FIELD: ventilation.SUBSTANCE: device refers to control devices of right, left air flow direction. It includes right, left flow deviation deflectors and connection tie rods. Each right, left flow deviation deflector includes a basic part, a setting plane perpendicular to the central rotation axis of a rotation axis, a flat part and a connection projection projecting out of the basic part. Each connection tie rod includes a tie rod body, connection holes, projecting parts of the tie rod body, which are arranged on one lateral edge of the tie rod body so that they correspond to the connection holes respectively and convex contact parts arranged along the edges of the projecting parts of the tie rod body respectively; with that, convex contact parts are located above the tie rod body. At forward air direction blowdown, the parts near the connection holes of the connection tie rod are retained by means of the corresponding connection projections, thus preventing separation from the connection projections, and vertexes of the convex contact parts and the parts near the other lateral edge are in contact with the corresponding basic parts so that the connection tie rod is subject to deformation at bending.EFFECT: possible suppression of vibrations of deflectors at right, left flow direction.6 cl, 14 dwg |
