FLUIDIC CIRCUIT WITH ATTACHED COVER AND METHOD

摘要

A fluidic oscillator and method in which a first molded portion (30) comprises a first part having an oscillator circuit silhouette formed in one surface. The oscillator circuit silhouette has a power nozzle (15'), an oscillation chamber (16), 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 (17, 18) in the oscillation chamber. A closure seal plate part (32) is hingedly connected to the fist part such that the closure seal plate can engage the oscillation silhouette. A second molded portion has a recess (47, 48) adapted to forcibly receive the first portion with the closure seal plate engaging the oscillation silhouette. Interfitting protuberances (45, 46) and recesses prevent sliding between the first part and the closure seal part when they are forced into the recess.
