The invention relates to a device for filling a chamber with a divided solid comprising a divided solid feeder hopper (1), an exhaust chimney (2) fixed to said hopper or connected thereto by a supply conduit (3), a motor unit (4) rotatably driving a shaft (5) which is substantially disposed in the direction of the exhaust chimney and at least one deflector member (8) which is mounted downstream of the output orifice(s) (6, 7) of the exhaust chimney and is pivotable about sail shaft (5) in such a way that it angularly moves away therefrom due to a centrifugal force when said shaft (5) rotates. The shaft (5) is embodied in such a way that it is hollow and shaped in the form of a tube whose internal diameter is sufficient for passing a functional device (9) therethrough.
