Method to mix and discharge fluids, preferably paints; involves using spray unit with compressed air, where vacuum cone is generated at nozzle point of spray unit, to suck fluids from ink channel body

摘要

The method involves using a spray unit with compressed air. A vacuum cone is generated at a nozzle point of the spray unit, to suck the fluids from an ink channel body. The fluids experience a strong particle collision inside the vacuum cone and are continuously mixed. The ink channel bodies are arranged in the central air stream. The negative cone produces a strong rotational turbulence to concentrate the flow of the air and ink. An Independent claim is included for a unit to mix several paints.
