Abstract

Die Erfindung beschreibt eine Regelvorrichtung für zumindest zwei mit einem Druckmedium (6), insbesondere Hydrauliköl (7), betriebene Arbeitsgeräte (2, 3), z.B. Bergeschere (4), Bergespreizer (7), etc., mit je einem Arbeitsgerät (2, 3), einem Versorgungskreis (10, 11) für das Druckmedium (6) und mit zumindest einer Druckerzeugungsvorrichtung (9). In den Versorgungskreisen (10, 11) für die Arbeitsgeräte (2, 3) ist zumindest je eine durch ein Steuerventil (23, 24) gebildete Steuervorrichtung (15) angeordnet und die Steuerventile (23, 24) stehen über zumindest einen Verbindungskanal (25) oder eine Verbindungsleitung bedarfsweise in Strömungsverbindung.
