Abstract

Die Hydraulikanlage nach Figur 1 besteht aus einem von einer Hochdruckpumpe (10) gespeisten Hauptverbraucher (13) und einem von einer Niederdruckpumpe (16) gespeisten Nebenverbraucher (19). Die Niederdruckpumpe (16) wird von einer in der Förderleitung (12) des Hauptkreises angeordne­ ten Turbine (15) angetrieben. Beide Pumpen fördern Druck­ mittel aus einem Behälter (11), das diesem wiederum im offe­ nen Kreis zuströmt. Die Niederdruckpumpe ist zweckmä­ ßigerweise eine Konstantpumpe, z.B. eine Zahnradpumpe, die über die Turbine bis zu deren Stillstand mit einem weitge­ hend konstanten Drehmoment angetrieben wird. Der Neben­ kreis wird auf diese Weise mit der tatsächlich gebrachten Druckmittelmenge versorgt. Eine derartige Anlage ist billig und verursacht geringe Leistungsverluste.
