5. The device according to claim 3 , characterized in that a spring is mounted around the at least one control rod such that the at least one control rod is compressed when the at least one movable annular support is brought closer to the at least one fixed annular support.

6. The device according to claim 1 , characterized in that the device further comprises means for controlling the relative displacement of a plurality of movable annular supports to adjust the distance separating them.

7. A device for loading solid particles into a vessel, comprising:

a means for supplying solid particles to be distributed, arranged on an upper part of a vessel to be loaded;

a supply pipe comprising at least one orifice for discharging the solid particles which is arranged on a side and/or horizontal wall, such that the means for supplying solid particles pours the solid particles substantially vertically into the supply pipe;

a movable assembly arranged below the supply pipe entirely or partly inside the vessel, comprising:

a driving means;

a substantially vertical central shaft driven in rotation by the driving means, the substantially vertical shaft being surrounded at least partially by the supply pipe; at least one movable annular support which supports a plurality of deflector elements, the at least one movable annular support being mounted in sliding fashion on the central shaft;

wherein the plurality of deflector elements are integral in rotation with the shaft, arranged around the shaft on at least one of a plurality of vertical tiers, and articulated in such a way that the plurality of deflector elements can lift up under the effect of the rotation of the movable assembly, and

the device further comprises at least one lever which exerts pressure on the at least one movable annular support, the lever comprising a vertical part that slides parallel to the central shaft and is articulated with an actuating arm, a free end of the vertical part bearing against an upper face of the at least one movable annular support.
