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.
