Abstract
A hydraulic system includes at least one pump assembly and a switching device which includes at least two switch positions. The switching device is configured such that on operation of the pump assembly in a first operating condition, the switching device is held in a stable manner in each of the at least two switch positions in each case by the hydraulic forces in the system. In a second operating condition of the pump assembly, the switching device is moved from a first switch position into a second switch position, assisted by switching energy stored in the first operating condition. The hydraulic system is configured such that in the first operating condition, the switching energy is stored independently of a switching-over of the switching device between the switch positions. A method is provided for operating such a hydraulic system.
