Abstract (en)

[origin: WO2022100974A1] The invention relates to a tank device (1) for storing a gaseous medium, in particular hydrogen, comprising a valve device (2) and a tank (10) and having a longitudinal axis (11). The valve device (2) has a valve housing (20) which is equipped with a pilot valve element (18) that can be moved along the longitudinal axis (11), said pilot valve element (18) interacting with a first valve seat (27) in order to open and close a first outlet opening (56) and thus forming a pilot valve (44). The valve device (2) can be actuated by means of a solenoid coil (14), and a main valve element (19) is arranged in the valve housing (20), said main valve element (19) interacting with a second valve seat (40) in order to open and close a second outlet opening (31) and thus forming a main valve (191). The tank device (1) comprises a screw-in housing element (24), wherein the valve device (2) is integrated into a neck region (6) of the tank (10) in a fixed manner by means of the screw-in housing element (24), and the valve device (2) is arranged in the tank (10) by means of a tank pressure and is in a closed position by means of a spring (26) when the solenoid coil (14) is deactivated.
