[0054] FIG. 1 illustrates an embodiment of the present invention 10, referred to as a spray gun 10. The spray gun 10 is shown as being connected to two fluid intake tubes 140. Each of the intake tube 140 is connected at one end to a left intake member 50 and a right intake member 55 near the proximal end 180 of the spray gun 10, and the opposed end of the intake fluid tube 140 may be connected to a fluid canister 150. The fluid canister 150 may contain the material that is sprayed by the spray gun 10.

[0055] Also, a mixing nozzle control tube 130 is shown at one end connected to a mixing nozzle pressure control 105, and at the other end to an air pressure means 170.

[0056] In one embodiment, a mixing nozzle 100 is disposed at a distal end of the spray gun 10. A mixing nozzle pressure control 105 can be operationally connected to one end of a mixing nozzle control tube 130 to control the airflow into a vortex aperture 175, as seen in FIG. 7.

[0057] When the intake fluid tube 140 is connected to the left intake member 50, and when the left trigger 40 is pulled rearwardly, the material in the respective fluid canister 150 is displaced from the fluid canister 150, through the intake fluid tube 140, through the left intake member 50, through the left chamber 30, through the left chamber fluid dispenser 90 (as seen in FIG. 3), through the vortex means 115 (FIG. 5), then through the mixing nozzle aperture 120, to be sprayed on a desired surface.

[0058] When the intake fluid tube 140 is connected to the right intake member 55 and the left intake member 50, then the material from each separate fluid canister 150 is thoroughly mixed in the mixing chamber 115 if both triggers are displaced rearwardly.

[0059] FIG. 2 illustrates an embodiment of the spray gun 10 with a unison movement means 70 or a trigger pin 70 disposed through both triggers 40, 45 so they both move in unison. FIG. 2 also illustrates the spray gun handle 160, the fluid control valves 60 which control the amount of material displaced or flowing through the respective chamber 30, 35, and the respective left chamber fluid dispenser 90 and right chamber fluid dispenser 95.

[0060] FIG. 2 illustrates the spray gun 10 not connected to any intake fluid tube 140 or any mixing nozzle control tube 130.

[0061] FIG. 2 also shows a face 25, at the distal end 190 of the spray gun 10, which contains a left chamber fluid dispenser 90, and a right chamber fluid dispenser 95. The fluid dispensers 90, 95 are apertures that allow for a substance from the fluid delivery system, which may be a canister 150 to be discharged therefrom.

[0062] FIG. 3 shows the spray gun 10 without the trigger pin 70. Thus, the left trigger 40 and right trigger 45 can be independently operated. For example, as illustrated in FIG. 3, the left trigger 40 is shown as pulled or displaced rearwardly. This position allows the material to flow through the left intake member 50, through the left chamber 30, and out of the left chamber fluid dispenser 90.

[0063] The independent trigger operation allows the user to test the flow of the material to make sure that the material flows out of the left chamber fluid dispenser 90 at the same rate as the right chamber fluid dispenser 95.

[0064] If, for example, fluid or material is flowing out of one chamber 30, 35 at a slower rate of speed then the other chamber 35, 30 then the user can adjust this problem by adjusting pressure at the fluid delivery system. And the fluid control valves 60 can be used to fine tune the pressure.

[0065] Once the fluid flow from each dispenser 90, 95 is equal, the user may insert the trigger pin 70 through both triggers 40, 45 to move in unison.

[0066] FIG. 4 illustrates one embodiment of the spray gun 10, with a mixing nozzle 100 disposed immediate adjacent to the face 25 so that any material emanating from the left chamber fluid dispense 90 or right chamber fluid dispenser 95 enter the vortex means 115 (FIG. 5), and then is displaced through the mixing nozzle aperture 120.

