ABSTRACT:
A windshield washer comprises a nozzle in which a liquid jet is formed and repetitively transversely swept before egressing from the nozzle body. The swept jet breaks up into liquid droplets which impinge upon a wide area of a windshield. In a preferred embodiment the nozzle is an oscillator, preferably a fluidic oscillator, in which the jet is swept oscillatorily between two extreme positions. In still another form of the invention discrete slugs of liquid are alternately issued in at least two directions from a common nozzle body.
