Abstract
A charging device is provided for feeding an enclosure with a predetermined flow rate of a solid material. The device comprises a materials hopper, a pipe for feeding the enclosure, and a member for retaining and for regulating the flow rate of material. The member for retaining and for regulating the flow rate of material comprises a bell for closing off a discharge opening, and a central metering body which is oblong and distinctly more slender than the bell. The bell and the central metering body can be moved relative to one another so that the distance which separates the two of them can be freely adjusted.
