Abstract:
1. A nozzle apparatus comprising: an intake block having a liquid intake opening, a gas intake opening substantially parallel to and offset from said liquid intake opening, and an outlet opening substantially perpendicular to said liquid intake opening, said outlet opening having an outer region extending between an external surface of said block and an internal thread, said outer region being substantially cylindrical and substantially uniform, said outlet opening further having an inner region of a diameter smaller than said outer region that extends between said outer region and an internal thread, said inner region being substantially cylindrical and substantially uniform; a one-piece inner tube having a lumen, a first externally threaded end, a second internally threaded end, a flange adjacent said first end, said first end being threaded into said inner region of said block so that said inner tube flange contacts a portion of said block to form a substantially fluid-tight seal; a one-piece outer tube having a lumen, a proximal threaded end and a distal threaded end, said proximal end being threaded into said outer region of said block so that a portion of said tube contacts a portion of said block to form a substantially fluid-tight seal and at least a portion of said outer tube surrounds at least a portion of said inner tube; a one-piece tip member having a lumen, a threaded end, a narrowing end, and a flange, said tip member lumen having a portion with a substantially constant diameter and a narrowing portion at least partially within said narrowing end, said tip member flange having a plurality of flutes for allowing gas through and changing the motion of said gas, said tip member being threadedly connected to said second end of said inner tube so that said tip member flange contacts a portion of said inner tube to form a substantially fluid-tight seal; and a cap member having a lumen, a rearward end having an opening of said cap member lumen and a forward end having an opening of said cap member lumen that is smaller than said opening of said rearward end, said cap member being threadedly connected to said distal end of said outer tube so that said rearward end contacts a portion of said outer tube to form a substantially fluid-tight seal, wherein said lumens of said inner tube and said tip member form a passage for liquid, said passage having no structure inside it.
