摘要：
Disclosed is a metering device (1) which can be activated by the vacuum air stream of the user, for the inhalation of a metered dose of a powder substance (2), particularly medicine. The substance is arranged in a supply chamber (15) and can be brought out of the chamber into an open emptying-ready position (B) by means of a metering chamber (40) of a metering rod (33) when the mouthpiece-closure cap (7) is removed. In particular, the disclosure suggests, in order to improve dispensing, the provision of two air paths, of which one serves to open and empty the dosing chamber, and/or the second air path penetrates directly into a ring chamber (63) in order to mix with the air flow containing the substance.
