Spray device with at least one cleaning port

摘要

An exemplary device (20) for spray applications includes a nozzle (22) configured to emit a first fluid stream (60) in a downstream direction away from the nozzle (22). At least one feed port (30A...30E) situated near the nozzle (22) introduces an agent into the first fluid stream (60) to be carried by the first fluid stream (60) in the downstream direction. At least one cleaning port (40A...40E) situated near the nozzle (22) emits a second fluid stream (64) in a generally upstream direction toward at least one of the nozzle (22) or the feed port (30A...30E).
