    Abstract: A wheel rim that includes a peripheral structure for receiving a tire, and a central structure for coupling with a hub of the vehicle. The peripheral structure includes, for each side of the wheel rim, a peripheral flange, a connecting wall on which the bead of the tire rests, and a connecting part. The peripheral structure includes a central well. The connecting part includes a first curved region which joins the central well, and a second curved region between the first curved region and the connecting wall. The second curved region has a convex profile from the side of the wheel rim with the tire, and includes a first curved surface joined to the connecting wall with a first radius of curvature, and a second curved surface between the first curved surface and the first curved region, with a second radius of curvature different from the first radius of curvature.

    Abstract: A rotary feed-through, designed to transfer a fluid between two entities in rotary motion with respect to one another. The rotary feed-through includes an inner cylindrical ring and an outer cylindrical ring, which are free to turn with respect to one another and provided with channels for passage of the fluid. The channels are connected via at least one annular space axially delimited by seal rings housed in a cylindrical seat. The cylindrical seat faces radially outwards or inwards and is axially delimited, on one side, by an axial abutment of the inner and outer cylindrical rings and, on the other side, by an axial abutment of a lid, a closing ring, or an intermediate ring. The seal rings are interference fitted to the inner or outer cylindrical ring and provided with an elastic portion for contact with the surface of the inner or outer cylindrical ring.
