The invention relates to a ventilating device (1), which is configured inside a housing of at least one ventilating channel (32 or 33) that disposes of a closing device (5 or 6) for adjusting different air intake and air discharge positions. The invention provides that the closing device (5, 6) is comprised of two coaxially extending cylindrical tube sections (12, 13) that are placed one inside the other and whose lateral surfaces are provided with openings (14, 17, 18, 19, 20, 21), which are distributed over the periphery and which can be brought into a position in which they overlap, whereby the outer tube section (12) assumes the positioning of the inner tube section (13) that is accommodated therein in a manner that permits it to rotate. |
