Abstract

Es wird eine hydraulische Anordnung und ein Verfahren für eine solche vorgeschlagen. In der hydraulischen Anordnung ist wenigstens ein Druckspeicher (32) für eine hydraulische Flüssigkeit, wenigstens ein Hydraulikzylinder (10) mit wenigstens einer druckbeaufschlagbaren Kammer (12), eine Verbindungsleitung (34), anhand welcher der wenigstens eine Druckspeicher (32) mit der wenigstens einen Kammer (12) verbindbar ist, und eine Steuereinheit (40) vorgesehen.A hydraulic arrangement and a method for such is proposed. In the hydraulic arrangement, at least one pressure accumulator (32) for a hydraulic fluid, at least one hydraulic cylinder (10) with at least one pressureable chamber (12), a connecting line (34), based on which the at least one pressure accumulator (32) with the at least one Chamber (12) is connectable, and a control unit (40) is provided.

Um eine elektronische Rohrbruchsicherung zu ermöglichen, wird vorgeschlagen, dass in der Verbindungsleitung (34) wenigstens ein Schließventil (36) und ein druckabhängiger Signalgeber (38), insbesondere ein Druckschalter oder Drucksensor angeordnet sind. Wenn ein Druckabfall in der Verbindungsleitung (34) auftritt, wird anhand des Signalgebers (38) eine Signaländerung erzeugt, woraufhin die Steuereinheit (40) das Schließventil (36) schließt.

Figure imgaf001
In order to enable an electronic pipe rupture protection, it is proposed that in the connecting line (34) at least one closing valve (36) and a pressure-dependent signal generator (38), in particular a pressure switch or pressure sensor are arranged. When a pressure drop occurs in the connecting line (34), a signal change is generated by means of the signal transmitter (38), whereupon the control unit (40) closes the closing valve (36).
