Abstract
A cryogenic reservoir (1) comprising an internal reservoir (2) and an external reservoir (5) with vacuum insulation between them, is provided with a plug-valve (17) in a conduit (12) passing through the external reservoir (5). This plug valve (17) incorporates the trapping agent of the desorption gases, as a getter. In the case of accidental overpressure in the intermediate vacuum space, due to an escape of fluid from the internal reservoir (2), the 'getter' is ejected to a distance with the plug valve (17), which avoids any dangerous reaction between the getter and the cryogenic fluid, which can for example be oxygen.
