description	In order to secure the outer vessel (2) of double-walled vacuum-insulated storage tanks for low boiling liquefied gases against an increase in pressure in the insulation space in the event of failure of the vacuum, valves are used which consist of a valve housing (1), mounted in the outer vessel, a sealing plug (3) and an O-ring (4), as the sealing element. The O-ring is deformed exclusively in the axial direction by the pressure difference between the atmosphere and the vacuum and an additional spring force. This valve is little suited to small vessels, inter alia because of the relatively large structural volume resulting from the spring. In a valve which is particularly suitable for small vessels, the O ring is thus deformed radially and, at the same time, axially, exclusively under the influence of the external air pressure, as a consequence of the dimensions of the valve housing and the sealing plug.
