17 Claims

1. A tank device (1) for storing a gaseous medium, comprising a valve device (2), and a tank (10), and having a longitudinal axis (11), wherein the valve device (2) has a valve housing (20), wherein the valve housing (20) is equipped with a pilot valve element (18) that can be moved along the longitudinal axis (11), the pilot valve element (18) interacting with a first valve seat (27) to open and close a first outlet opening (56) and thus forming a pilot valve (44), wherein the valve device (2) can be controlled by a solenoid coil (14), wherein a main valve element (19) is arranged in the valve housing (20) in a direction coaxial to the pilot valve element (18), said main valve element (19) interacting with a second valve seat (40) to open and close a second outlet opening (31) and thus forming a main valve (191), wherein the tank device (1) comprises a screw-in housing element (24), wherein the valve device (2) is coupled to a neck region (6) of the tank (10) in a fixed manner by the screw-in housing element (24), and wherein the valve device (2) is arranged outside the tank (10) and is axially spaced from the neck region (6) and is in a closed position when the solenoid coil (14) is deactivated.
