1. An apparatus for aspirating and aerosolizing a liquid in a flow of gas under pressure comprising:

  • a housing defining a liquid reservoir with walls of a predefined three dimensional geometric shape, an aerosol outlet located at a first axial end of said reservoir and a gas nozzle formed at a second axial end of said reservoir, said nozzle having means for connecting to a pressurized gas source;

    an internal component having an operative position and being formed of a substantially flat member having an axial dimension and shaped along same to conform substantially with said reservoir along a bisecting cross section thereof, said internal component having a cylindrical liquid conduit with a first axial end connected to said internal component and a second axial end distal therefrom, said liquid conduit surrounding said gas nozzle when in said operative position;

    wherein said internal component and said cylindrical liquid conduit form a minimal capillary space between, respectfully, said walls of said liquid reservoir and said gas nozzle, said cylindrical liquid conduit having a liquid orifice at said second axial end, wherein said gas nozzle and said liquid orifice are in fluid communication with said minimal capillary space.
