  • Metering device for powdered material
    Patent number: 4703874
    Abstract: The metering device for powdered material comprises a storage container (10) for the powdered material and a discharge opening in the bottom of the storage container which is opened and closed, respectively, by a closing mechanism (12). The powdered material flows through the discharge opening into a drawing cup (13). In order to obtain a defined bulk density of the powdered material in the drawing cup (13), a vibration mechanism (14) imparts vibrations to the metering device when the discharge opening (11) is open. The closing mechanism (12) can be designed in the manner of a blade diaphragm, and in that case the closing mechanism (12) can be actuated by a grooved disk (17) which at the same time is a part of the vibration mechanism (14).
