ABSTRACT:
A device for the transfer of a cryogenic medium between a fixed and a rotating conducting tube with a sealing device having a corotating sealing element to seal off an annular space between a fixed and a rotating section of conducting tube, in which the sealing device is disposed in the space with its radially oriented sealing element, which is fastened to the outside of the rotating section of tube, made sufficiently elastic that its radial dimension when rotating is increased by a predetermined amount to permit shrinkage differences occurring upon cooling to be equalized to a large extent so that a good seat is obtained.
