Abstract

The invention concerns a rotating machine such as a carrousel comprising a rotating frame driven in rotation about an axis of rotation, several working stations supported by the rotating frame, a fluid supplying rotating column, coaxial to the axis of rotation of the rotating frame. The invention is characterized in that it comprises a column element (50, 250) provided with two assemblies (52, 252, 53) mobile in rotation relative to each other, about said axis of rotation, a first assembly (52, 252) including an axial tubular body (80, 280) provided with at least two tiers of radial through holes (81-86, 281-286), the axial conduits of the first assembly (52, 252) extending over different lengths in the space delimited by said tubular body (80, 280), each conduit (65a, 70-73, 75) emerging perpendicularly to one specific tier of radial through holes (81-86, 281-286), the column element (50, 250) thereby defining a rotating connection dispensing at least two fluids towards the working stations of the machine, and in that a sleeve C is interposed between said tubular body (80, 280) of the second assembly (53) and said first assembly (52, 252).
