ABSTRACT:
The present invention pertains to improved manually operated atomization systems which combine atomizing nozzles with high pressure, pre-compression type pump mechanisms in order to provide a consistent, high quality, finely-atomized spray of a comparatively higher viscosity fluid. The pre-compression pump mechanism ensures that the product will only be delivered when sufficient pressure is available for atomization regardless of the speed or authority with which the pump mechanism is actuated. When the fluid is discharged from the nozzle in a swirling, conical film, the fluid is broken up into a finely-dispersed mist which may then be directed toward the surface to be coated. Pump mechanisms for use with the present invention incorporate specific design features which facilitate the flow of comparatively viscous fluids with reduced flow resistance and hence reduced pressure losses, as well as providing enhanced structural integrity to better withstand such operating pressures and forces while providing improved reliability. The combination of pre-compression and comparatively higher operating pressures ensures that the comparatively higher viscosity fluid will be delivered to the nozzle with a pressure (and hence a velocity) that is comparatively high and within a comparatively narrow range. This in turn ensures a finely-dispersed product spray with a comparatively narrow range of particle sizes, under a wide range of actuation circumstances.
