摘要
The rotating connection comprises a cryogenic of the sections (11, 16) of the cryogenic line may have between them a rotational movement about an axis of rotation (1) of the rotating connection. The elements (13) for retention in the radial direction and the elements (19; 40) for retention in the axial direction of which define the axis of rotation (1) of the rotating connection. The section (11) comprises a female part (10) with a double wall insulated under vacuum and the other portion (16) comprises a male part (15) with a double wall insulated under vacuum at least partially engaged in the female part (10). A first sealing ring (12) is interposed between a free end (15a) of the male part (15) is engaged in the female part (10) and (19 a, 40) of the retaining elements. A second seal (14) is interposed between a free end (10a) of the female part (10) surrounding the male part (15) and the other (13) of the retaining elements. A heating device (17) is arranged in the vicinity of the second seal (14).
