Abstract: A nozzle and a method of generating an inhalable aerosol from a liquid solution or liquid suspension and a gas by operating the nozzle. A column-like aerosol plume is generated having fluid particles within a particle free sheath of gas, the aerosol plume being generated from a compressed gas interacting within the aerosolizing space with a fluid ejected along the central axis, and generates a Venturi effect entraining gas that flows over the convex outer nozzle surface that together with the particle free sheath keeps the circumferential edge and the outer nozzle surface free of particle deposition. An aerosol exit orifice diameter is at least 1.3 times larger than the fluid exit orifice diameter; and a converging annular pressurized gas channel extending at an acute gas flow angle of 10-30° with respect to a central axis.

Abstract: The invention relates to a spray gun apparatus (10) for spraying a fine film coating of liquid, such as paint, lacquer or bond, onto a surface. The spray gun comprises a main body (12) having a fluid throughbore (22), a gas throughbore (16), and a main trigger lever (80) for allowing a user to spray fluid from the gun. A fluid flow adjustment mechanism (52, 58, 74) facilitates adjustment of the quantity of fluid sprayed from the gun for a given displacement of the main trigger lever (80). An engagement surface (86) is provided on the trigger lever and adapted to engage with a corresponding engagement surface (90) of the fluid flow adjustment mechanism. Pivoting movement of the main trigger lever (80) results in translational movement of at least a portion of the fluid flow adjustment mechanism to thereby selectively spray fluid from the gun upon displacement of the main trigger lever.

Abstract: The invention relates to an apparatus for forming liquid droplets, such as a micro nebulizer, useful for preparing samples for subsequent analysis via MS, AA, ICP, CE/MS, and similar analytical systems. The apparatus has a mechanically stabilized inner microtube or needle, thereby ensuring controllably uniform droplet size The mechanical stabilization is provided by securing the inner microtube or needle, such as by narrowing the inner diameter of the outer microtube or otherwise narrowing the annular intermediate space between the inner and outer microtubes for a predetermined length. Thus, the inner microtube is secured in a centered or otherwise predetermined fixed radial position, with minimum perturbation of the fluid flow. Further, a tip, when coupled with the exit end of the outer microtube, provides a region in which the sheath fluid flow in the outer microtube stabilizes prior to both exiting the tip and colliding with the liquid analyte exiting the inner microtube.

Abstract: A spray gun nozzle head for atomizing a liquid using a flowing pressurized gas. The nozzle head includes a central nozzle having an orifice for supplying the liquid to be atomized. A cap having a funnel shaped chamber is mountable over the nozzle to define an annular passage for supplying the pressurized gas. The cap has an orifice alignable with the nozzle orifice such that the nozzle orifice is recessed upstream from the cap orifice to define a region adjacent the nozzle orifice in which the liquid is atomized by the pressurized gas into a liquid spray prior to being expelled through the cap orifice.

Abstract: An improved air atomizing spray gun accommodates selective control over flows of air for atomizing liquid coating material into a conically-shaped spray and for forming the spray into a fan-shaped pattern. In one arrangement of the gun structure, respective supplies of atomizing and fan-shaping air are connected to the gun and separately coupled to atomizing and fan air outlet orifices. In another arrangement, only the supply of atomizing air is connected to the gun, and a valve on the gun adjustably diverts a portion of the atomizing air for fan-shaping purposes.
