Swivel apparatus

A swivel apparatus for the transfer of at least one pressurized process fluid, comprising a central stem (2) on which there are arranged a number of ring elements (3-6) comprising at least two outlet rings (3) of which each has a number of outlets (10) communicating through an associated annulus (14) with an associated course (12 resp. 13) in the stem (2), and a number of supporting rings (5, 6) of which at least one is stationarily arranged on the stem (2), dynamic sealing means (21) for sealing against the annulus (14) being arranged between mutually movable ring elements (3, 5, resp. 3, 6), and bearing means (17) for mutual support of the ring elements, characterized in that, between the stem (2) and each outlet ring (3), there is arranged a distance ring (4) which is stationary relative to the stem, and that, on each side of each outlet ring (3), there is arranged a supporting ring (5 resp. 6) which is stationary relative to the stem (2) and so that each of the outlet rings (3) has its separate set of supporting rings (5, 6), wherein each of the supporting rings is supported both by the respective distance ring (4) and an axial bearing (17) arranged at a radial distance therefrom between the supporting ring (5 resp. 6) and the outlet ring (3) in question, a dynamic sealing means (21) between the individual outlet ring (3) and each adjacent supporting ring (5 resp. 6) being arranged in the region between the distance ring (4) and the axial bearing (17) in question.
