| 摘要 |
<p>The invention relates to a fluidic oscillator (20) which is symmetrical with respective to a longitudinal symmetry plane (P), comprising a fluid inlet (22) intended to form a bidimensional fluid jet which oscillates transversally with respective to the symmetry plane (P), an obstacle (28) wherein is arranged a cavity (32) which faces said fluid inlet (22) and which is scavenged by the oscillation jet, characterized in that the obstacle (28) has a front wall (30) which has two so-called front surfaces (34, 36) substantially planar and framing the cavity (32), the plane of each surface being substantially perpendicular to the symmetry plane (P), said cavity (32) being defined by a surface which is substantially parallel to said plane (P) at the points (A1, A2) where said surface joins each of said front surfaces (34, 36), the obstacle (28) also having two side walls (38, 40) of which said side surfaces are substantially parallel to the symmetry plane (P) at the points (B1, B2) where each of them joins the corresponding front surface.</p> |
