Tank device for storing a gaseous medium, comprising a valve device

A tank device (1) for storing a gaseous medium comprising a valve device (100) and a tank (200), wherein the valve device (100) comprises a valve housing (102), in which valve housing (102) a pilot valve element (24), which can be moved along a longitudinal axis (48) of the tank device (100), is arranged, which pilot valve element (24) interacts with a first seal seat (18) for opening and closing a first through-opening (20) and thus forms a pilot valve (240), wherein the valve device (100) comprises a solenoid coil (32) operable to move the pilot valve element (24) along the longitudinal axis (48), wherein a main valve element (12) is arranged in the valve housing (102), which main valve element (12) interacts with a second seal seat (6) for opening and closing a second through-opening (8) and thus forms a main valve (120), wherein the second seal seat (6) is configured as a conical protrusion (36) on the valve housing (102), wherein the pilot valve element (24) has a transverse bore (241) perpendicular to the longitudinal axis (48) of the tank device (1), said transverse bore (241) of the pilot valve element (24) opening into a transverse bore (121) of the main valve element (12) arranged perpendicularly to the longitudinal axis (48) of the tank device (1), wherein a driver element (66) is at least partly arranged in the transverse bore (241) of the pilot valve element (24) and in the transverse bore (121) of the main valve element, wherein the main valve element (12) is subjected to a force in a direction of a tank interior (201) by a spring (22), as a result of which the main valve element (12) is subjected to a force in a direction of the first seal seat (18) and counter to a direction of the second seal seat (6).
