Abstract
The invention relates to a shut-off valve () for controlling a pressurized gas flow from a pressurized gas vessel () into a chamber () in a system, the shut-off valve () comprising a main valve (), a pilot valve (), a coil () and a tension spring (); when the coil is energized, it moves the pilot valve from a first pilot valve position into a second pilot valve position; in the first pilot valve position, the pilot valve gas-tightly seals a control channel () in the main valve between a control chamber () of the shut-off valve and the chamber () in the system, and in the second pilot valve position, the pilot valve opens the control channel; the tension spring mechanically couples the pilot valve to the main valve in order to move the main valve from a first main valve position into a second main valve position when the pilot valve moves into the second pilot valve position; in the first main valve position, the main valve gas-tightly seals a main channel () that connects the pressurized gas vessel to the chamber in the system, while in the second main valve position, the main valve opens the main channel ().
