Abstract
Description
Durch entsprechende Auslenkung der Steuerdruckgeber 26, 29, 32 wird in den entsprechenden Steuerdruckleitungen 27a, 27b, 30a, 30b, 33a, 33b ein das zugeordnete Wegeventil 11, 12, 13 beaufschlagender Steuerdruck erzeugt, wobei an den Meßblenden 14, 15, 16 entsprechend der Höhe des jeweiligen Steuerdrucks Öffnungen gebildet werden, die die Bewegungsgeschwindigkeit des zugeordneten Verbrauchers 8, 9, 10 bestimmen. Der höchste Lastdruck der Verbraucher 8, 9, 10 wird mittels der Lastdruckmeldezweigleitungen 17, 18, 19 in die Lastdruckmeldeleitung 20 gemeldet und beaufschlagt den Pumpenregler, wodurch die Pumpe 2 den an den Meßblenden angeforderten Druckmittelstrom fördert bei einem Förderdruck, der um eine bestimmte Druckdifferenz über dem höchsten Lastdruck liegt. Im normalen Betrieb werden somit die Verbraucher 8, 9, 10 mit den an den Meßblenden 14, 15, 16 eingestellten Bewegungsgeschwindigkeiten betrieben.
