Abstract

Die Erfindung betrifft eine mobile Arbeitsmaschine (10) mit mehreren ersten hydraulischen Verbrauchern (11; 13) und einem zweiten hydraulischen Verbraucher (41), wobei die ersten Verbraucher (11; 13) einen Fahrantrieb und/oder einen Arbeitsantrieb der mobilen Arbeitsmaschine (10) umfassen, wobei eine erste Pumpe (30) mit verstellbarem Verdrängungsvolumen Hydraulikfluid aus einem Tank (16) zu den ersten Verbrauchern (11; 13) fördern kann, wobei eine zweite Pumpe (32) Hydraulikfluid aus dem Tank (16) zu dem zweiten Verbraucher (41) fördern kann, wobei ein Verbrennungsmotor (40) vorgesehen ist, der mit der ersten und der zweiten Pumpe (30; 32) in Drehantriebsverbindung steht, wobei der zweite Verbraucher (41) ein drehbares Lüfterrad (42) zur Kühlung des Verbrennungsmotors (40) antreibt. Erfindungsgemäß ist ein Druckspeicher (50) zum Speichern von unter Druck stehendem Hydraulikfluid vorgesehen, wobei der Druckspeicher (50) derart in Fluidverbindung mit den ersten Verbrauchern (11; 13) steht, dass Hydraulikfluid, welches von wenigstens einem ersten Verbraucher (13) zurückfließt, in den Druckspeicher (50) fließen kann, nicht aber umgekehrt, wobei der Druckspeicher (50) derart in Fluidverbindung mit dem zweiten Verbraucher (41) steht, dass Hydraulikfluid von dem Druckspeicher (50) zum zweiten Verbraucher fließen kann.
