ABSTRACT:
This invention is directed to a novel rotary joint or coupling which is useful for coupling a rotating element to a non-rotating element. More particularly, this invention is directed to a novel rotary joint or coupling which couples a rotating element to a non-rotating element and allows for the passage of a process fluid from the rotating element to the non-rotating element or vice versa, and seals the flowing process fluid from the external environment. A rotary joint useful for connecting a stationary object to a rotating object comprising: (a) bearing housing adapted to be joined to either the rotating or the stationary object; (b) fluid conveying conduit adapted to be joined to either the stationary or rotating object to which the bearing housing is not joined; (c) sealing member positioned between the fluid conveying conduit and the bearing housing for preventing migration of fluid from the fluid conveying conduit into the bearing housing; and (d) rotatable bearing positioned between the bearing housing and the fluid conveying conduit and exterior to the sealing member, said rotatable bearing being lubricated and cooled by a lubricating substance.
