A metering device can be activated by a suction airflow of a user for inhaling a powdery substance, in particular of medicinal type, which is arranged in a supply chamber and can be brought out of there into an apparent discharge standby position by removing a mouthpiece sealing cap by a metering chamber of a metering rod. A terminal frame is provided at the end plate in order to electrically connect an electrode terminal of the energy storage cell provided at an end in the stacking direction and an output line. The end piece is embodied so that before the tubing line is screwed down onto the fuel distributor line, it can be moved for tolerance compensation, in a seat on the inflow-side end of the fuel distributor line, in two directions perpendicular to the extent of the tubing line. Each of the shielding parts includes a wall portion facing upstream that is positioned such that the wall portion is struck by the purge air that passed through the passing hole of the neighboring upstream shielding part. Acronym assistance is provided for a reader and a writer using the text program. In at least some embodiments, a corresponding user interface can be created within an application such as, for example, a Web browser, to allow the user to specify locations at which they wish to see the site map.
