Abstract

Eine Pumpe fördert Druckflüssigkeit über ein Filterelement zu den Verbrauchern. Um bei kalter Druckflüssigkeit mit entsprechend höherer Viskosität das Filterelement zu schützen und zu gewährleisten, daß den Verbrauchern ausreichend Druckflüssigkeit zur Verfügung steht, wird unterhalb einer zuvor definierten Temperatur die Druckflüssigkeit direkt von der Pumpe und oberhalb einer zuvor definierten Temperatur die Druckflüssigkeit über das Filterelement zu den Verbrauchern geleitet. Hierzu wird über ein temperaturabhängiges Element (1) eine Verbindung von der Pumpe (7) zu den Verbrauchern (8) abhängig von der Temperatur geschaffen oder verschlossen. Treten vor dem Filterelement Druckspitzen auf, so werden diese über ein Rückschlagventil (6) abgebaut, um das Filterelement zu schützen.
