Abstract
The invention relates to a device (10) for providing an aerosol from an aerosolizable material, the device comprising an aerosolization unit (300) through which pressure pulses of a carrier gas (60) are passed; a reservoir (100) comprising the aerosolizable material and which provides the aerosolizable material to the aerosolization unit (300) where the aerosolizable material is entrained by the carrier gas (60); a material providing valve (210) located between the reservoir (100) and the aerosolization unit (300) which opens in direction of the aerosolization unit (300) and which is opened and closed by a pressure difference between the reservoir (100) and the aerosolization unit (300) and which provides, in an open state, the aerosolizable material to the aerosolization unit (300).
