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 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).
