Abstract
A vehicle fluidic oscillator for causing a jet of liquid to repeatedly sweep through a selected fan angle has a power nozzle coupled to a source of liquid under pressure, an oscillation chamber having an upstream end and a downstream end with the power nozzle at the upstream end, and an outlet to ambient at the downstream end. A pair of opposed control ports are provided at the upstream end, and sidewalls which diverge from the upstream end and then converge towards the outlet. A pair of control passages connect the downstream end of the oscillation chamber with the control ports, respectively, and a pair of bypass passages, one for each control passage, respectively, connect each control passage with the source of liquid under pressure. A method of adapting a fluidic windshield washer nozzle oscillator to iterations in vehicle designs is carried out by adjusting the widths of the bypass passages in accordance with iterations in such vehicle design to: a) reduce the product design cycle time and b) reduce total system cost.
