Abstract

Es wird ein Ventil zum Steuern von Flüssigkeiten vorgeschlagen, mit einem in einem Ventilkörper (5) axial bewegbaren Ventilglied (3), mit einer als hydraulische Übersetzung arbeitenden hydrualikkammer (12), und mit einer Befülleinrichtung (15) zum Ausgleich von Leckageverlusten, welche mit einem Hochdruckbereich (14) und einem Niederdruckbereich (13) des Ventils verbunden ist und einen Drosselkörper (18) aufweist. Erfindungsgemäss ist vorgesehen, dass der Drosselkörper (18) in Abhängigkeit von einem im Niederdruckbereich (13) herrschenden Druck derart beweglich ist, dass eine Befüllung der Hydraulikkammer (12) mit Flüssigkeit erfolgt.
