NOZZLE SYSTEM FOR A LIQUID DISCHARGE DEVICE, COMPRISING A NOZZLE AND NOZZLE HOLDER AND/OR COUPLING NUT

摘要

The invention relates to a nozzle system for a liquid discharge device, comprising a nozzle and a device which fixes the nozzle in the discharge device. The device comprises a liquid reservoir which pressurises the liquid through a nozzle in order to discharge liquid. The nozzle is fixed to the discharge device by a holding device. Said holding device can be automatically maintained by a second holding device, e.g. in the form of a coupling nut, or the coupling nut is the holding device. According to the invention, at least one part of the outer surface of the holding device is micro or nanostructured.
