A powder metering apparatus (1) comprising a metering chamber (2) which defines a powder metering volume (3) and can be emptied through an outlet opening (11), wherein, in order to draw in powder (9) from a powder supply line (10) through a diaphragm (5) which bounds the metering chamber (2), a negative pressure (8) can be applied to the metering chamber (2). The diaphragm (5) is arranged such that the latter can be adjusted relative to the outlet opening (11) in order to set the powder metering volume (3) and/or to empty the metering chamber (2). |
