The invention relates to a spray-diffuser for the atomization of liquids or solid substances, such as medicaments, with the help for the flow of compressed air, particularly for inhalation purposes. The spray-diffuser comprises a spray-diffuser nozzle (3) located in an atomizing chamber (10), which nozzle is connected to a compressed air channel (2) and comprises a suction device for sucking up the medicament, wherein the compressed air channel adjacent the nozzle has a release opening (15) for escape of the compressed air, which opening is settable to a non-operation position, and which can for example be closed during inhalation of the patient and opened during exhalation of the patient. In known spray-diffusers, diverted air is guided through the release opening with a development of a hissing noise and a danger of harm to the staff. In order to avoid this disadvantage, in the spray-diffuser according to the invention the release opening leads into the atomizing chamber. Expediently, the release opening is positioned on that side of the compressed air channel which is averted from the supply chambers 7 for the substance to be atomized.
