The invention relates to dosing devices, namely to dosing devices for the inhalation of a powdery substance.The dosing device (1) for the inhalation of a powdery substance (2) can be activated by the vacuum air stream of the user. The powdery substance (2) is arranged in a supply chamber (15). The dosing device (1) can be brought out of the same into an open emptying-ready position (B) by means of a dosing chamber (40) of a dosing rod (33) when the closure cap of the mouthpiece (6) is removed. The dosing chamber (40) is sealed off with a piston (54). In the dosing device (1) are provided two air paths, of which one serves to open and empty the dosing chamber (40) by moving the piston (54) from the emptying-ready position and the second air path penetrates from the dosing chamber (40) directly into a ring chamber (63) arranged in front of the mouthpiece (6) in order to mix with the air flow containing the substance. |
