The system has sealing elements (22), whose sectored annular assemblies (20a, 20b) are connected to an inner shaft (12) and mobile under an effect of a centrifugal force, where the assemblies are radially displaceable towards an outer shaft (14). An annular receptacle i.e. annular groove (42), for liquid i.e. oil, is arranged at an inner surface of the outer shaft relative to curved edges of the sealing elements. The curved edges are immersed into the oil when the sealing elements are displaced under the effect of centrifugal force. |
