Abstract

Ein Hydraulikversorgungssystem zur Versorgung eines hydraulischen Verbrauchers (12) mit wenigstens einem Verbrauchsbereich (14, 16) mit Druckfluid umfasst eine Druckfluid aus einem Reservoir (26) in eine Hauptdruckleitung (24) speisende Druckfluidquelle (18) und in Zuordnung zu jedem mit Druckfluid zu versorgenden Verbrauchsbereich (14, 16) eines hydraulischen Verbrauchers (12) ein durch einen Steuerfluiddruck zu verstellendes Hauptsteuerventil (34, 36) zum Herstellen und Unterbrechen der Verbindung zwischen der Hauptdruckleitung (24) und einem Verbrauchsbereich (14, 16) sowie ein Vorsteuerventil (38, 40) zum Anlegen des Steuerfluiddrucks an das Hauptsteuerventil (34, 36), wobei das Vorsteuerventil über einen Druckminderer (42) mit einem Eingangsdruck gespeist wird, der unter dem Fluiddruck in der Hauptdruckleitung (24) liegt.
