<p>A central body (11) holds radially mounted blades (12) to direct the flow of air from the outside towards the radiator. The end of each blade inside the body consists of a pivot pin (31) with cylindrical toothing (31a) and is mounted on the body by bearings (31b) so that each blade can rotate about its longitudinal axis. Each gearing is coupled to an actuator consisting of a rectilinear rack (41a) with a tube (41) mounted on a shaft (21a) with which it rotates. The actuators are driven by a motor (43) through a disc (42).</p> |
