Abstract:
A split ring for mounting with elastic prestress in an annular groove of a rotary part of a turbomachine and having, in the free state, a diameter that is greater than the diameter of the groove, is remarkable in that, in the free state and without stress, the end portions of the ring are circular arcs having a radius of curvature that is substantially equal to the radius of curvature of the annular groove.
