Device for directing air flow in the air duct

Abstract

The device to control air flow direction in the air duct according to the invention, which has an air duct and is provided with a working machine in the form of a fan or turbine, is characterized by a working machine that is located in the profiled damper (3). This is a profiled single plane rotary baffle, in which there is a central hole and two embossings forming two canopies: the suction/inlet canopy (3a) and the compression/outlet canopy (3b), arranged in such a way that they are located on opposite sides of the plane of the baffle, while the canopies (3a), (3b) have the shape of the rotary bodies with a common axis of rotation coinciding with the axis of rotation of the profiled damper (3), and are so interposed that the central hole is in the plane perpendicular to the plane of the profiled damper (3), and perpendicular to the axis of rotation of the profiled damper (3). The profiled damper (3) rotates pendulously at an angle of no more than 180 degrees, and in extreme positions, through contact of the edge (4) to the partition/sealing shelf (2), separates the upper part (1a) from the lower part (1b) of the air duct (I). With the angle of rotation of no more than 180 degrees, the position of the canopies (3a, 3b), relative to the air duct (1), changes so that the canopy that was in the upper part of the air duct is moved to its lower part and the canopy that was in the lower part of the air duct (1) is moved to its upper part.
