Abstract

Es wird eine elektrohydraulische Steuervorrichtung (10; 60) vorgeschlagen, bei der eine 4/2-Funktion für zwei Volumenströme zu einem doppelt wirkenden Stellmotor mit einem Sitzventil (11; 61) für den die Last absichernden Ablaufstrom (B nach R) und mit einem Schieberventil (12; 62) für den Zulaufstrom (P nach A) realisiert wird. Die von der Kraft eines Proportionalmagneten (15) gegen eine Federkraft verstellten Ventilglieder beider Ventile stehen miteinander in Wirkverbindung und weisen zwei Justiereinrichtungen (52, 53; 63, 64) auf, mit denen die Überdeckungen der Steuerkanten (23, 46) für beide Volumenströme und damit deren Kennlinien justierbar sind.
