Connection system for a cryogenic tank

Abstract

A connection system for a cryogenic tank with a tank wall formed with a first material. A connector is provided for a component to be connected to the tank. The connector is formed with a second material, and the connector is positioned on an exterior side of the tank and essentially congruent with a passage opening of the tank wall. At least one sealing element is provided, and the first and the second material have different thermal expansion coefficients. A counterpart formed with the second material is positioned on an interior side of the tank, and is connected with the connector via at least two fastening elements, such that the tank wall is clamped between the counterpart, the connector and the at least one sealing element, and a slight displaceability of the connector and the counterpart parallel to the tank wall remains to compensate for thermally induced mechanical stresses.

Dependencies are inferred from the claim text.
