Rotary feed-through with a sliding segment

The annular rotary feed-through structure has a stator (3) which is rotatably supported with respect to a stator ring (2). The annular duct (9) having U-shaped cross-section is provided with an annular opening. Both sides of the annular opening are sealed by sealing elements (12,13). The annular seals (19,20) are provided at two ends of the sliding segment (21). The sliding segment is provided with a radial hole (24) for connecting the vehicle-side terminal (25) of the stator ring and wheel-side terminal (26) of the stator.
