   Wird nun das Schmieröl von einer gesonderten Pumpe geliefert, so ist natürlich wichtig, dass beim Versagen dieser Pumpe das Treibmittel auch abgestellt wird. Dies wird wie in Fig. 4 dargestellt, dadurch erreicht, dass das Ventil v gemäss der Erfindung durch ein Ventil k ersetzt ist, das dem Einflusse   d@s Schmieröles ausgesetzt   ist. Auf das Ventil k wirkt der hohe Öldruck, der von der Druckpumpe zum Kraftzylinder geliefert wird ; auf den Kolben   K   wirkt der niedrige Druck der gesonderten   Schmierölpumpe,   beide Pressungen halten sich im Gleichgewicht.

   Beim Versagen der Schmierölpumpe schiebt der Überdruck das Ventil k von seinem Sitz weg und stellt dadurch die Verbindung der Hochdruckleitung 11 mit der Leitung P her, welche in den Ablauf

   Der Kolben K ist mit dem Fliehkraftregler der Turbine verbunden, durch welchen das Abschlussorgan, in ähnlicher Weise wie der Hahn v bei der Fig. 3, bei Überschreitung einer bestimmten Tourenzahl so verstellt wird, dass der Raum unter dem Kolben e nach dem Freien geöffnet wird ; das Gestänge p ist hier auch so wie bei Fig. 3, dass die Maschine selbsttätig wieder

   PATENT-ANSPRÜCHE : 
1. Regelungsvorrichtung für Dampf-, Gas-oder Wasserturbinen, bei welcher nach Patent Nr. 28931 das   Haupteinlassorgan   während der Regelung durch das Regelungsorgan vom Öldruck offen gehalten wird, dadurch gekennzeichnet, dass das in die Zuleitung, welche das Drucköl zum Offnen des Haupteinlassorganes liefert, eingebaute Abschlussorgan derart von Hand oder automatisch gesteuert werden kann, dass es in einer Stellung das unter dem Kraftkolben befindliche Drucköl aus dem Kraftzylinder ins Freie strömen lässt, um das   Haupteinlassorgan   plötzlich zu schliessen.

   If the lubricating oil is now supplied by a separate pump, it is of course important that the propellant is also switched off if this pump fails. As shown in FIG. 4, this is achieved in that the valve v according to the invention is replaced by a valve k which is exposed to the influence of the lubricating oil. The high oil pressure, which is supplied to the power cylinder by the pressure pump, acts on the valve k; The low pressure of the separate lubricating oil pump acts on piston K; both pressures are kept in balance.

   If the lubricating oil pump fails, the overpressure pushes the valve k away from its seat and thereby connects the high-pressure line 11 with the line P, which into the drain

 inlet element o. This arrangement also allows the machine to be switched off if the lubricating oil fails if this is supplied by a separate pump.



   The piston K is connected to the centrifugal governor of the turbine, by means of which the closing element, in a similar manner to the cock v in FIG. 3, is adjusted when a certain number of revolutions is exceeded that the space under the piston e is opened to the outside ; the linkage p is here also as in Fig. 3, that the machine again automatically

The differential piston k K could also be set up for manual adjustment, like the valve v in FIG. 2.



   PATENT CLAIMS:
1. Control device for steam, gas or water turbines, in which, according to patent no. 28931, the main inlet element is kept open by the oil pressure during regulation by the control element, characterized in that in the feed line which supplies the pressurized oil to open the main inlet element , built-in closing element can be controlled manually or automatically in such a way that it allows the pressure oil located under the power piston to flow out of the power cylinder into the open in one position in order to suddenly close the main inlet element.

 

Claims (1)

2. Regelungsvorrichtung nach Anspruch 1, für Turbinen, bei welchen das Schmieröl von einer gesonderten Pumpe geliefert wird, dadurch gekennzeichnet, dass das Schmieröl auf das in die Zuleitung des Drucköles zum Offnen des Haupteinlassorganes eingebaute Abschlussorgan einwirkt und dasselbe in seiner Schlussstellung hält, beim Versagen der Schmierölpumpe aber das Abschlussorgan sich öffnet und das Druokmittel unter dem Kraftkolben ausströmen lässt. 2. Control device according to claim 1, for turbines in which the lubricating oil is supplied by a separate pump, characterized in that the lubricating oil acts on the closing element built into the supply line for the pressure oil to open the main inlet element and holds the same in its closing position in the event of failure of the lubricating oil pump but the closing element opens and the pressure medium can flow out under the power piston.
