Abstract
A sealing arrangement for the sealing-off of metallic cylindrical bodies is disclosed, particularly for shafts in cryogenic valves which are surrounded by an essentially ring-shaped sealing device which cannot be glued to metal. The sealing device is surrounded by a ring which is arranged concentrically with respect to the shaft, consists of a metal alloy with shape memory characteristics and with a one-way characteristic and the interior shape of which is adapted to the exterior shape of the sealing device and which contracts when the transition temperature is exceeded.
