 Dies ist in Fig. 2 beispielsweise zur Darstellung gebracht. 



  Der Kolbenschieber k ist bei diesem   Ausführungsbeispiel   der   Erfindung   durch Zwischen-

 artigen Durchbrechungen des Schiebers für den Auslass doppelt so gross gewählt als in der vorletzten Stufe. Der Auslasskanal ist hier für beide Zylinderseiten gemeinsam und in der Mitte des Kolbenhubes angeordnet. 



   Wie aus den vorstehenden Ausführungen zu ersehen ist, wird durch die Erfindung der theoretischen Forderung nach einem in bestimmtem Verhältnis zum Kolbenhubvolumen stehenden Kanalquerschnitt für beide Zylinder bei unabhängiger Dampfverteilung mit kleinstem zulässigen Schieberhub und kleinstem schädlichen Raum mit nur einem Schieber Rechnung getragen.

   l.   Kolbenschiebersteuerung für Verbund-Dampfmaschinen, bei denen ein gemeinsamer, mit kanalartigen Durchbrechungen am Umfang und verschiedenen überdeckungen versehener Kolbenschieber, dessen Innenraum als Aufnehmer dient, den Dampfauslass des kleineren Zylinders

 This is shown in FIG. 2, for example.



  The piston valve k is in this embodiment of the invention by intermediate
 EMI2.1
 like openings in the slide for the outlet chosen to be twice as large as in the penultimate stage. The exhaust port is common for both cylinder sides and is located in the middle of the piston stroke.



   As can be seen from the above, the theoretical requirement for a channel cross-section in a certain ratio to the piston stroke volume for both cylinders with independent steam distribution with the smallest permissible slide stroke and the smallest harmful space with only one slide is taken into account by the invention.
 EMI2.2
   l. Piston valve control for compound steam engines in which a common piston valve with channel-like openings on the circumference and various overlaps, the interior of which serves as a sensor, is the steam outlet of the smaller cylinder

Claims (1)

2, Kolbenschiebersteuerung nach Anspruch 1, dadurch gekennzeichnet, dass im letzten Zylinder (Z) auch der an beliebiger Stelle im Kolbenlauf angeordnete Dampfauslass (h) durch denselben Kolbenschieber gesteuert wird, der den Auslass (f) des vorletzten Zylinders (z) und den Dampfeinlass (g) des letzten Zylinders steuert, derart, dass die Zahl der Eröffnungen für den Auslass des letzten Zylinders eine grössere ist als die Zahl der Eröffnungen für den Auslass des vor- letzten Zylinders (Fig. 2). 2, piston valve control according to claim 1, characterized in that in the last cylinder (Z) the steam outlet (h) arranged at any point in the piston barrel is controlled by the same piston valve that controls the outlet (f) of the penultimate cylinder (z) and the steam inlet (g) of the last cylinder controls such that the number of openings for the outlet of the last cylinder is greater than the number of openings for the outlet of the cylinder before the last (FIG. 2).
