Patent ID: 8820662

Claim:
A nozzle for generating an aerosol from a fluid and a gas, the nozzle comprising: a cone having at least one wettable cone-shaped gas exit channel that widens in a direction of gas flow from a cone apex to a cone base where a lip is provided on the cone, said wettable cone-shaped gas exit channel being connected at the cone apex by an orifice to a nozzle gas supply channel forming an aerosolizing perimeter between the orifice and the cone; and at least one annular fluid exit port encompassing the lip at the cone base, said cone base being connected to a nozzle fluid supply channel so that the fluid to be aerosolized flows from the nozzle fluid supply channel by capillary forces and by negative pressure created by a jet of gas exiting the orifice, the fluid flowing from the annular fluid exit port over the lip of the cone towards the apex of the cone where it is aerosolized at the aerosolizing perimeter.
