As a result, and due to the force of the spring 4, a force acts on the sleeve element 13 in the direction of the outer valve seat 12 and presses the sleeve element 13 against the outer valve seat 12 in a closed position. The connection between the control chamber 30 and the anode channel 17 via the outer valve seat 12 is thus closed.
  • the magnet armature 8 is pressed against the inner valve seat 11 into a closed position and thus blocks the connection between the sleeve interior 130 or the control chamber 30 and the anode channel 17.
  • the diameter d on the inner valve seat 11 is selected to be so small that the inner valve seat 11 can be opened quickly and efficiently.
  • the force or the pulse of the armature 8 on the sleeve element 13 is sufficient to lift it out of the outer valve seat 12. Nevertheless, the sleeve element 13 is pulled out of the outer valve seat 12 if the pressure difference between the tank 14 and the anode channel 17 falls below a reasonable value, so that it is ensured that the large opening cross-section is opened reliably in these cases as well.
  • the opening is also supported by the fact that the pressure in the anode channel 17 increases continuously if the withdrawal of hydrogen from the anode channel 17 in the direction of the fuel cell is kept smaller than the supply of hydrogen from the tank 14.
  • the power supply to the magnet coil 9 is interrupted, so that no more magnetic force acts on the magnet armature 8.
  • This is pressed again in the direction of the inner valve seat 11 due to the spring 20.
  • the sleeve element 13 also moves in the direction of the outer valve seat 12, since the driver element 6 no longer rests on the sleeve element 13 and this no longer presses in the direction of the plate-shaped end 82 of the armature 8.
  • Both the outer valve seat 12 and the inner valve seat 11 are now blocked again, so that no gaseous medium can flow into the anode channel 17.

  • the second exemplary embodiment essentially corresponds to the first exemplary embodiment in terms of structure and function.
  • the driver element 6 is omitted here, the magnet armature 8 here having a shoulder in the sleeve interior 130 on which a spring 32 is supported and thus presses the magnet armature 8 in the direction of the inner valve seat 11.
  • the spring 20 and the recess 80 of the armature 8 are omitted in this exemplary embodiment.
  • an active function is achieved between the magnet armature 8 and the sleeve element 13 in that the spring 32 simultaneously pushes the magnet armature 8 in the direction of the inner valve seat 11 into a closed position and the sleeve element 13 by the spring 32 in the direction of the plate-shaped end 82 of the magnet armature 8 in force is applied to an open position.

From a certain point in time, due to the pressure conditions in the control chamber 30 and the sleeve interior 130 and the spring 32, the spring 4 is overpressed, so that the sleeve element 13 also lifts off the outer valve seat 12 and releases it. The spring 32 then serves as a driver for the sleeve element 13, which follows the movement of the magnet armature 8 and thus releases the large opening cross-section.
