The invention concerns a flow regulator, which ensures a consistent adjustable airflow in a ventilation shaft (1). For this, a swingable control flap (4), with a forward direct flow part (5) and a more distant similarly shaped direct flow part (6), is situated on a diametrical swivel axle (3) in the ventilation shaft, whilst a bellows (23) is arranged between the lee side of the control flap and the control flap's more distant direct flow part and a base plate (9), whereby the bellows internally communicates with the direct flow side via a hatch (24) in the bellows and the more distant direct flow part (6). The invention is designed so that, the swingable base plate (9) is appointed on the aforementioned swing axle, or a bushing (8), and is adjustable with the help of a positioning rod (10) connected to an outer positioning motor (14), along with a flat spring, (18) which extends between the base plate's (9) free end and the lee side of the forward direct flow part (5), whereby a positioning control (10) arranged on the positioning rod (17) is designed to regulate the flat spring in the desired direction.<IMAGE> |
