Abstract
The present invention pertains to improved atomization systems for comparatively higher viscosity liquid products. More particularly, the present invention provides an improved product delivery system which combines a pre-compression type pump mechanism with a nozzle having two or more orifices configured to discharge corresponding jets or streams of the product which impinge upon one another to provide a finely dispersed spray. 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, pressure within the pump will accumulate without product discharge until a lower pressure threshold is reached, at which time a valve opens to permit product discharge with sufficient pressure for atomization. When the fluid streams impinge upon one another, the fluid is broken up into a finely dispersed mist which may then be directed toward the surface to be coated. In a configuration particularly well-suited for comparatively higher viscosity fluids, the nozzle assembly of the product delivery system imparts additional relative velocity to the jets by introducing a swirl component of velocity prior to impingement, thus enhancing the atomization of the product.
