<p>Fluidic oscillator and flow meter comprising such a fluidic oscillator comprising a fluid intake (3) capable of forming a two-dimensional jet; an obstacle (16) having a front part in the form of a chamber (8) opposite the intake (3) in the course of the jet, this chamber (8) comprising two walls (22, 23) which are symmetrical with respect to a longitudinal plane of symmetry (2) passing through the said intake (3), the walls (22, 23) joining on this plane (2); and means for alternately increasing the pressure on each of the side faces of the obstacle (16) in the vicinity of the front part in relation to an oscillation of the jet between the walls of the chamber (8). <IMAGE></p> |
