Patent ID: 7284713

Claim:
A nozzle system, comprising: a nozzle having at least two nozzle apertures and a nozzle holder and optionally a check nut, wherein: the nozzle apertures or the nozzle channels opening into the nozzle apertures are arranged so that the jets leaving the nozzle apertures are aimed towards one another at an angle α, the nozzle is arranged in the nozzle holder and this is optionally fixed by a check nut, and in the assembled state the nozzle holder or the check nut or both extend at least partially into the area in front of the nozzle apertures, characterized in that: in the assembled state the nozzle holder or, if the nozzle system has a check nut, the nozzle holder together with the check nut has an inner recess, which begins on the side adjacent to an end face of the nozzle and extends as far as the outside of the nozzle holder parallel thereto or, in the case of a check nut, as far as the outside thereof parallel to the end face of the nozzle, which, viewed from the end face of the nozzle, widens out steadily and continuously in the direction of the outside of the nozzle holder parallel thereto or, in the case of a check nut, the outside of said check nut parallel thereto, and the nozzle is formed from at least two superimposed plates, at least one of the plates having a second microstructure so that the plates lying one on top of the other define, on one side, a liquid inlet connected to a channel system and/or a filter system which then opens into one or more liquid outlets.
