Radial rotary transfer assembly

A radial rotary transfer assembly comprising:

• at least one stationary part (1);
• at least one rotor (4) comprising at least two sealing surfaces (16, 18) having normals (n16, n18);
• two sliding rings (2, 3) with overall at least two sealing surfaces (15, 17) having normals (n15, n17) arranged between the stationary part and the rotor, wherein the sealing surfaces (15, 17) of the sliding rings (2, 3) co-operate with the rotor sealing surfaces (16, 18) defining sliding ring seals;
• at least one radial through-flow duct (10) between the pairs (15, 16;
• 17, 18) of co-operating sealing surfaces, characterised in that the normals (n16, n18) to the sealing surfaces of the rotor (4) face axially away from each other and the normals (n15, n17) to the sealing surfaces of the sliding rings (2, 3) are directed axially towards each other, wherein the sliding ring seals are hydrostatically compensated within a range of from about 90% to about 100%;
• and
• wherein the stationary part (1) is of the cross-section of a U-shaped profile and forms an annularly peripherally extending clamp, wherein the limbs of the U-shaped profile axially embrace from the outside the sliding rings (2, 3) and the rotor (4).
