Title: FLUIDIC DIODE CHECK VALVE
Abstract:
Fluidic diodes are disclosed that have a housing defining an inlet and an outlet and a divided fluid passageway therebetween defined by mirror image partitions generally tear¬ drop shaped spaced apart a first distance from one another by a constant width primary fluid pathway with the tip thereof pointed generally toward the outlet and spaced apart a second distance from an interior wall of the housing to define a constant width secondary fluid pathway. Fluid flow from the inlet to the outlet is through the primary fluid pathway with some additional flow through the secondary fluid pathways joining the primary fluid pathway proximate the outlet for flow together in the same direction, and fluid flow from the outlet to the inlet through the secondary fluid pathways exits the secondary fluid pathways into the primary fluid pathway, proximate the inlet, in a direction substantially opposite the flow in the primary fluid pathway.
