Abstract:
1. A sprayer comprising: a first liquid supply comprising a first liquid having a first composition; a second liquid supply comprising a second liquid having a second composition different from the first composition; a gas supply comprising a gas; a nozzle comprised of an outer tube possessing an interior, a first internal tube positioned in the interior of the outer tube, and a second internal tube positioned in the interior of the outer tube; the first internal tube possessing an interior, the first internal tube being connected to the first liquid supply so the interior of the first internal tube is in fluid communication with the first liquid supply so the first liquid from the first liquid supply is flowable into the interior of the first internal tube during operation of the sprayer; the second internal tube possessing an interior, the second internal tube being connected to the second liquid supply so the interior of the second internal tube is in fluid communication with the second liquid supply so the second liquid from the second liquid supply is flowable into the interior of the second internal tube during operation of the sprayer; the interior of the outer tube being connected to the gas supply so that the interior of the outer tube is in fluid communication with the gas supply so the gas from the gas supply is flowable into the interior of the outer tube during operation of the sprayer; a coil located in the interior of the outer tube, the coil comprising a plurality of adjacent helical windings defining a fluid passage through an interior of the coil, the interior of the coil configured to be in fluid communication with the interior of the outer tube such that gas flowing into the interior of the outer tube from the gas source during operation of the sprayer flows between the adjacent helical windings and into the interior of the coil; and the interior of the first internal tube configured to be in fluid communication with the interior of the coil so that the first liquid flows through both the first internal tube and the interior of the coil.
