Tank device with 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 (101) of the valve 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 (101), 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 shoulder (36) on the valve housing (102), wherein between the valve housing (102) and an integrally molded shaping (37) of the main valve element (12), which integrally molded shaping (37) interacts with the second seal seat (6) to open and close the second through-opening (8), a throttle channel (38) is formed, which throttle channel (38) comprises a conical widening towards the second through-opening (8), as a result of which a throttling effect is formed, wherein the valve device (100) can be opened in a direction of the tank (200) when the solenoid coil (32) is energized, and wherein the valve device (100) is arranged in a neck region (203) of the tank device (1) and is pressed against a tank floor (140) within the neck region (203).
