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. The switching valves of each outflow line can be actuated by different activation valves.

The invention claimed is: 1. Valve element for the activation of a structural element, comprising: three inlet switching valves, through which a pressure-loaded medium can be conducted and which are connected on their inflow side to a pressure supply by means of inflow lines and are arranged parallel to one another in flow terms; a connection element for the structural element, which connection element is connected to outflow sides of all the inlet switching valves by means of pressure lines; a control line acted upon by the medium connected to the pressure supply, three switching-valve groups can be activated by means of the control line, wherein two switching valves and one of the inlet switching valves are assigned to each switching-valve group, wherein an activation valve is interposed in each case between a switching-valve group and the control line, by means of which activation valve the switching actions of the switching valves and of the inlet valve of the corresponding switching-valve group are made possible; and three outflow lines for the medium, which are connected in parallel in flow terms, and are arranged between an outflow location for the medium and the connection element, wherein two switching valves are arranged in a series connection in each of the outflow lines, and wherein the switching valves of each outflow line are actuated by different activation valves. 2. Valve arrangement according to claim 1, wherein the medium is a gas or liquid. 3. Valve arrangement according to claim 1, wherein the structural element is a quick-acting shut-off valve or a safety device. 4. Valve arrangement according to claim 1, wherein the activation valve is a solenoid valve. 5. Valve arrangement according to claim 1, wherein the switching valves, the inlet valves and/or the activation valves have a return spring which, when the valve is in the inoperative state, keeps the latter in or brings the latter into a predetermined valve position. 6. Valve arrangement according to claim 1, wherein the switching valves, the inlet valves and the activation valves or the valves of a switching-valve group are arranged in a common housing. 7. Valve arrangement according to claim 1, wherein a pressure sensor is arranged in each pressure line connected to an inlet switching valve. 8. Valve arrangement according to claim 1, wherein a pressure sensor is arranged in each outflow line in the line portion between the two switching valves arranged in the respective outflow line. 9. Valve arrangement according to claim 1, wherein three bypass lines, with at least one throttle member in each bypass line, are arranged between the inflow lines and the outflow lines, and wherein the bypass lines are connected to the outflow lines in the region between the switching valves and the outflow location of the bypass lines. 10. Valve arrangement according to claim 1, wherein in each case one bypass line is connected to an outflow line, and wherein the connection point is arranged between the two switching valves in the respective outflow line. 11. Valve arrangement for the activation of a structural element, comprising: at least three inlet switching valves, through which a pressure-loaded medium can be conducted and which are connected on their inflow side to a pressure supply by means of inflow lines and are arranged parallel to one another in flow terms; a connection element for the structural element, which connection element is connected to outflow sides of all the inlet switching valves by means of pressure lines; a control line acted upon by the medium is connected to the pressure supply, wherein a first number of switching-valve groups can be activated by means of the control line, wherein the first number corresponds to the number of inlet-valve groups present, wherein a second number of switching valves and one of the inlet switching valves are assigned to each switching-valve group, wherein the second number is obtained from a result of the first number minus a whole number, insofar as the result is the number two or a greater number; and an activation valve interposed in each case between a switching-valve group and the control line, by means of which activation valve the switching actions of the switching valves and of the inlet valve of the corresponding switching-valve group are made possible, wherein the first number of outflow lines for the medium, which are connected in parallel in flow terms, are arranged between an outflow location for the medium and the connection element, wherein a second number of switching valves are arranged in a series connection in each of the outflow lines, and wherein the switching valves of each outflow line are actuated by different activation valves. 12. Valve arrangement according to claim 2, wherein the structural element is a quick-acting shut-off valve or a safety device. 13. Valve arrangement according to claim 2, wherein the activation valve is a solenoid valve. 14. Valve arrangement according to claim 3, wherein the activation valve is a solenoid valve. 15. Valve arrangement according to claim 2, wherein the switching valves, the inlet valves and/or the activation valves have a return spring which, when the valve is in the inoperative state, keeps the latter in or brings the latter into a predetermined valve position. 16. Valve arrangement according to claim 3, wherein the switching valves, the inlet valves and/or the activation valves have a return spring which, when the valve is in the inoperative state, keeps the latter in or brings the latter into a predetermined valve position. 17. Valve arrangement according to claim 4, wherein the switching valves, the inlet valves and/or the activation valves have a return spring which, when the valve is in the inoperative state, keeps the latter in or brings the latter into a predetermined valve position. 18. Valve arrangement according to claim 2, wherein the switching valves, the inlet valves and the activation valves or the valves of a switching-valve group are arranged in a common housing. 19. Valve arrangement according to claim 3, wherein the switching valves, the inlet valves and the activation valves or the valves of a switching-valve group are arranged in a common housing. 20. Valve arrangement according to claim 4, wherein the switching valves, the inlet valves and the activation valves or the valves of a switching-valve group are arranged in a common housing.
