Abstract
A system for charging and discharging at least one hydraulic accumulator () can be connected to a valve control device (). The valve control device () has at least one logic valve (). A shuttle valve () and a hydraulically operated switching valve () are also provided. The valves () are interconnected such that the hydraulically actuatable switching valve () compares the accumulator pressure (p) to a minimum accumulator pressure (p) that can be adjusted via the control pressure setting of this switching valve ().
