Apparatus and Method for Generating an Aerosol

[0006]In general terms, the present invention is directed to an apparatus and a method of generating aerosol doses from a dry powder source with a highly pressurized gas and thereby provide means that improve aerosol quality and the load capacity also from powders with a strong cohesiveness and a great ability to withstand deagglomeration.

[0007]The present invention is directed to an aerosol generating apparatus comprising an at least partially spherical powder chamber for loading and mixing powder with pressurized gas, having one or several compartments, at least two pressure conduits operably connected to a pressure chamber for introducing pressurized gas to the powder chamber by at least two inlet orifices and an ejection conduit opening at an exit orifice to ambient pressure. The apparatus is further characterized in that it has a main axis of rotational symmetry, in that the at least two inlet conduits have each a symmetry axis extending into projection lines and are arranged to a
