A <DEL-S DATE="20030304" ID="DEL-S-00001"/>vehicle washer nozzle<DEL-E ID="DEL-S-00001"/> <INS-S DATE="20030304" ID="INS-S-00001"/>liquid spray <INS-E ID="INS-S-00001"/>system having a source of washer liquid under pressure, a fluidic oscillator comprising a housing and a fluidic insert having a power nozzle, an oscillation chamber having an upstream end coupled to the power nozzle for issuing a jet of <DEL-S DATE="20030304" ID="DEL-S-00002"/>washer<DEL-E ID="DEL-S-00002"/> liquid into the oscillation chamber and a downstream end having an outlet aperture for issuing a jet of <DEL-S DATE="20030304" ID="DEL-S-00003"/>wash<DEL-E ID="DEL-S-00003"/> liquid to ambient, and side and top and bottom walls, an oscillation inducing silhouette in the oscillation chamber for causing said jet of <DEL-S DATE="20030304" ID="DEL-S-00004"/>wash<DEL-E ID="DEL-S-00004"/> liquid to rhythmically sweep back and forth between the sidewalls in the oscillation chamber. Top and bottom walls of the oscillation chamber first diverge for a predetermined distance in a downstream direction and then converge towards each other through said outlet aperture. This enables the deflection angle to be adjusted for different <DEL-S DATE="20030304" ID="DEL-S-00005"/>vehicles<DEL-E ID="DEL-S-00005"/> <INS-S DATE="20030304" ID="INS-S-00002"/>uses <INS-E ID="INS-S-00002"/>and applications by changes to the fluidic insert without changes to the housing.
