Abstract
A swivel for use in a rotator is disclosed. The swivel includes an inner member having a cylindrical portion and an annular outer member arranged around the inner member and rotatably connected thereto via a bearing. At least one of the inner member and the outer member is provided with an annular fluid channel, one of the members having a fastening flange with an upper and a lower flange surface. The flange includes attachment structure configured to fix the flange to a support structure. A first fluid path extends through the flange from a first opening in a circumferential face of the fastening flange, to the fluid channel. A second fluid path at least partially extends through the inner member in a substantially axial direction from the fluid channel to a second opening.
