Abstract
A system for charging and discharging at least one hydraulic accumulator (10), which can be connected to a valve control device (12), wherein the valve control device (12) comprises at least one logic valve (14), is characterized in that a shuttle valve (16) and a switching valve (18) are also provided and the valves (14, 16, 18) are interconnected such that the hydraulically actuatable switching valve (18) compares the accumulator pressure (pA) to a minimum accumulator pressure (pA0) that can be adjusted via the control pressure setting of this switching valve (18).
