 diesen Kanal f und die Kanäle   9   und   h   strömt Druckluft nun zwischen beide Ventilkörper b und b'. 



  Der Luftdruck mit dem   Federdruck   zusammen sind stärker als der auf dem Ventil lastende Frischdruck und das Ventil b'wird geschlossen, bevor der Kolben den Auspuff überläuft. Sobald der Kolben den Auspuff c öffnet, entweicht auch die zwischen beiden Ventilkörpern befindliche Druckluft, so dass zur Umsteuerung des Ventils b'nur der Federdruck zu überwinden ist. Durch die vor dem Kolben a entstehende Verdichtung wird das Ventil b' geöffnet ; es strömt dann Druckluft auf die vordere Fläche des Kolbens und treibt diesen zurück. Sobald auf dem Rückwärtsgange der Kanal f überlaufen wird, strömt Druckluft durch die Kanäle f', g und h zwischen die   \'entile bund b'1   wodurch das Ventil b'geschlossen wird, bevor auch hier wieder der Kolben a den Auspuff c'überlaufen hat. 



   PATENT-ANSPRÜCHE :
1. Steuerung für durch Druckluft oder dgl. betriebene Maschinen und Werkzeuge, dadurch gekennzeichnet, dass die in einem gemeinsamen, die   Druckmittelzuführungskan le   verbindenden Raum angeordneten   Ventilkörper   zylindrische Form von durchwegs gleichem Durchmesser der Dichtungsfläche besitzen und zur Erzielung des erforderlichen   Schliessdruckes   gegeneinander gefedert sind.

 this channel f and the channels 9 and h, compressed air now flows between the two valve bodies b and b '.



  The air pressure together with the spring pressure are stronger than the fresh pressure on the valve and the valve b 'is closed before the piston overflows the exhaust. As soon as the piston opens the exhaust c, the compressed air located between the two valve bodies also escapes, so that only the spring pressure has to be overcome to reverse the valve b '. The compression occurring in front of the piston a opens the valve b '; compressed air then flows onto the front surface of the piston and drives it back. As soon as the channel f is overflowed on the reverse gear, compressed air flows through the channels f ', g and h between the \' entile bund b'1, whereby the valve b 'is closed before the piston a again overflows the exhaust c' Has.



   PATENT CLAIMS:
1. Control for machines and tools operated by compressed air or the like, characterized in that the valve bodies arranged in a common space connecting the Druckmittelzuführungskan le have a cylindrical shape of consistently the same diameter of the sealing surface and are spring-loaded against each other to achieve the required closing pressure.

Claims (1)

zur Unterstützung der Federwirkung beim Schliessen der Ventile auch noch frisches Druckmittel aus dem Zylinder zwischen die beiden Ventilkörper geleitet wird. to support the spring action when the valves are closed, fresh pressure medium is also passed from the cylinder between the two valve bodies.
