US Patent 7472847 Fluidic device

For achieving a fluidic device, being able to be made small in sizes, comprising a fluid inflow opening 1, a connector duct 2, and a fluid jet nozzle, wherein the connector duct 2 is constructed with curves, and is further constructed with two (2) pieces of flow passages, being symmetric on both sides. Constructing the connector duct with the curves reduces resistance of fluid within the duct, and further dividing the connector duct into two (2) parts in both side enhances the flows at confluent point in the duct (increase of the flow velocity).
