| 摘要 |
The invention relates to a valve arrangement for actuating a piston cylinder arrangement (13), comprising a pilot control valve arrangement and a main control valve arrangement, wherein both the pilot control and main control valve arrangement comprise a 3/2-way valve as a pilot control valve (21) and as a main control valve (20), each valve comprising a control-pressure, high-pressure, and low-pressure connection. Said connections are connected to each other such that the main control valve (20) is controlled via the control-pressure connection of the pilot control valve (21) and the pressures on the control-pressure connection and on the high-pressure connection of both valves (20), (21) are statically inverted relative to each other. The 3/2-way valves (20, 21) are designed as seat valves and are only hydraulically connected to each other. |
