Wenn auch die zur Betätigung der eigentlichen Steuerung dienenden Steuerwellen in gewisser Verbindung zueinander stehen, so sind sie doch in ihrer Bewegung voneinander vollständig unabhängig. 



   Die Bauart der ganzen Umsteuerungsvorrichtung ist eine äusserst gedrungene und sehr einfache, da alle Steuerorgane in gleicher Flucht liegen und in einem einzigen Gehäuse untergebracht sind. Die Reibung zwischen den konzentrischen Steuerwellen e   und q ist   gering, da für diese nur der Unterschied der   Schwingungsausschläge   der Steuerwelle in Betracht kommt. 



  Ferner wird durch die Lagerung der Steuerwellen in dem rohrförmigen Gehäuse m ihre gute Abdichtung gewährleistet. 



   Die Steuerscheiben für die verschiedenen Zylinder können auf die Steuerwellen in beliebiger Weise aufgesetzt werden, je nach der für die Regelung der Ein-und Ausströmung der Hochund Niederdruckzylinder gewählten Regelungsweise. Auch können beliebig viel konzentrische Steuerwellen verwendet werden ; indem beispielsweise die erste auf der exzenterfreien Seite der Maschine gelagerte Steuerwelle als   Vollwelle ausgeführt   ist und über die sämtlichen Zylinder an die andere Seite der Maschine führt, während die folgenden Steuerwellen als Hohlwellen ausgebildet sind und sich auf der Vollwelle sowie gegenseitig stützen.

Even if the control shafts used to actuate the actual controls are connected to one another to a certain extent, their movement is completely independent of one another.



   The design of the entire reversing device is extremely compact and very simple, since all control elements are in the same alignment and are housed in a single housing. The friction between the concentric control shafts e and q is low, since only the difference in the oscillation deflections of the control shaft is taken into account.



  Furthermore, the storage of the control shafts in the tubular housing m ensures their good sealing.



   The control disks for the various cylinders can be placed on the control shafts in any way, depending on the control mode selected for regulating the inflow and outflow of the high and low pressure cylinders. Any number of concentric control shafts can also be used; For example, the first control shaft mounted on the eccentric side of the machine is designed as a solid shaft and via which all cylinders lead to the other side of the machine, while the following control shafts are designed as hollow shafts and support each other on the solid shaft.

PATENT. ANSPRUCH : Steuerwellen-Anordnung für Ventilsteuerungen bei aus mehreren Zylindergruppen bestehenden Dampfmaschinen, bei denen die Kurbeln der einzelnen Gruppen auf eine gemeinschaft- liche Wolle wirken und zueinander um einen anderen Winkel als 18U versetzt sind und die Be- tätigung dor Ventile vermittels auf den Steuerwellen sitzender Kurvenscheiben erfolgt, dadurch EMI2.1 seite aus durch auf der Kurbelwelle sitzende Exzenter (n, b) ihre schwingende Bewegung in bekannter Weise erhalten, wobei die Exzenter von einer gemeinschaftlichen Umsteuerungsvorrichtung (z) betätigt werden. PATENT. CLAIM : Control shaft arrangement for valve controls in steam engines consisting of several cylinder groups, in which the cranks of the individual groups act on a common wool and are offset from one another by an angle other than 18U and the actuation of the valves takes place by means of cams on the control shafts , thereby EMI2.1 side received their oscillating motion in a known manner by eccentrics (n, b) seated on the crankshaft, the eccentrics being actuated by a common reversing device (z).
