PROCEDE ET DISPOSITIF POUR DIRIGER UN ECOULEMENT D'UN FLUIDE PAR UNE TUYERE AYANT UNE CAPACITE D'ECOULEMENT DIRECTIONNEL REGLABLE

摘要

A fluid passing through a nozzle operative on the principle of wall effect of fluidic devices is variously deflected. A pair of control valves are provided at control fluid passages for supplying control jets into the throat portion of the nozzle in order to control the deflection of fluid flowing therethrough. A continuous straightforward flow is generated by simultaneous opening of said control valves.
