ABSTRACT:
A fluidic oscillator and method in which a first molded portion comprises a first part having an oscillator circuit silhouette formed in one surface. The oscillator circuit silhouette has a power nozzle, an oscillation chamber, with upstream and downstream ends, a power nozzle at the upstream end adapted to receive a liquid under pressure and an outlet to ambient at the downstream end, and oscillation inducing elements in the oscillation chamber. A closure seal plate part is hingedly connected to the first part such that the closure seal plate can engage the oscillation silhouette. A second molded portion has a recess adapted to forcibly receive the first portion with the closure seal plate engaging the oscillation silhouette. Interfitting protuberances and recesses prevent sliding between the first part and the closure seal part when they are forced into the recess.
