Abstract:
1. Aerosol generator in particular for therapeutic aerosols with an oscillating membrane to one side of which a liquid may be fed and which may be brought to oscillation in order to transport the liquid through openings in the oscillating membrane and to emit the liquid in the form of an aerosol on the other side of the oscillating membrane, a liquid reservoir to hold the liquid connected to the oscillating membrane to feed the liquid, wherein the membrane constitutes a wall portion of the liquid reservoir, a sealing element arranged on an opening in the liquid reservoir to provide a gas-tight seal for the opening, and a slidable element connected to the sealing element in such a way that a movement of the slidable element effects a movement of at least one section of the sealing element whereby a negative pressure is generated in the liquid reservoir so that the liquid presently fed to the membrane is under negative pressure.
