摘要

The device for purposes of an inhalation therapy comprises an air inlet duct (1c) which includes an end section (1d) limiting the motion of the valve element (13) in such a way that the air inlet holes (12) are opened only to a threshold value which is proportional to the reduced pressure in the aerosol space of the device.
