A tube joint coupling consisting of a central, spherical, S-bent tube bend 3, and, on each side of this central tube bend 3, a two-dimensionally bent tube bend 4, 5 which is rotatably connected to the central tube bend 3, whereby the two outer tube bends 4, 5 are rotatable in each respective plane, orthogonal to each other. Sealing and guiding between the tube bends 3, 4 and 5, respectively, may be arranged outwardly, and the interconnection between the tube bends 3, 4 and 5, respectively, is adequately arranged inwardly and at least somewhat springy. Both outer tube bends 4, 5 may be formed with a bend of more than 90 degrees, and such that the outlets 8, 9 of the tube joint coupling extend essentially along the same axial line. <IMAGE> |
