Abstract
The invention relates to a tank device () for storing a gaseous medium, in particular hydrogen, comprising a valve device () and a tank container (), wherein the valve device () comprises a valve housing (), in which valve housing () a pilot valve element () that can be moved along a longitudinal axis () of the tank container () is disposed. The pilot valve element () cooperates with a first sealing seat () to open and close a passage opening () and thus forms a pilot valve (), wherein the valve device () comprises a solenoid coil () by means of which solenoid coil () the pilot valve element () can be moved along the longitudinal axis () of the tank device (). A main valve element () is furthermore disposed in the valve housing (), which main valve element () cooperates with a second sealing seat () to open and close a passage opening () and thus forms a main valve (), wherein the second sealing seat () is configured as a conical shoulder () on the valve housing (). In addition, a permanent magnet () is disposed at one end () of the pilot valve element (), which permanent magnet () is disposed in the valve device () such that a positive pole element () of the permanent magnet () is disposed in the direction of a housing cover () of the valve device () and a negative pole element () of the permanent magnet () is disposed in the direction of the tank container (), wherein the permanent magnet () is disposed in a positive pole region () of a permanent magnetic field () generated by the solenoid coil () when the solenoid coil () is energized.
