Abstract
A tank device for storing a gaseous medium includes a valve device and a tank, the valve device includes a valve housing with a pilot valve element movable by a solenoid coil. The pilot valve element interacts with a first seal seat. A main valve element is arranged in the valve housing and, in order to open and close a through-opening, interacts with a second seal seat formed as a conical shoulder on the valve housing. A throttle channel is formed between the valve housing and an integrally molded shaping of the main valve element, which integrally molded shaping interacts with a second seal seat to open and close the through-opening, and said throttle channel has a conical widening against a direction of the second seal seat, whereby a throttle effect is provided, the valve device being openable in a direction of the tank when the solenoid coil is energized.
