Lubricating liquid manifold for a crankpin of an epicyclic gear train, gearbox and aircraft

A lubricating liquid manifold for a crankpin, the crankpin being configured to carry a rotational guide device, the manifold being configured to receive a first flow and a second flow of a lubricating liquid, the first flow and the second flow being separate,

• wherein the manifold comprises:
• a hollow body around a geometric axis and provided with:
• an inlet port configured to receive the first flow of the lubricating liquid;
• and
• an outlet port configured such that the first flow is conveyed towards the guide device connected to the crankpin,
• a barrier configured to divert the second flow of the lubricating liquid, the barrier comprising:
• a shoulder connected to the body and provided with a bearing face, the bearing face extending in a bearing plane;
• a deflector situated on an opposite side to the outlet port in relation to the bearing plane, the deflector protruding radially outwards from the body, locally, moving away from the geometric axis;
• and
• a diversion space for diverting the second flow situated between the deflector and the bearing plane.
