Abstract

Offenbart sind ein Verfahren und eine Steueranordnung zur Ansteuerung hydraulischer Verbraucher, die jeweils über eine verstellbare Messblende und eine Druckwaage mit einer Verstellpumpe (4) oder einem Tank (T) verbunden sind. Die Ansteuerung der verstellbaren Messblende zunächst eines nachgeordneten Verbrauchers erfolgt erfindungsgemäss in Abhängigkeit vom Ansteuerdruck der einem Prioritätsverbraucher zugeordneten einstellbaren Messblende, wobei im Unterversorgungsbereich die Druckmittelversorgung des oder der nachgeordneten Verbraucher zurückgefahren wird, so dass eine Versorgung des Prioritätsverbrauchers gewährleistet ist und die Funktion der nebengeordneten Verbraucher mit eingeschränkter Leistung möglich bleibt.
