Abstract:
1. A device for transferring high frequency electrical signals between a rotating component and a stationary component, comprising: a stator; a rotor that rotates relative to said stator; at least one brush attached to said stator, comprising a plurality of electrically conductive fibers that establish a sliding electrical contact with the rotor; a slideway mounted at a side of the rotor facing toward the stator, said brush being attached to said stator with the fibers thereof resting on the slideway; a lubricant located in the slideway; a capture device at the rotor configured to capture lubricant at a location in the slideway to which the lubricant is moved by centrifugal force occurring upon rotation of said stator; and at least one return element in fluid communication with said capture device that returns lubricant captured by the capture device to the slideway, said return element being attached at the stator.
