Abstract

Es wird ein Ventil zum Steuern von Flüssigkeiten vorgeschlagen, mit einer Aktuator-Einheit (4) zur Betätigung eines Ventilglieds (3), welches einen ersten Kolben (9) und einen davon durch eine Hydraulikkammer (13) getrennten zweiten Kolben (11) aufweist, und das ein Ventilschliessglied (12) betätigt, welches einen Niederdruckbereich (16) mit Systemdruck von einem Hochdruckbereich (17) trennt. Zum Leckageausgleich ist eine mit dem Hochdruckbereich (17) verbindbare Befülleinrichtung (24) mit einem Hohlraum (25) vorgesehen, in dem ein Drosselkörper (26) derart angeordnet, dass in den Hohlraum (25) einenends des Drosselkörpers (26) eine zu dem Hochdruckbereich (17) führende Leitung (33) mündet und anderenends eine zur Hydraulikkammer (13) führende Systemdruck-Leitung (28) abzweigt. Der Systemdruck baut sich durch geometrische Festlegung einer Drosselbohrung (27) im Drosselkörper (26) und der Abmessungen des Kolbens (9), entlang dem der Systemdruck (p_sys) abgebaut wird, in Abhängigkeit eines vorliegenden Drucks im Hochdruckbereich auf.
