  Drehkolbenmaschine. 



   Um bei Drehkolbenmaschinen mit exzentrisch im Zylinder gelagerter Kolbentrommel und radial in dieser verschiebbaren Schieberkolben einerseits eine hinreichende Dichtung zwischen den Stirnenden der Kolbentrommel und den Zylinderdeckeln und anderseits einen möglichst. reibungslosen Gang zu sichern, hat man bereits in die Zylinderdeckel gehärtete Laufring eingesetzt, auf denen gleichartige, an den Stirnenden der Kolbentrommel befindliche, harte Ringe laufen. Ferner hat man die Keilverbindung zwischen der Kolbentrommel und der in axialer   Richtung   dem Zylinder gegenüber unverrückbaren Welle so ausgeführt, dass die Kolbentrommel der Welle gegenüber in den erforderlichen geringen Grenzen verschiebbar ist. 



   Die genannten Mittel haben nicht immer ein einseitiges Anlaufen der   Kolbentrornme] an   einer Zylinderwand und damit Anfressungen dieser Teile verhindern können. 



   Gegenstand der Erfindung ist nun eine solche Maschine, bei der das Anlaufen der Kolbentrommel an der Zylinderwand dadurch verhütet ist, dass zwischen die Enden der   Kolbentrommel   und die den Anlaufdruck aufnehmenden   Ringe an.   jedem Ende eine Feder angeordnet ist. Die Kolbentrommel ist in an sich bekannter Art derart mit der   unverrückbar   gelagerten Welle verbunden, dass sie dieser gegenüber eine'geringe'Verschiebung erfahren kann. 



   Die Maschine nach der Erfindung ist auf der Zeichnung im Schnitt veranschaulicht.   a   ist das zylindrische Maschinengehäuse, in dem die exzentrisch gelagerte Kolbentrommel b 
 EMI1.1 
 Kolbentrommel angeordnet sind. Die   Federn/* bewirken, dass   die   Kolbe11trommel   b stets in gleichem Abstand von den beiden Gehäusedeckel c gehalten wird. Statt in die Kolbentrommel können die Lager e auch in die Zylinderwände eingelassen sein.

  Rotary piston machine.



   In rotary piston machines with a piston drum mounted eccentrically in the cylinder and a slide piston that can be moved radially in this, on the one hand, a sufficient seal between the end faces of the piston drum and the cylinder cover and, on the other hand, a possible. To ensure smooth running, hardened races have already been inserted into the cylinder cover, on which similar hard rings located on the front ends of the piston drum run. Furthermore, the wedge connection between the piston drum and the shaft which is immovable with respect to the cylinder in the axial direction has been designed so that the piston drum can be displaced with respect to the shaft within the required small limits.



   The means mentioned have not always been able to prevent one-sided contact of the piston rod] on a cylinder wall and thus prevent corrosion of these parts.



   The subject of the invention is now such a machine in which the starting of the piston drum on the cylinder wall is prevented by the fact that between the ends of the piston drum and the rings absorbing the starting pressure. a spring is arranged at each end. The piston drum is connected in a manner known per se to the immovably mounted shaft in such a way that it can experience a “slight” displacement with respect to it.



   The machine according to the invention is illustrated in the drawing in section. a is the cylindrical machine housing in which the eccentrically mounted piston drum b
 EMI1.1
 Piston drum are arranged. The springs / * have the effect that the piston drum b is always kept at the same distance from the two housing covers c. The bearings e can also be embedded in the cylinder walls instead of in the piston drum.
