FIELD: mechanics. ^ SUBSTANCE: said device incorporates a diffuser, a course installed over the diffuser on a device, which provides for the course rotation around the vertical axis, and a cowl. At one end of the course, a weather cock perpendicular to the course tangent line is rigidly attached. To the course other end, a deflector is rigidly attached at an acute angle to the course tangent line. To the axis, vanes located inside the diffuser are rigidly attached. Over them, in pairs, brackets with rigidly attached air traps are attached to the axis at a distance not less than an air trap height. ^ EFFECT: simplified design of the device. ^ 2 dwg |
