发明名称 Toroidal fluid swivel for transfer of fluid across a rotary interface
摘要 A swivel for transfer of fluid across a rotary interface around a swivel rotation axis between an incoming fluid line and an outgoing product piping includes a fixed annular element and a rotating annular element, each arranged around a common rotation axis and having a substantially equal diameter. One selected element from the fixed annular and rotating annular elements includes an annular disk provided with a toroidal cavity in a first of its circular end surfaces, and the other selected element is arranged with a flat circular end surface adjacent to and in close proximity above the first circular end surface to close the toroidal cavity and form a toroidal chamber with the annular disk. The rotary interface is perpendicular to the rotation axis, and is formed by the flat circular end surface of the other selected element and the adjacent first circular surface of the one selected element.
