Abstract

Offenbart sind ein hydraulisches Zweikreissystem zur Ansteuerung von Verbrauchern (12,14) und ein Verfahren zum Ansteuern von Verbrauchern eines hydraulischen Zweikreissystems, wobei die beiden Kreise (1,2) über eine Zusammenschaltventilanordnung (4) miteinander verbindbar sind, so dass die Verstellpumpe (8,10) eines Kreises (1,2) Druckmittel in den anderen Kreis (2,1) summiert. Das Zweikreissystem hat eine Deaktivierungseinrichtung (β), über die die Summierung deaktiviert wird, wenn der Druckmittelbedarf in dem hinzugeschalteten Kreis kleiner als der maximale Pumpenförderstrom und größer als ein Umschalt- Druckmittelbedarf ist. Dieser kann beispielsweise bei etwa 80% des maximalen Pumpenförderstroms liegen.
