  • Modular system for atomizing a liquid
    Patent number: 6056213
    Abstract: A modular system for atomizing and delivering liquids to a substrate. The modular system comprises a liquid module, a means for providing an atomizing agent, a nozzle assembly and an actuator which is changeable between a first closed position and a second open position, for selectively allowing the atomizing agent to flow from the means for providing atomizing agent to the atomizing agent channel and for selectively allowing the liquid to flow from the cavity to the liquid delivery nozzle. The modular system atomizes liquids into a narrow distribution of particle sizes without the use of propellants or solvents. The modular system has replaceable liquid and atomizing agent modules. A method for atomizing liquids is also disclosed.
