A flexible joint for transfer of especially a cryogenic fluid includes a first element (3) and a second element (4). The first element (3) comprising an internal, partly curved surface (6), the second element (4) comprising a corresponding outer partly curved surface (8) with at least a sealing element (12,12′) between the curved surfaces (6,8). The first element (3) comprises a first connection part (9) and the second element comprises a second connection part (10) connectable to the first connection part (9) with a flexible part (11, 11′) between the connection of the two connectable parts (9,10) and the sealing element (12). Thereby it is formed a void (16) which may be pressurized with an inert gas at a pressure equal to or higher than the pressure of the fluid to be transferred through the joint.

The invention claimed is: 1. Flexible joint for transfer of a fluid, for instance a cryogenic fluid, comprising a first element and a second element each able to be connected to respective fluid transfer elements, the first element comprising a first through going opening comprising an internal curved surface, the second element comprising a second through going opening and an outer curved surface corresponding to the internal curved surface of the first element and the first and second through going openings are in communication with each other, wherein: (a) the first element comprises a first connection part and the second element comprises a second connection part connected to the first connection part forming a sealed connection between the first connection part and the second connection part, (b) at least one of the first element or the second element comprises a flexible part, (c) at least one sealing element provided between the curved surfaces, (d) at least one sealing element provided between the first connection part and the second connection part forming the sealed connection, (e) a void between the sealed connection and the at least one sealing element provided between the curved surfaces, and (f) an inert gas, in the void, at a pressure equal to or higher than the pressure of the fluid to be transferred through the joint. 2. Flexible joint according to claim 1, wherein the curved surfaces are doubly curved or partly spherical. 3. Flexible joint according to claim 1, wherein the curved surfaces are partly spherical. 4. Flexible joint according to claim 1, wherein there are at least two sealing elements between the curved surfaces, and at least one sealing element between the connection parts. 5. Flexible joint according to claim 1, wherein there are at least two sealing elements between the curved surfaces. 6. Flexible joint according to claim 1, wherein there are at least two sealing members between the connection parts. 7. Flexible joint according to claim 1, wherein the connection parts are flanges. 8. Flexible joint according to claim 1, wherein the first connection parts is a first flange of the first element, the second connection part is a second flange attached to the second element through the flexible part. 9. Flexible joint according to claim 8, wherein the first flange is formed mainly outside the inner curved surface and the second flange is connected to the second element by a flexible element with a longitudinal axis mainly parallel with a longitudinal axis of the joint and a radially oriented fastening flange attached to the second element. 10. Flexible joint according to claim 9, wherein radially oriented fastening flange is positioned a distance from the outer curved surface of the second element.
