A cryogenic tank (1) comprising an internal tank (2) and an external tank (5) with insulating vacuum between them is equipped with a valve plug (17) in a duct (12) passing through the external tank (5). ). This valve plug (17) incorporates the desorption gas trapping agent, such as a getter, so that in the event of accidental overpressure in the interstitial space under vacuum, due to a leak from the internal reservoir (2), the "getter" is ejected remotely with the stopper-valve (17), which prevents any dangerous reaction between the getter and the cryogenic fluid, which can be for example oxygen. |
