A fluidic oscillator (1) which is symmetrical about a longitudinal plane of symmetry (P) includes elements (10, 14, 16) for generating an oscillating two-dimensional fluid jet, an obstacle (24) with a cavity (40) impinged upon by the oscillating jet in the front portion (26) thereof, and a longitudinal member (54, 58, 60, 62) arranged in the empty space (38) downstream from said obstacle for partially dividing said space into two identical areas (38a, 38b) while forming at least one fluid communication channel (56, 64, 66, 68) therebetween. A fluid flowmeter comprising said fluidic oscillator is also disclosed.
L'invention a pour objet un os- cillateur fluidique (1) symétrique par rapport à un plan de symétrie longitu- dinal (P) comprenant des moyens (10, 14, 16) pour engendrer un jet de flu- ide bidimensionnel osciliant, un obsta- cle (24) pourvu dans sa partie frontale (26) d'une cavité (40) balayée par le jet en oscillation et un élément longitudinal (54, 58, 60, 62) disposé dans l'espace libre (38) situé en aval dudit obstacle de manière à séparer partiellement ledit espace en deux zones identiques (38a, 3ab), en ménageant entre celles-ci au moins un canal de communication (56, 64, 66, 68) pour le fluide. L'invention a également pour objet un compteur de fluide en écoulement comportant un tel oscillateur fluidique.
