Abstract
A ventilation device (24) for a cooling module (22) of a motor vehicle (10) comprises a tangential flow turbomachine (28-1; 28-2) with an impeller wheel (32-1; 32-2), a frame (30) forming a recess (30-1; 30-2) for receiving the impeller wheel (32-1; 32-2), flaps (52-1; 52-2) which pivot relative to the frame (30), the flaps (52-1; 52-2) being suitable for selectively closing off an opening (51-1; 51-2) through the frame (30). An actuator (54-1; 54-2) for controlling the pivoting of the flaps (52-1; 52-2) comprises an electric motor (56-1; 56-2), the output shaft of which rotates one of the flaps (52-1; 52-2) and a rod (58-1) connecting one flap (52-1; 52-2) to the other flaps (52-1; 52-2), such that the rotation of one flap (52-1; 52-2) is transmitted to the other flaps (52-1; 52-2).
