Abstract (en)
[origin: EP2166259A1] The device has a sliding surface arranged on a front side (51) of a pre-stressed sealing ring (5) i.e. shaft seal, and another sliding surface arranged on an edge (21) of a groove (22). Another edge (23) of the groove has a circular recess (26) guided around an axis of rotation, such that the recess is limited radially outward by a circular body (24) molded into a rotor (R). The body forms a section of an outer surface of the rotor and has a circular edge (25) attached at the outer surface. The circular edge reduces the size of a grinding surface, during butting of the ring at the edge (23). An independent claim is also included for an exhaust turbo charger comprising a turbine.
