Abstract

Eine Hydraulikanlage für Baumaschinen, insbesondere Radlader, Schlepper u. dgl. ist mit einem über Hydraulikzylinder (3) betätigbaren Arbeitswerkzeug, insbesondere Ladeschaufel, versehen, wobei zur Betätigung der Hydraulikzylinder (3) eine von einer Druckquelle über ein Steuerventil (2) zu den Hydraulikzylindern (3) führender Hauptleitung (1) vorgesehen ist, von der nach dem Steuerventil (2) eine zu mindestens einem Hydraulikspeicher (12) führende Verbindungsleitung (13) abzweigt, in der ein schaltbares Absperrventil (14) angeordnet ist. Es ist eine das Absperrventil (14) überbrückende Fülleitung (19, 20) vorgesehen, die die Hauptleitung (1) mit dem Hydraulikspeicher (12) verbindet. in der Fülleitung (19, 20) ist ein Druckminderventil (21) angeordnet.
