FLUID OSCILLATOR WITH EXTENDED SLOT

摘要

The invention relates to a fluidic oscillator that is symmetrical about a longitudinal plane of symmetry (P), the oscillator comprising an opening (22) enabling a fluid to enter into an "oscillation" chamber (24) in the form of a two-dimensional fluid jet oscillating transversely relative to said plane of symmetry (P), an obstacle (26) occupying the major portion of said oscillation chamber and possessing a front wall (40) provided with a cavity (42) situated facing said opening and swept over by the fluid jet in oscillation, the oscillator being characterized in that two side walls (34, 36) extend on either side of the opening (22) and form a nozzle inside the oscillation chamber extending towards the obstacle and having a longitudinal dimension that is less than the distance between the opening and the front wall of the obstacle.
