Patentansprüche:Patent claims: 1. Öldrucksteuerungseinrichtung für Dampfturbinen, dadurch gekennzeichnet, daß die Steuerungseinrichtung mit einer Sperrvorrichtung versehen ist, welche beim Stillsetzen der Maschine die Steuerung offenhält.1. Oil pressure control device for steam turbines, characterized in that that the control device is provided with a locking device, which Keeps the control open when the machine is shut down. 2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß der Kraftkolben der Steuerung beim Stillsetzen der Maschine durch eine selbsttätig eingreifende Sperrvorrichtung an einer weiteren Bewegung gehindert wird.2. Device according to claim 1, characterized characterized in that the power piston of the control when stopping the machine is prevented from further movement by an automatically engaging locking device. 3. Einrichtung nach Anspruch 1 und 2, dadurch- gekennzeichnet, daß die Sperrvorrichtung in Abhängigkeit vom Steuer-Öldruck in und außer Tätigkeit gesetzt wird.3. Device according to claim 1 and 2, characterized in that the locking device is set in and out of action depending on the control oil pressure. 4. Einrichtung nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Sperrvorrichtung dem Einfluß eines Unterdrehzahlreglers untersteht.4. Device according to claim 1 and 2, characterized in that the locking device is subject to the influence of an underspeed controller.
