NOZZLES WITH INTEGRATED OR BUILT-IN-FILTERS AND METHOD

摘要

A molded fluidic device (20) having a power nozzle (PN1, PN2) with a width (W) and a coupling passage (21) coupling a source of fluid (22) to said power nozzle (PN1, PN2). The coupling passage (21) has a planar enlargement and a plurality of posts (24-1, 24-2...24-N) spaced across the enlargement, the spacing (S) between each post (24-1, 24-2...24-N) being less than the width (W) of the power nozzle (PN1, PN2) with the sum of spacing (S) being greater than the width (W).
