A novel rotary joint (2) or coupling which couples a rotating element (6) to a non-rotating element (7) and allows for the passage of a process fluid (24) from the rotating element (6) to the non-rotating element (7) or vice versa, and seals the flowing process fluid (24) from the external environment. A rotary joint (2) useful for connecting a stationary object (7) to a rotating object (6) comprising: (a) bearing housing means (4) adapted to be joined to either the rotating (6) or the stationary object (7); (b) fluid conveying means (5) (14) adapted to be joined to either the stationary (7) or rotating object (6) to which the bearing housing means (4) is not joined; (c) sealing means (16) (18) positioned between the fluid conveying means (5) (14) and the bearing housing means (4) for preventing migration of fluid (24) from the fluid conveying means (5) (14) into the bearing housing means (4); and (d) rotatable bearing means (9) (10) positioned between the bearing housing means (4) and the fluid conveying means (5) (14), and exterior to the sealing means (16) (18), said bearing means (9) (10) being lubricated and cooled by a lubricating means (32) (34). |
