Abstract
A radial rotary transfer assembly including at least one rotor (4) and at least one stationary part (1) The rotor (4) has at least two sealing surfaces (16, 18). Two sliding rings (2, 3) having at least two sealing surfaces (15, 17) are arranged between the stationary part and the rotor. The sealing surfaces (15, 17) of the sliding rings (2, 3) co-operate with the rotor sealing surfaces (16, 18), and with at least one radial through-flow duct (10) between the pairs (15, 16; 17, 18) of co-operating sealing surfaces. In order to structurally design a radial rotary transfer assembly in such a way that the installation thereof in matching centers and retro-fitment thereof on existing apparatuses is simplified and does not fail because of the small space available it is proposed in accordance with the invention that the normals (n16, n18) to the sealing surfaces of the rotor (4) face axially away from each other, wherein the normals (n15, n17) to the sealing surfaces of the sliding rings (2, 3) are directed axially towards each other.
