ABSTRACT:
The invention relates to a nozzle system for a delivery device for liquids, wherein the nozzle system comprises a nozzle and a device which fixes the nozzle in the delivery device. The delivery device, an atomiser, has a liquid reservoir from which a liquid is forced through the nozzle under pressure. The nozzle fixing means may itself be secured by a second fixing, e.g., in the form of a check nut, or the fixing may itself be a check nut. According to the invention the fixing means on the nozzle outlet side has a specific geometry which minimizes the proportion of dispensed liquid deposited on the fixing means.Preferably, the present invention is part of a propellant-free device for nebulizing pharmaceutical liquids.
