MICROSTRUCTURED HIGH PRESSURE NOZZLE WITH AN IN-BUILT FILTER FUNCTION

摘要

The invention relates to a microstructured nozzle comprising a plurality of channels which are produced by microstructuring a plate-like body. The channels of said nozzle are disposed between projections which are arranged in rows next to each other and which project out of the base plate. Said microstructured base plate is covered with a cover plate. The channels are defined within narrow boundaries according to shape, cross-sectional area and length. Said nozzle contains a filter as a primary structure and a secondary structure is arranged downstream from the filter. The nozzle is, for example, used with a sprayer enabling an aerosol to be produced from a liquid which contains a medicament.
