The invention relates to an inhalator (1) for powdery substances (33), especially medical substances. Said inhalator comprises a substance reservoir chamber (27) and a metering chamber (34) receiving a defined amount of the substance. The metering chamber is configured as a crossbore (35) of a rod (36) and can be displaced from a filling position (B) to a discharge position (E), in which discharge position (E) the metering chamber (34) is positioned in an air flow channel (21). The aim of the invention is to provide an inhalator of the aforementioned type which allows the metering chamber to be emptied in a manner that is optimal for the patient. For this purpose, the rod (36) has a plurality of metering chambers (34), arranged one behind the after on the rod (36). Said chambers reach the discharge position (E), preferably one by one, during a discharge actuation, and can be blown out one by one as intermingling small portions (instead of one large one) by the effect of the positive air pressure in the air flow channel (21). |
