ABSTRACT:
The invention relates to rotating machine element that contains a mechanism actuated by a fluid pressure. The aim of the invention is to allow for a supply of actuation fluid also during the rotation. To this end, a non-rotating control element (2) is mounted on two fluid bearings (3) on the machine element, said bearings being spaced apart in the axial direction and allowing flows of actuation fluid to flow from one element to the other. Feed lines (R, S) in the control element are provided with a series of radially inwards facing ports (13, 14) and reception channels (17, 18) in the machine element, a series of radially outward facing orifices (15, 16) being disposed in such a manner that in every relative position both elements for every individual flow of actuation fluid are disposed such that at least one port (13, 14) is aligned with one associated orifice (15, 16).
