 exzenter an der mit höherem Gegendruck arbeitenden Zylinderseite grösseren-Durchmesser, als der   Steuerexzenter   an der mit geringerem Gegendruck arbeitenden Zylinderseite, so dass die beiden Einlassventile dementsprechend verschieden grossen Hub erhalten. In dem in Fig. 3 der Zeichnung dargestellten Steuerungsdiagramm ist b die Exzentrizität der Steuerung an der mit geringerem Gegendruck arbeitenden Zylinderseite,   1I die Exzentrizität   der Steuerung an der mit grösserem   Gegendruck arbeitenden Zylinderseite, a   und ss sind die etwas verschiedenen Voreilwinkel.

   Durch die annähernd gleiche Leistung. beider Zylinderseiten hat die Maschine ruhigen,   gleichmässigen   Gang und   ermöglicht   eine genaue Regelung. Die Regelung der Maschine erfolgt nur rom Geschwindigkeitsregler aus, und zwar wirkt ein Regler gleichzeitig auf die Steuerung beider Zylinderseiten derart ein, dass der Füllungsgrad beider Zylinderseiten sich stets in demselben Verhältnis ändert. Das wird z. B. bei Verwendung eines Achsenreglers dadurch erzielt, dass die Scheitelkurven, wie Fig. 3 zeigt, vorn und hinten derart verschieden   ausgeführt

   Fig. 4 und 5 der Zeichnung zeigen noch die zugehörigen Diagramme, aus welchen ersichtlich ist, dass das Diagramm mit grösserem Gegendruck um so viel grösseren Füllungsgrad hat als das Diagramm mit geringerem Gegendruck, dass beide ungefähr den gleichen Flächeninhalt haben und somit die Leistung auf beiden Zylinderseiten ungefähr dieselbe ist. 



   PATENT-ANSPRÜCHE :
1. Gegendruckdampfmaschine, dadurch gekennzeichnet, dass zum Zwecke der Entnahme von Abdampf verschieden hohen Überdruckes beide Zylinderseite verschiedenen Gegendruck erhalten und der Füllungsgrad der unter höherem Gegendruck arbeitenden Zylinderseite um so viel grösser bemessen wird, dass beide Zylinderseiten gleiche oder annähernd gleiche Leistung ergeben.

 eccentric on the larger-diameter cylinder side working with higher counterpressure than the control eccentric on the cylinder side working with lower counterpressure, so that the two inlet valves accordingly have different stroke sizes. In the control diagram shown in Fig. 3 of the drawing, b is the eccentricity of the control on the cylinder side working with lower counterpressure, 1I the eccentricity of the control on the cylinder side working with greater counterpressure, a and ss are the slightly different advance angles.

   With almost the same performance. Both cylinder sides, the machine has a smooth, even gait and enables precise control. The machine is only regulated by means of a speed controller, and one controller acts simultaneously on the control of both cylinder sides in such a way that the degree of filling of both cylinder sides always changes in the same ratio. This is z. B. when using an axis controller is achieved in that the apex curves, as shown in FIG. 3, are designed so differently at the front and rear
 EMI2.1
 



   4 and 5 of the drawing also show the associated diagrams, from which it can be seen that the diagram with greater counterpressure has so much greater degree of filling than the diagram with lower counterpressure that both have approximately the same area and thus the performance on both Cylinder sides is approximately the same.



   PATENT CLAIMS:
1. Counterpressure steam engine, characterized in that for the purpose of extracting exhaust steam of different levels of overpressure, both cylinder sides receive different counterpressures and the degree of filling of the cylinder side working under higher counterpressure is so much larger that both cylinder sides give the same or approximately the same performance.
