摘要：
A device for the transfer of high frequency electrical signals between a rotating component and a stationary component, in particular for use in a CT system, in particular in a gantry of a CT system has a rotor, a stator; at least one brush attached at the stator, with a number of electrically conductive fibers that establish sliding contact with the rotor, and a slideway arranged to the side of the rotor and facing toward the stator. The fibers of the at least one stator-side brush rest on the slideway. A lubricant is provided on the slideway, a rotor has a capture device for the lubricant that is arranged around the outside of the slideway, and at least one return element for the captured lubricant is attached at the stator.
