Fluid oscillator with an extended slot |
摘要 |
The invention relates to a fluidic oscillator that is symmetrical about a longitudinal plane of symmetry, the oscillator comprising an opening enabling a fluid to enter into an "oscillation" chamber in the form of a two-dimensional fluid jet oscillating transversely relative to said plane of symmetry, an obstacle occupying the major portion of said oscillation chamber and possessing a front wall provided with a cavity situated facing said opening and swept over by the fluid jet in oscillation, wherein two side walls extend on either side of the opening 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.
