 wodurch dieser nach rechts in die in Fig. 2 gezeichnete Lage geschoben wird. Hierbei verbindet er den Kanal 13, damit den Zylinderraum 14 durch die Einschnürung. 18 mit dem Auspuff 19, so dass der   Kolben   also nunmehr unbehindert, nach Vollendung seines Rückganges, von der im Raum 8 befindlichen Druckluft getrieben wird, seinen Vorwärtsgang nach rechts bis zum Schlag ausführen kann. 



   Da der Kanal 15 in der rechten Schieberstellung durch die   Einschnürung 20   mit dem Kanal 7 verbunden ist, findet Einströmung in den Raum   8,   während der Kolben nach rechts geht, auf dem   Wege     (e 6-5-4-15-7 solange statt, bis der Kolben 2 den Kana15 abdeckt. Durch den Kanal 15   
 EMI2.1 
   längert   wird. 



   Wenn der Kolben 2 dann in die in Fig. 2 gezeichnete Stellung kommt, die   Öffnung   5 also die Einströmung bereits abgedeckt hat, legt er das Auspuffloch 21 frei, wodurch die im Raum 8 befindliche Druckluft entweichen kann. Hierdurch wird auch der mit diesem Raum verbundene Raum hinter der grösseren Fläche 17 des Steuerschiebers 9 drucklos, so dass der auf die kleinere Fläche 11 ständig wirkende Druck denselben nach links in die in Fig. 1 gezeichnete Lage bringt. Hierbei ist der andere Zylinderraum wieder mit der Einströmung verbunden, wodurch der Kolben 2 nach links bewegt wird und das Spiel von neuen beginnt.

 whereby it is pushed to the right into the position shown in FIG. Here it connects the channel 13, thus the cylinder space 14 through the constriction. 18 with the exhaust 19, so that the piston is now unhindered, after completion of its decline, driven by the compressed air in space 8, can execute its forward gear to the right until it hits the stroke.



   Since the channel 15 in the right slide position is connected to the channel 7 by the constriction 20, flow into the space 8 takes place while the piston moves to the right on the path (e 6-5-4-15-7 as long as until the piston 2 covers the channel 15. Through the channel 15
 EMI2.1
   is extended.



   When the piston 2 then comes into the position shown in FIG. 2, that is to say the opening 5 has already covered the inflow, it exposes the exhaust hole 21, whereby the compressed air in the space 8 can escape. As a result, the space connected to this space behind the larger surface 17 of the control slide 9 is also depressurized, so that the pressure constantly acting on the smaller surface 11 brings it to the left into the position shown in FIG. Here, the other cylinder space is again connected to the inflow, whereby the piston 2 is moved to the left and the game begins again.

PATENT-ANSPRUCH : Steuerung für Gesteinbohrmaschinen und andere Maschinen mit hin und her gehenden Kolben ohne äussere mechanische Steuerung, dadurch gekennzeichnet, dass ein voller Arbeits- EMI2.2 raum führenden Kanal (7) verbindet, worauf in bekannter Weise die Umsteuerung des Hilfsschiebers eintritt und die Zuführung durch den Hilfskanal (15) fortgesetzt wird, bis der Kolben den Kanal (5) wieder abdeckt, während beim Rückwärtsgange der Hilfskanal (15) durch den Schieberwulst abgedeckt wird und der : Auspuff nur kurze Zeit geöffnet bleibt, um Kompression im hinteren Zylinderraum zu erzielen. PATENT CLAIM: Control for rock drilling machines and other machines with reciprocating pistons without external mechanical control, characterized in that a full working EMI2.2 Space-leading channel (7) connects, whereupon the reversal of the auxiliary slide occurs in a known manner and the supply through the auxiliary channel (15) is continued until the piston covers the channel (5) again, while the auxiliary channel (15) through the reverse gear Slide bead is covered and the: Exhaust only remains open for a short time in order to achieve compression in the rear cylinder chamber.
