发明名称 HIGH VOLTAGE SWITCH
摘要 Exemplary embodiments relate to a valve arrangement for actuating a piston cylinder arrangement, that includes a pilot control valve arrangement and a main control valve arrangement, wherein both the pilot control and main control valve arrangement include a 3/2-way valve as a pilot control valve and as a main control valve. Each valve has a control-pressure, high-pressure, and low-pressure connection. Said connections are connected to each other such that the main control valve is controlled via the control-pressure connection of the pilot control valve and the pressures on the control-pressure connection of the pilot control valve and the pressures on the control-pressure connection and on the high-pressure connection of both valves, are statically inverted relative to each other. The 3/2-way valves are designed as seat valves and are only hydraulically connected to each other.
