A plurality of rings (124) are provided on an interior side of the section of the cylindrical body, aligned with the shoulders to thereby create a like plurality of annular slots (128). A plurality of cooling holes (130) are formed in section of the cylindrical body, radially overlying the rings, and adapted to supply cooling air to the annular slots. A plurality of flow disseminators (32) are provided on a radially outer side of the rings (124), aligned with the cooling holes (130), and configured to spread the cooling air flowing through the cooling holes (130).
