The turbine () has a rotor () with blades () arranged on a periphery of disks () in radial planes (), and a tie rod () extending along slots () in the disks. An annular spacer (') fixes a position of the tie rod relative to a center line (M) of the disks, and is arranged in a channel (). The spacer has through-openings, which are arranged radially relative to the tie rod or to its center line, and extend coaxially. The channel carries a cooling medium and is limited by a separating pipe () radially outwards. The through-openings serve for flow of the medium.
