Abstract (en)
[origin: WO2015082321A1] Disclosed is a hydraulic arrangement with an adjustable hydraulic machine (2) and a control valve (64), which is assigned to a first operating mode of the hydraulic machine, in particular motor operation, and the control of which can be used to supply pressure medium to an adjusting chamber of an adjusting cylinder of the hydraulic machine. The arrangement also has, for a second operating mode of the hydraulic machine, in particular for pump operation, a second control valve (66), for supplying pressure medium to the adjusting chamber. By actuating a means (46, 146) of the arrangement, one of the control valves can be activated or deactivated and the other can correspondingly be deactivated or activated, thus allowing the control to take place in the different operating modes with different effective principles and/or control parameters.
