The rotating transfer face of the rotary passage (1) is associated with a medium transfer pipe which is set with radial play coaxial with the tension rod (2) of the turning machine part (3) and overlaps this in the axial direction by a greater amount than the maximum axial displacement during use of the rod relative to the co-rotating medium transfer pipe. The radially outer pipe element has an axially aligned fluid transfer channel (4) and the inner pipe element is closed at its end (5) projecting into the outer element. Two seals (6,7) are provided in the overlapping area between the tension rod and pipe section axially spaced from each other. |
