The present invention relates to a cryogenic vessel (300a, 300b) having an inner container (301), an outer container (302), an intermediate space (303) between the inner container (301) and the outer container (302) which can be evacuated, and having at least one fluid distribution container (200), which has an internal volume which extends proceeding from one wall of the inner container (301) into the intermediate space (303), is arranged at least partially within the intermediate space (303) and is fluidically connected to the inner container (301), wherein the internal volume of the fluid distribution container (200) is delimited by a wall which has openings (211, 212, 213) that are designed for the connection of one line (311, 312, 313) each or are each connected with one such line (311, 312, 313). The wall (121, 221) has a convex section (101, 201), wherein a wall thickness of the wall at at least one point is less than 90% of a wall thickness of the inner container (301). The invention also relates to a fluid distribution container (100, 200) and to a method for producing a cryogenic vessel (300a, 300b).

The invention relates to a tank wall (1) fixed onto a supporting wall (3) wherein the secondary insulating barrier comprises a plurality of secondary rows (A, B, C) parallel to a first direction and juxtaposed in a second direction at right angles to the first direction according to a repeated pattern. The secondary sealed membrane comprises a plurality of strakes (21) parallel to the first direction, the size of the repeated pattern of the secondary rows (A, B, C) being an integer multiple of the size of a strake (21) in the second direction. The primary insulating barrier (5) comprises a plurality of primary rows parallel to the first direction, and the primary sealed membrane has first corrugations (56) parallel to the first direction and spaced apart by a first regular spacing (58), wherein the size of the repeated pattern of the primary rows is an integer multiple of said first regular spacing (58).

A dual-wall, vacuum-insulated container (30, 40) has an external wall (1), an internal wall (3) and there in-between a vacuum chamber (5), in which there is arranged a heat insulation device (2, 20). At least three temperature sensors (13, 13a, 13b, 14, 15) that are spaced apart from another recurringly register instantaneous temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) of the container (30, 40). At least in some points there is calculated a temperature course using a heat insulation model on the basis of the construction and material characteristics of the container and the heat radiation resulting therefrom, which temperature course contains at least two of the temperatures (T.sub.1, T.sub.2, T.sub.2A, T.sub.2B, T.sub.3) registered. From the temperature course there is calculated a desired temperature value for the position of at least one further of the temperature sensors and compared with the actual temperature value actually registered by this temperature sensor. From the deviation between the desired temperature value and the actual temperature value there is detected a change of the heat insulation quality of the container.

A tank suitable for storing a product at a cryogenic temperature, including a fluid tight interior barrier, a fluid tight exterior barrier, surrounding the first interior barrier, an intermediary volume interposed between the interior and exterior barriers and at least one insulating layer positioned in the intermediary volume and including at least one thermal insulation mat, with very low thermal conductivity. The intermediary volume contains microspheres outside of the thermal insulation mats and has an enhanced level of vacuum. This solution makes it possible to maintain satisfactory performance in terms of thermal insulation even in the event of a loss of vacuum in the intermediary volume.

A pressure vessel, in particular a cryogenic pressure vessel, has an inner vessel, an outer vessel and a chamber that can be evacuated at least partly. A motor vehicle includes such a pressure vessel.

A closing element for selectively blocking an opening of a cryogenic storage container is disclosed. The closing element has a head assembly and a bottom member, at least one layer of insulating material disposed between the head assembly and the bottom member, at least one hole extending through the insulating material, and at least one member disposed in the at least one hole and extending through the insulating material. A diameter of the at least one hole is substantially equal to a diameter of the at least one member.
