<p>The invention relates to an atomizer for distributing liquids from at least one cartridge inserted in the atomizer and to a cartridge and to a system comprising an atomizer and a cartridge inserted therein. Atomizers (1) of the aforementioned kind are for example required for the application of inhalable liquid pharmaceutical formulations and comprise, as the essential structural components, a cartridge holder (4), arranged in the housing (3), a mouthpiece (5) configured on the housing (4), in which an atomizer device (6) is located, and a connecting pipe system (7) which interlinks the atomizer device (6) and the cartridge holder (4). The atomizer device (6) comprises at least one nozzle base (8) and the connecting pipe system (7) comprises at least one channel (9) with a tubular piston (10) slidably guided therein, whereby said tubular piston (10) comprises a valve base (21). According to a first embodiment, the atomizer (1) is provided with a first tubular piston (10a), slidably guided in a first channel (9a), and a second tubular piston (10b), slidably guided in a second channel (9b), and the first tubular piston (10a) and the second tubular piston (10b) extend into the cartridge holder (4).</p> |
