Abstract
A molded fluid device having a power nozzle with a width W and a coupling passage coupling a source of fluid to the power nozzle. The coupling passage is formed on one chip or insert surface and has a planar enlargement and a plurality of posts spaced across the enlargement, the spacing S between each post being less than the width of the power nozzle with the sum of spacing S being greater than the width W. A liquid spray nozzle is formed on an opposing chip surface and connected to the coupling passage downstream of the posts.
