Abstract
A spray director incorporates structure that generates upstream turbulence for control of spray distribution and spray droplet size. A method of fabricating spray director utilizes a multilayer resist process in conjunction with a multilayer electroforming process.
Claims18
A fluid dispersant unit consisting essentially of:
- a plurality of electroformed layers and at least one metallic layer between at least one adjacent pair of said plurality of layers,
- said layers defining a nonlinear fluid pathway comprising an entry orifice for receiving a fluid;
- a fluid ejection orifice for ejecting said fluid;
- and a turbulence inducing intermediate channel between said entry orifice and said fluid ejection orifice for nonlinearly conveying said fluid from said entry orifice to said fluid ejection orifice.

A fluid dispersant unit consisting essentially of:
- a first electroformed layer having at least one entry orifice therein;
- a second electroformed layer having at least one fluid ejection orifice therein;
- a metallic layer between said first and said second layer;
- and
- at least one turbulence-inducing channel extending between said at least one entry orifice and said at least one fluid ejection orifice, said at least one turbulence-inducing channel extending in a direction that is at a non-zero angle to a central axis of at least one of said at lest one entry orifice and said t least one fluid ejection orifice to induce turbulence in liquid flowing from said at least one entry orifice to said at lest one ejection orifice.
