Abstract
An arrangement for washing lenses of headlights has means for conveying a washing liquid, and a nozzle provided with a passage having an inlet portion communicating with the conveying means for admitting the washing liquid into the nozzle and an outlet portion having an open end for issuing the washing liquid from the nozzle. The outlet portion of the passage of the nozzle diverges towards the open end thereof, whereas the open end has a shape such that the flow of the washing liquid issuing from the nozzle has a shape corresponding to the shape of the lens to be washed. The outlet portion of the passage of the nozzle may be formed as a through bore open at an end face of the nozzle facing towards the lens to be washed, and the open end of the thus-formed outlet portion may have a shape corresponding to the shape of the lens. The outlet portion of the passage of the nozzle may also be defined by two grooves formed in a section of the nozzle adjacent to the end face thereof and open at the latter.
