 einem Grunde der Öldruck im-Servomotor der Steuerung fehlen sollte, durch Herstellung der Verbindung des Raumes d mit der Leitung   I   die Nadel a geschlossen wird. 



   Durch richtige Wahl des Durchmessers für den Ausgleichskolben c sowie des Ortes und der Art der Anzapfung der auf diesen Kolben c zum Einwirken zu bringenden Druckflüssigkeit können die Kolbenverstellkraft und die von den Dichtungsmanschetten herrührende Reibungskraft derart ausgeglichen werden, dass die Nadel a in jeder Stellung ihres Hubes mit der geringstmöglichen Kraft verstellt und die Regulierarbeit des die Nadel betätigenden Geschwindigkeitsregulators auf das grösstmögliche Minimum gebracht werden kann. 



   Die beschriebene Anordnung lässt sich selbstverständlich auch in Verbindung mit Düsen mit Handregulierung oder mechanischem Antrieb anwenden. 



   PATENT-ANSPRÜCHE :
1. Wasserturbine mit mindestens einer durch eine Nadel regelbaren Düse und einem auf dem Nadelschaft sitzenden, zum Ausgleich der auf die Nadel wirkenden Kräfte dienenden Kolben, dadurch gekennzeichnet, dass auf den Ausgleichskolben der jeweils in der Nähe der Austrittsöffnung des Düsenmündungsstückes herrschende Druck einwirkt.

 <Desc / Clms Page number 2>

 one reason the oil pressure in the servomotor of the control should be missing, the needle a is closed by establishing the connection between the space d and the line I.



   By correct choice of the diameter for the compensating piston c and the location and type of tapping of the hydraulic fluid to be brought into action on this piston c, the piston adjusting force and the frictional force resulting from the sealing sleeves can be compensated in such a way that the needle a is in every position of its stroke adjusted with the least possible force and the regulating work of the speed regulator actuating the needle can be brought to the greatest possible minimum.



   The arrangement described can of course also be used in conjunction with nozzles with manual control or mechanical drive.



   PATENT CLAIMS:
1. A water turbine with at least one nozzle adjustable by a needle and a piston seated on the needle shaft to compensate for the forces acting on the needle, characterized in that the pressure prevailing in the vicinity of the outlet opening of the nozzle mouth piece acts on the compensating piston.

Claims (1)

2. Wasserturbine nach. Anspruch 1, dadurch gekennzeichnet, dass durch eine Leitung, welche eine Verbindung zwischen einer Stelle in der Nähe der Austrittsöffnung des Düsenmündungsstückes und einem auf der einen Seite vom Ausgleichkolben begrenzten und auf der andern Seite gegen das Düsenzuflussrohr abgedichteten Raum herstellt, Druckwasser aus dem Düsenmündungsstück in den genannten Raum gelangen kann. 2. Water turbine after. Claim 1, characterized in that through a line which creates a connection between a point in the vicinity of the outlet opening of the nozzle mouthpiece and a space bounded on one side by the compensating piston and sealed against the nozzle inlet pipe on the other side, pressurized water from the nozzle mouthpiece into can reach the said room. 3. Wasserturbine nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass in die zum Zuführen EMI2.1 EMI2.2 3. Water turbine according to claims 1 and 2, characterized in that in the for feeding EMI2.1 EMI2.2
