  • Patent number: 8763653
    Abstract: The invention relates to a filling assembly for volumetric metering of fine grained powder (2) and to a method for operating said filling assembly. The powder (2) is provided in a resting state in the storage container (15) arranged on the inlet side of a filling line (8), and in the filling line (8) itself. The filling device (1) has a cover (7), a filling line (8) led through the cover (7) and pressure line (9), and also a pressure pulsation device (10). A metering container (3) is moved with its filling opening (5) under the cover (7) of the filling device (1) in such a way that the filling line (8) and the pressure line (9) open into the interior (4) of the metering container (3). By means of the pressure pulsation device (10), a pressure (p) oscillating about the atmospheric ambient pressure (po) as an average is generated and, by means of the pressure line (9), is transmitted into the interior (4) of the metering container (3).
