BACKLOAD FLUIDIC SWITCH WITH IMPROVED PRESSURE RECOVERY

摘要

a backload-responsive fluidic switch having high pressure recovery of more than 50% comprises a body member with a power nozzle (PN) having a width W and a centerline CL which is adapted to be coupled to a source of fluid under pressure for issuing a jet of fluid along the centerline (CL). A pair of diverging fluid flow passages (16, 18) have a common connection with said power nozzle (PN) and respective bounding walls, each respective bounding wall diverging from the centerline (CL) no more than about 50 degrees, and a splitter (40) defining respective inner walls of said pair of diverging walls (A2), the splitter (40) being spaced a distance of about 3W from the power nozzle. Inflatable bladder(s) (12, 13) connected to the diverging fluid flow passage(s), and a vent (V1, V2) connected to the other of said fluid flow passages.
