Abstract: The valve arrangement for the activation of a structural element has three inlet switching valves through which a pressure-loaded medium can be conducted. These inlet switching valves are connected on their inflow side to a pressure supply by inflow lines and are arranged parallel to one another in flow terms. Moreover, the valve arrangement has a connection element, which is connected to outflow sides of all the inlet valves by pressure lines. A control line acted upon by the medium is connected to the pressure supply. The three switching-valve groups can be activated by the control line, and in each case two switching valves and in each case one inlet switching valve are assigned to each switching-valve group. A activation valve can be interposed in each case between a switching-valve group and the control line. Three outflow lines for the medium can be arranged between an outflow location for the medium and the connection element.
