Abstract: A conventional liquid spray gun having a compressed air supply equipped with a liquid, e.g. paint, container for supplying the liquid to be sprayed onto a target surface. The container has a closed bottom, an open top and a cylindrical sidewall. A removable cover is attached over the open top of the container, and the cover has a pair of apertures extending through it, one of which holds a proximal end of a rigid tube whose distal end extends to a point close to the container's bottom. Slidingly mounted on the rigid tube is a generally circular, movable plunger whose periphery engages the cylindrical sidewall of the container.

Abstract: An atomizer provides a control of duty cycle or a motor driving a diaphragm pump. By providing precise, high-speed flow through an eductor nozzle, improved atomization occurs. However, to control the total volume of atomized liquid discharged, the delay time between operational time periods may also be controlled. Thus, a very effective atomizer provides economical use of essential oils by control duty cycle. Precision modeling provides highly integrated subsystems providing superior performance and reliability.
