    Regel-oder Antriebsein'ichtung   mit   Itydraulischer Übettraguug.

 <Desc/Clms Page number 2> 

 Die   Überdruckventile"M und   können selbstverständlich statt in den Zuleitungen zum Servomotor auch am Gehäuse desselben selbst angeordnet sein. 



   Gegebenenfalls können die   Überdruckventile   auch zugleich mit dem Steuerorgan des Servomotors vereinigt bzw. in diesem untergebracht sein. Fig. 2 zeigt eine entsprechende Ausführungsform. Im Steuer- 
 EMI2.1 
 Flüssigkeitskammern des Servomotors 3 in Verbindung stehen. 



   Die Überdruckventile 10 und 11 können auch, wie Fig. 3 zeigt, im Arbeitskolben 15 des Servomotors angeordnet sein. In diesem Fall findet bei Ansprechen eines der Ventile ein Druckausgleich zwischen den beiden durch den Kolben 15 getrennten Kammer statt, so dass kein Unterdruck in der jeweils ihr Volumen vergrössernden Kammer entsteht. 



   PATENT-ANSPRÜCHE :
1. Regel-oder Antriebseinrichtung mit hydraulischer Übertragung, insbesondere hydraulischer Regler für Drehtransformatoren, dadurch gekennzeichnet, dass der bzw. die Arbeitsräume (Arbeitszylinder od.   dgl.)   des hydraulischen Servomotors mit Überdruckventilen verbunden sind, die   unabhängig von   der Steuervorrichtung des Servomotors eine Druckentlastung in diesem ermöglichen.

    Control or drive device with hydraulic transmission.
 EMI1.1
 

 <Desc / Clms Page number 2>

 The pressure relief valves "M and" can of course be arranged on the housing itself instead of in the feed lines to the servomotor.



   If necessary, the pressure relief valves can also be combined with the control element of the servomotor or housed in it. Fig. 2 shows a corresponding embodiment. In the tax
 EMI2.1
 Liquid chambers of the servo motor 3 are in communication.



   The pressure relief valves 10 and 11 can also, as FIG. 3 shows, be arranged in the working piston 15 of the servo motor. In this case, when one of the valves responds, a pressure equalization takes place between the two chambers separated by the piston 15, so that no negative pressure arises in the chamber increasing its volume.



   PATENT CLAIMS:
1. Control or drive device with hydraulic transmission, in particular hydraulic controller for rotary transformers, characterized in that the working space or spaces (working cylinder or the like) of the hydraulic servomotor are connected to pressure relief valves which, independently of the control device of the servomotor, relieve pressure enable this.

2. Ausführungsform nach Anspruch 1, dadurch gekennzeichnet, dass das oder die Überdruck- ventile in den Flüssigkeitsleitungen zwischen Servomotor und dessen Steuerorgan (Steuerzylinder) angeordnet sind. 2. Embodiment according to claim 1, characterized in that the pressure relief valve or valves are arranged in the fluid lines between the servomotor and its control element (control cylinder). 3. Ausführungsform nach Anspruch 1, dadurch gekennzeichnet, dass die Überdruckventile mit dem Steuerorgan des Servomotors (Steuerkolben, Steuerventil) vereinigt bzw. in diesem untergebracht sind. 3. Embodiment according to claim 1, characterized in that the pressure relief valves are combined with the control element of the servomotor (control piston, control valve) or are housed in this. 4. Ausführungsform nach Anspruch 1, dadurch gekennzeichnet, dass die Überdruckventile im Arbeitskolben des Servomotors angeordnet sind. EMI2.2 4. Embodiment according to claim 1, characterized in that the pressure relief valves are arranged in the working piston of the servo motor. EMI2.2
