Abstract (en)
[origin: WO9007386A1] The device comprises a casing (1) provided with a barrel (2) passing through it, and with a powder accumulating-dosing arrangement (7). The device consists of three sections (3, 4, 5) of which the outer ones (3, 4) are rigidly connected to the casing (1), whereas the middle one (5) is provided with a drive for its reciprocal movement along the axis of the barrel (2). The lower part of the casing (1) located below the powder accumulating-dosing arrangement (7) constitutes a chamber (9) for the accumulation of the powder, provided with a mechanism (10) for returning the powder to the accumulating-dosing arrangement (7) located in one of the joining zones between the movable (5) and stationary sections (3, 4).
