Abstract
A zero sack volume fluid flow regulator generates upstream turbulence for control of fluid flow, fluid spray distribution and fluid droplet size. The fluid flow regulator includes a seal layer for selectively controlling fluid flow. The seal layer is resiliently movable relative to a base layer to selectively constrict a turbulence inducing intermediate channel within the regulator and selectively control fluid flow. A method of fabricating the fluid flow regulator utilizes a multilayer resist process in conjunction with a multilayer electroforming process.
