 bleibender Dampfspannung ermöglicht, wogegen bei wechselnder Dampfspannung eine selbsttätige Einstellung der Dampffüllung, also Regelung, durch Verbindung der   Reglerdüae     q   mit dem Dampfregler f bewirkt werden kann. 



   Am Ende der   Abwärtsbewegung   des Kolbens b gelangt der über dem Kolben f noch befindliche Dampf durch den Kanal s und die Umführungsnut t in die Abdampfleitung h, worauf sich der Kolben f entgegen der Richtung des Pfeiles   x   soweit bewegt, bis der Kanal s verdeckt und gleichzeitig die Abdampfleitung u durch den Umführungskanal   l   der Steuerkolbenstange   f1   mit dem Kanal w verbunden wird. Nunmehr kann der im Raum   M ; befindliche   Dampf durch die 
 EMI2.1 
 wieder zurückbewegt, wobei eine Regelung der Bewegung mit Hilfe der durch die Reglerdüse q einströmenden Luft erfolgt. Nachdem die Rückwärtsbewegung des Kolbens b vollendet ist, wiederholt sich derselbe Vorgang von neuem. 



   Der Kolben f kann sowohl seitlich ausserhalb des Kolbens   b, als auch   über dessen Kolbenstange angebracht sowie mit dieser verbunden werden. 



     Die Ausführungsform   nach Fig. 2 unterscheidet sich von der ersten dadurch, dass hier die Spannungsveränderung des elastischen Mittels nicht durch den Kolben b selbst erfolgt, sondern durch den mit ihm in Verbindung stehenden Kolben   o,   welcher aber das in dem Raum   n   eingeschlossene elastische Mittel nicht verdichtet, sondern verdünnt, wobei auf die andere Kolbenseite im Raum p der   Atmosphärendruck   wirkt. Bei der Bewegung des   Kolbens o   wird die Luft im Raum p durch die Reglerdüse q gepresst. 



   An Stelle des zu verdichtenden bzw. zu verdünnenden Mittels kann auch eine Druckbzw. Zugfeder oder dgl. vorgesehen sein. 



   Die im Raum p durch die negative Reglerdüse q bewirkte feinere Regelung der Umdrehungzahl mittels Veränderung der Menge bzw. Spannung des einen elastischen Mittels kann auch in der Weise geschehen, dass dieses auf den Steuerkolben wirkt.

 permanent steam tension enables, whereas with changing steam tension an automatic adjustment of the steam filling, i.e. regulation, can be effected by connecting the regulator nozzle q with the steam regulator f.



   At the end of the downward movement of the piston b, the steam still above the piston f passes through the channel s and the bypass groove t into the exhaust steam line h, whereupon the piston f moves against the direction of the arrow x until the channel s is covered and at the same time the exhaust line u is connected to the channel w through the bypass channel l of the control piston rod f1. Now the one in space M; located steam through the
 EMI2.1
 moved back again, the movement being regulated with the aid of the air flowing in through the regulator nozzle q. After the backward movement of the piston b is completed, the same process is repeated again.



   The piston f can be attached to the side outside of the piston b as well as above its piston rod and connected to it.



     The embodiment according to FIG. 2 differs from the first in that here the change in tension of the elastic means is not effected by the piston b itself, but by the piston o which is connected to it, but which is not the elastic means enclosed in the space n compressed, but thinned, with atmospheric pressure acting on the other side of the piston in space p. When the piston o moves, the air in space p is pressed through the regulator nozzle q.



   Instead of the agent to be compressed or diluted, a pressure or Tension spring or the like. Be provided.



   The finer regulation of the number of revolutions brought about in space p by the negative regulator nozzle q by means of changing the quantity or tension of the one elastic means can also take place in such a way that this acts on the control piston.
