Each annular channel provides a fluid flow path for a corresponding radial channel in the central core, and a device for sealing the annular channel or each annular channel to prevent leakage of high-pressure production fluid. The sealing device includes a seal driven by differential pressure and a mechanism for supplying a barrier fluid to the side of the seal, The barrier fluid supply mechanism is away from the flow of the production fluid.
