several independently rotatable against each other. Such a solution is realized in a known front ring disks (2, 2 ft; 13 a, 13 δ; 14 α, 14 ft) device, in which when the rotated the rotated are seen that either center around one another Part a corresponding length of the energy giant or are arranged axially next to each other, supply line drawn and with the opposite, in the latter case each is withdrawn again in the direction of rotation. Such ring disc arrangement devices closest to the point of departure are expensive, especially then, voltage (14 a, 14 ft) compared to an annular disc arrangement (13 α, 13 ft) proceeding from a central position when the rotatable part moves in both directions to rotate more than rotatably connected cylindrical ring (17) 180 °, is rotatable. Furthermore, a cable guide is known in which

Is stretchable in the longitudinal direction. This cable routing is hoses was previously only thinly applicable under such conditions, if the fixed point was only possible in an extremely complex way,
