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 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. A pair of diverging fluid flow passages have a common connection with said power nozzle and respective bounding walls, each respective bounding wall diverging from the centerline no more than about 50°, and a splitter defining respective inner walls of said pair of diverging walls, the splitter being spaced a distance of about 3W from the power nozzle. Inflatable bladder(s) connected to the diverging fluid flow passage(s), and a vent connected to the other of said fluid flow passages.
