Abstract:
1. A device, comprising: an inlet; an outlet chamber; a first passage in fluid communication with the inlet, terminating at the outlet chamber and having a first resistance to fluid flow of a viscosity; a second passage in fluid communication with the inlet, terminating at the outlet chamber and having a second, different resistance to the fluid flow of the viscosity, the first and second passages oriented along different trajectories at the outlet chamber to form a combined flow in the outlet chamber and cause fluid flow from the first passage to influence which of a plurality of trajectories the resulting combined flow tends to flow; and a third passage in fluid communication with the inlet, terminating at the outlet chamber and having a third resistance to the fluid flow of the viscosity different from both of the first and second resistances to the fluid flow of the viscosity, the third passage oriented along a different trajectory at the outlet chamber than the first and second passages and fluid flow.
