Abstract

Die Erfindung betrifft ein hydraulisch betriebenes Sicherheitsventil das mit zwei elektromagnetisch betätigbaren Vorsteuerventilen (12, 14) ausgerüstet ist. Das Sicherheitsventil hat zwei koaxiale gegenläufig zu­ einander betätigbare Ventilkörper (18, 20). Eines der beiden Vorsteuerventile ist als Proportional-Druckdifferenzventil ausgebildet und einer der beiden Ventilkörper ist mit Feinsteuerkerben versehen. Hierdurch ist es möglich, bei entsprechender Ansteuerung des Proportional-­ Druckdifferenzventiles über die Feinsteuerkerben einen entsprechenden Querschnitt vom Pumpenanschluß (P) zum Arbeitsanschluß (A) bzw. vom Arbeitsanschluß zum Tankanschluß (R) freizugeben, wodurch an einem an den Arbeitsanschluß angeschlossenen Verbraucher, z.B. einem Zylinder oder einem Motor, die Geschwindigkeit und der Druckanstieg gesteuert werden können.
