Abstract:
A swivel stack for transfer of fluid across a rotary interface around a main rotation axis between an incoming flow-line and an outgoing flow-line, includes an inner cylindrical body and a first cylindrical annular element. The cylindrical annular element is mounted on the inner cylindrical body so the rotational axes of the annular element and cylindrical body coincide. The inner cylindrical body has an internal conduit running from a cylindrical base parallel to the rotation axis. The conduit has an outlet port communicating with a circumferential cavity on the cylindrical surface of the inner cylindrical body. The first cylindrical annular element includes a toroidal cavity on its internal cylindrical surface. The first cylindrical annular element is mounted on the inner cylindrical body at the level of the outlet port so the toroidal cavity and the circumferential cavity form an annular chamber communicating with the outlet port of the internal conduit.

Claim (Index 1):
Swivel stack for transfer of fluid across a rotary interface around a main rotation axis between an incoming flow-line and an outgoing flow-line, the swivel stack comprising an inner cylindrical body and at least a first cylindrical annular element, the at least first cylindrical annular element mounted on the inner cylindrical body such that the rotation axis of the annular element and the rotation axis of the cylindrical body coincide;\n the inner cylindrical body having at least one internal conduit running from a cylindrical base of the inner cylindrical body parallel to the rotation axis of the inner cylindrical body; the at least one conduit having an outlet port in communication with a circumferential cavity on the cylindrical surface of the inner cylindrical body; the at least first cylindrical annular element comprising a toroidal cavity on its internal cylindrical surface; the at least first cylindrical annular element being mounted on the inner cylindrical body at the level of the outlet port of the conduit to provide that the toroidal cavity and the circumferential cavity form an annular chamber in fluid communication with the outlet port of the at least one internal conduit, and the cylindrical surface of the inner cylindrical body comprising a first circumferential groove below the level of the outlet port, in which a lower bushing is received, and a second circumferential groove above the level of the outlet port in which an upper bushing is received; the cylindrical annular element being rotatable around the inner cylindrical body while axially in locked position at the level of the outlet port of the conduit between the lower bushing and the upper bushing.
