PURPOSE: A fluid amount adjusting apparatus being combined to an upper stream generation and a power-generating instrument for controlling the fluid amount are provided. CONSTITUTION: 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 (5) for selectively controlling fluid flow. The seal layer (5) is resiliently movable relative to a base layer (3) to selectively constrict a turbulence inducing intermediate channel (10) 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.
