Nozzle for spraying liquids

A nozzle for spraying liquids comprising a nozzle housing and a plurality of outlet openings in the nozzle housing, wherein each outlet opening of the plurality of outlet openings is arranged at an end of one of a plurality of outlet passages through a wall of the nozzle housing, and wherein the plurality of outlet openings are arranged in a circle along at least one imaginary circular line on the nozzle housing, wherein an outlet angle which a respective central axis of one of the plurality of outlet passages associated with one of the plurality of outlet openings encloses with a central longitudinal axis of the nozzle housing differs between at least one first outlet opening, at least one second outlet opening and at least one third outlet opening of the plurality of outlet openings, wherein the nozzle is designed as a dual-substance nozzle having an internal mixing chamber, and wherein the internal mixing chamber has a liquid inlet and a gas inlet, wherein the internal mixing chamber is of annular design, wherein the plurality of outlet passages start from the internal mixing chamber, wherein a conical distribution wall is provided, wherein the internal mixing chamber adjoins a circumferential edge of the conical distribution wall, and wherein mouth inlets of the plurality of outlet passages on an inside of the wall of the nozzle housing are situated on a common imaginary circular line, and wherein in a sectional view onto a sectional plane containing the central longitudinal axis, an outer wall of the internal mixing chamber forms a pair of straight lines and a peripheral wall of at least one of the plurality of outlet passages continues from an end of the outer wall of the internal mixing chamber and diverges away from the central longitudinal axis.
