  The piston 18 continues to abut with its inner surface against the pin 15 on the valve 21 and controls it (FIG. 5).

   is connected.



   If the piston 17 slides back inwards, it moves the valve 21 back into its initial position when it hits the pin 15.



   In the position of the parts (FIG. 5), the space in front of the piston 18 comes into contact with the outside air through the channels 25 and 27.



   It can be seen from the above that the channels 26 and 27 in the chamber 12 are alternately covered by the ends of the latter facing away from one another while their valve 21 is being pushed back and forth.

 by means of pistons moved by the pressure medium, which rotate a ring that oscillates back and forth around the drill axis and is connected to a ball lock, characterized in that a piston-