[0067] FIG. 4 also illustrates a supply line aperture 200, also called a supply line aperture 200 disposed in the supply line member 210. The supply line aperture 200 may be aligned to dispose matter, fluid, or air displaced through the supply line aperture 200 enters the displacement intake means 175, also called the vortex aperture 175, and then enters the mixing chamber 115. Because the vortex aperture 175 may have a smaller opening then the supply line aperture 200, the velocity of the matter, fluid, or air is increased as it enters the mixing chamber 115, thus mixing the matter, foam, fluid that is in the mixing chamber 115, before being forced through the mixing nozzle aperture 120.

[0068] The matter mixed by the present invention may be a reactive chemical. The matter may be fluid, gas, liquid or air. The matter could also be solid. The matter may be a polyurethane or polyuria.

[0069] In one embodiment, foam in the mixing chamber 115 can be mixed under pressure of between about 30 psi to 120 psi. Matter can also be mixed with other pressures, beneath 30 psi or above 120 psi.

[0070] FIG. 5 illustrates that the proximal end of the mixing nozzle 100 that contacts the face 25 has a curved edge 220, also called a vortex aperture 175, which may extend inwardly in the shape of a concave-curved surface 115, referred to as a mixing chamber 115. In one embodiment the mixing chamber 115 has a radius 195 and extends from the vortex aperture 175 to the mixing nozzle aperture 120.

[0071] FIG. 5 illustrates one embodiment of the mixing nozzle 100 having one vortex aperture 175. However, there may be more than one vortex aperture 175.

[0072] FIG. 9 illustrates an embodiment where the mixing nozzle 100 may have three vortex apertures 175. The mixing nozzle 100 may have a concave portion 250 that extends from the vortex aperture 175 inwardly and towards the distal end to the mixing nozzle aperture 120. The vortex apertures 175 may have a cut-out portion 290, best seen in FIG. 10. The cut-out portion 290 may extend inwardly to form a small channel 270 near the edge in a direction so as to direct fluid or air in the mixing chamber 115 in a circular direction 290. In one embodiment the channel 270 has a partial spiral as in FIG. 5, or a more linear channel as seen in FIG. 9. The more linear shaped channel may produce a higher velocity violent shearing action. The partial spiral shape may produce a lower velocity gentler mixing action. Other shaped channels can be used, to vary the mixing action.

[0073] FIG. 4 also illustrates a supply line member 210 that may attach the mixing nozzle 100 to the face 25, so that when air pressure is applied through the supply line aperture 200, it then enters the vortex aperture 175. Thus, when material is dispensed from the left chamber fluid dispenser 90 and the right chamber fluid dispenser 95, air enters the vortex aperture 175 and forces the separate materials to mix within the mixing chamber 115, and then the mixed materials are dispensed through the mixing nozzle aperture 120 in equal ratios if desired.

[0074] FIGS. 6 and 7 illustrate an embodiment of the mixing nozzle 100 adjacent to the face 25, with the vortex aperture 175. In another embodiment, the mixing nozzle 100, vortex aperture 175, mixing chamber 115 may be integral with the face 25.

[0075] FIG. 8 illustrates a sectional view of the configuration of the supply line aperture 200, also referred to herein as the first matter supply aperture 200. Matter, such as fluid or air may be forced through the vortex aperture 175, also called the displacement intake means 175 and into the mixing chamber 115. The air may swirl around at high velocity causing matter from the left chamber fluid dispenser 90 and the right chamber fluid dispenser 95 to mix together and enter the mixing nozzle aperture 120. The mixed matter or foam can then be sprayed onto a desired surface.

[0076] FIG. 9 illustrates an embodiment of the mixing nozzle 100 having three equally spaced vortex apertures 175, and a concave portion that extends to a mixing nozzle aperture 120. FIG. 9 also illustrates the vortex aperture 175 is formed of a small channel 270 to direct fluid direction in mixing chamber in a circular motion.

[0077] Although this mixing nozzle 100 is shown separate from the face 25 (FIG. 3), it may be integral with the face 25, and be one unit.

[0078] FIG. 10 illustrates an embodiment of the vortex aperture 175 having a horizontal distance 230 of about 1/16″, a proximal end diameter 240 of about ¾″ and a distal end radius 260 of about ½″. Although these dimensions are only examples and these may vary.
