Abstract

The invention relates to a device for discharging a powder in a quantised manner, having a metering element (3) that comprises first metering recesses (6) and can be driven rotatably about a rotational axis (4) in a housing (1), and a filling volume (14) in which said metering recesses (6) can be filled with the powder, wherein means (19) are provided, at an emptying point (11), for generating a fluid stream by means of which the powder can be conveyed out from the first metering recesses (6) into an outlet volume (13). The first metering recesses (6) are open toward an edge (3') of said metering element (3). The metering element (3) is surrounded by an annular element (5) which has second metering recesses (7) that are open in the radial inward direction, said annular element (5) being fixedly associated with the housing (1).
