1. A sealing device for sealing a cavity (40) that can be rotated around a rotational axis (A), comprising:
- at least two sealing areas separated from each other by at least one intermediate zone (Z1 to Z3);
two sealing faces (20, 21 to 24, 30, 31 to 33, 41, 71 to 74) continuously extending around the rotational axis and slidingly movable over each other upon rotation of the cavity (40), and at least one connection (A1 to A3, B1 to B3) for at least one of charging, discharging, and passing fluids into, out of, and through the at least one intermediate zone, respectively.
