In an inhalation system (1) for inhalation of a dosing aerosol (6′), comprising:a dosing device (6) which delivers the aerosol (6′)a container (2) in which one or more chambers (4, 5) separated from one another and connected together during inhalation by means of one or more valves (8) are provided,with an inlet opening (7) emerging into the first chamber (4), into which opening the dosing device (6) is inserted,with the second chamber (5) having a first passage opening (9) which interacts with the respiratory openings of a human being (20),with the second chamber (5) having a second passage opening (10) that is connected to the surrounding air (15) and through which a positive pressure in the second chamber (5) can escape into the surrounding air (15) during exhalation, a simple and hygienic application of the inhalation arrangement (1) should be guaranteed and the aerosol flow should have a linear and rotating motion induced in it during the inhalation procedure.This is achieved in thatthe valve (8) is formed from an elastically deformable material, preferably silicone, that the valve (8) has a ring-shaped circumferential collar (21) that is fixed to the container (2),at least one slot-shaped notch (22) is worked into the valve (8) which is configured as a spiral running from inside to outside,that during inhalation, the valve (8) acts as a barrier to the flow of the aerosol (6′) flowing through it, as a result of which a linear motion and a spiral-shaped flow direction (11) along and about the longitudinal axis (3) of the container (2) is imposed on the aerosol (6′), channelling it into a three-dimensional spiral
