What is claimed is: 1. A nozzle device to discharge a fluid, onto vehicle windows and/or lenses of vehicle headlights, having at least one connection furnished at a nozzle body to supply the fluid and having at least one nozzle opening on the nozzle body, which has the characteristics of a slit nozzle and is connected to the fluid connection through a fluid path formed in the interior of the nozzle body, characterized in that at least one rotation chamber is formed in the interior of the nozzle body for the fluid, which chamber has a concave curvature around at least one axis of rotation in at least one partial area of an interior surface bounding the rotation chamber and is enclosed by opposing end wall surfaces, that a mouth of the fluid connection issues eccentrically into the chamber referenced to the axis of rotation, and that the at least one nozzle opening is offset at an angle around the axis of rotation to be substantially non-aligned with respect to the opening of the mouth of the fluid connection. 2. The nozzle device from claim 1, wherein the rotation chamber, at least in a partial area of an inner surface lying between an opening of the fluid connection and the at least one nozzle opening, has a concave configuration. 3. The nozzle device from claim 1, wherein the rotation chamber has a concave configuration over an entire inner surface enclosing the axis of rotation. 4. The nozzle device from claim 1, wherein the rotation chamber, at least on the concave partial area of an inner surface, is configured corresponding to the surface of a body of rotation co-axial with the axis of rotation. 5. The nozzle device from claim 1, wherein the rotation chamber is configured as a circular cylinder shape at least on the concave partial area of its inner surface. 6. The nozzle device from claim 1, wherein the fluid connection forms a passage to supply the fluid, an axis of which passage opens eccentrically into the rotation chamber at the mouth. 7. The nozzle device from claim 1, wherein the fluid connection forms a passage to supply the fluid, and the passage opens into the rotation chamber substantially tangentially referenced to an imaginary circle drawn around the axis of rotation. 8. The nozzle device from claim 1, wherein an opening of the fluid connection and the at least one nozzle opening are provided on the inner surface of the rotation chamber enclosing the axis of rotation. 9. The nozzle device from claim 1, wherein the fluid connection forms a passage to supply the fluid, and the axis of one of the passages of the fluid connection and of the opening lies in a plane substantially perpendicular to the axis of rotation. 10. The nozzle device from claim 1, wherein an opening of the fluid connection and the at least one nozzle opening are furnished offset to each other by an angular amount different than 90째. 11. The nozzle device from claim 1, wherein the nozzle opening is formed by at least one nozzle slit and/or by at least one array of a plurality of nozzle openings. 12. The nozzle device from claim 11, wherein the at least one of the nozzle slit and at least one array of nozzle openings extend over an angular range around the axis of rotation. 13. The nozzle device from claim 11, wherein the at least one of the nozzle slit and the at least one array of nozzle openings are furnished in a plane which lies perpendicular to the axis of rotation and includes an angle with it. 14. The nozzle device from claim 11, wherein one of the at least one nozzle slit and the at least one array of nozzle openings extend along an imaginary helical line around the axis of rotation. 15. The nozzle device from claim 1, characterized by the nozzle device is manufactured from one of metal and plastic. 16. The nozzle device from claim 1, wherein the axis of the fluid connection and the axis of the at least one nozzle opening having the characteristics of a fan lie in a substantially common plane. 17. A nozzle device to discharge a fluid, onto vehicle windows and/or lenses of vehicle headlights, having at least one connection furnished at a nozzle body to supply the fluid and having at least one nozzle opening on the nozzle body, which has the characteristics of a slit nozzle and is connected to the fluid connection through a fluid path formed in the interior of the nozzle body, characterized in that at least one rotation chamber is formed in the interior of the nozzle body for the fluid, which chamber has a concave curvature around at least one axis of rotation in at least one partial area of an interior surface bounding the rotation chamber, that a mouth of the fluid connection issues eccentrically into the chamber referenced to the axis of rotation, and that the at least one nozzle opening is offset at an angle around the axis of rotation with respect to the opening of the mouth of the fluid connection, wherein means to modify the emerging fluid jet are furnished on the outer surface of the nozzle body in the area of the at least one nozzle. 18. The nozzle device from claim 17, wherein the means to modify the fluid jet are formed by a surface extending away from the nozzle body and adjacent the at least one nozzle opening, which surface is one of part of a projection and is profiled. 19. A nozzle device to discharge a fluid, onto vehicle windows and/or lenses of vehicle headlights, comprising: at least one fluid connection furnished at a nozzle body to supply the fluid; at least one nozzle opening on the nozzle body, connected to the fluid connection through a fluid path formed in the interior of the nozzle body; and at least one fluid rotation chamber formed the interior of the nozzle body for the fluid, the at least one fluid rotation chamber having a concave curvature surface around at least one axis of fluid rotation in at least one partial area of an interior surface and enclosed by opposing end wall surfaces, a mouth of the fluid connection issuing eccentrically into the chamber referenced to the axis of rotation to be directed by the concave curvature surface, and the at least one nozzle opening offset at an angle around the axis of rotation to be substantially non-aligned with respect to the opening of the mouth of the fluid connection. 20. The nozzle device of claim 19, wherein the fluid connection forms a passage to supply the fluid, and the passage opens into the rotation chamber substantially tangentially referenced to an imaginary circle drawn around the axis of rotation.
