Abstract

Die Erfindung betrifft ein Druckmittelsystem, insbesondere ein Hydrauliksystem, mit einer Fluidpumpe (1) zum Fördern eines Antriebsfluids mit einem bestimmten Förderstrom und einem bestimmten Fluiddruck (PIST), einer Steuereinheit (8), welche die Fluidpumpe (1) anschaltet oder abschaltet, um einen vorgegebenen Soll-Wert (PSOLL) des Fluiddrucks (PIST) einzustellen, wobei die Fluidpumpe (1) beim Abschalten einen trägheitsbedingten Nachlauf aufweist, so dass der Fluiddruck während des Nachlaufs der Fluidpumpe (1) noch ansteigt, während die Fluidpumpe (1) bereits abgeschaltet ist. Es wird vorgeschlagen, dass die Steuereinheit (8) beim Erhöhen des Fluiddrucks (PIST) auf den vorgegebenen Soll-Wert die Fluidpumpe (1) abschaltet bevor der Fluiddruck (PIST) den vorgegebenen Soll-Wert (PSOLL) erreicht hat. Weiterhin umfasst die Erfindung ein entsprechendes Betriebsverfahren.
