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.

The nozzle system according to claim 15, characterized in that the spacing a of the nozzle apertures is in the range between αum and 105 um. 18. The nozzle system according to claim 1, characterized in that in the assembled state only the nozzle holder extends into the area in front of the nozzle apertures (11). 19. The nozzle system according to claim 1, characterized in that the nozzle is formed from at least two construction units. 20. A delivery device for liquids, characterized in that it comprises a nozzle system according to one of claim 1. 21. A delivery device according to claim 20, characterized in that the device comprises a lower and an upper housing part mounted to be rotatable relative to one another, the upper part of the housing containing a spring housing with spring which is tensioned by rotating the two housing parts by means of a locking clamping mechanism preferably in the form of a screw thread or gear and is released by pressing a release button on the upper part of the housing, the spring meanwhile moving a power take-off flange connected to a hollow piston on the lower end of which a container can be fitted and at the upper end of which are found a valve and a pressure chamber which is connected for fluid transmission to the nozzle or the nozzle system formed in the upwardly open part of the upper housing part. 22. A delivery device according to claim 21, characterized in that the device is an inhaler or some other atomizer for medicinal liquids. 23. A delivery device according to claim 1, characterized in that it is an atomizer for pharmaceutical liquids. 24. A delivery device for liquids, comprising: a nozzle having at least two nozzle apertures arranged so that jets leaving the nozzle apertures are aimed towards one another at an angle α; a nozzle holder in which the nozzle is disposed, where the nozzle holder extends at least partially into an area in front of the nozzle apertures, the nozzle holder including an inner recess, which begins on a side adjacent to an end face of the nozzle and extends as far as the outside of the nozzle holder parallel to the end face of the nozzle, wherein the inner recess, when viewed from the end face of the nozzle, widens out steadily and continuously in a direction of the outside of the nozzle holder parallel thereto; and a lower and an upper housing part mounted to be rotatable relative to one another, the upper housing part containing a spring housing and spring, which is tensioned by rotating the two housing parts by means of a locking clamping mechanism, and which is released by pressing a release button, wherein the spring is operable to move a power take-off flange connected to a hollow piston on a lower end of which a container can be fitted and at the upper end of which a valve and a pressure chamber are disposed, which pressure chamber is connected for fluid transmission to the nozzle in an upwardly open part of the upper housing part.
