Device for filling a container with solid particles, the device including a diaphragm

A device for filling a container with solid. particles, the device comprising:

• annular ducts for passing particles in order to dispense particles uniformly in the container, the ducts being defined by a plurality of vertical nozzles arranged coaxially relative to one another;
• and
• a diaphragm arranged upstream from the annular ducts in order to regulate the flow of particles in the annular ducts;
• wherein the diaphragm has a plurality of shutter flaps for shutting off the annular ducts, each shutting off an angular sector of a single annular duct,
• wherein the diaphragm has control means for controlling the movement of the shutter flaps, and configured to enable any one duct to be shut off partially independently of the other ducts, and
• wherein each shutter flap is a flexible wall carried by two same-diameter annuluses mounted to pivot relative to each other, each flap being configured to shut off an angular sector of a single annular duct.
