Abstract: Fluid delivery device, allowing a mechanical robot arm to be supplied with fluids from at least two sources of fluids, includes a fixed portion or stator, having connections to the sources of fluids, and a rotating portion or rotor, capable of moving with the robot arm, and comprising a plurality of connections for a link with the said robot arm. A first series of channels run through a central portion of the rotor sealing at a passage between the rotor and the stator is provided by seals. A second series of channels run through a peripheral portion of the rotor. Continuity between portions of these channels situated respectively on the rotor and the stator is provided in a zone without contact, with a reduced mechanical clearance.
