A centrifugal regulator device for opening and closing the pivoted-vane shutter associated with an electric fan unit has an actuator member (56) connected to a base element (46) by means of at least two pivoted arms (52,54) each including a centrifugal mass (63) and cooperating, in the fully open position of the vanes (12), with mechanical end-stop members (88). The actuator member (56) is guided for translational movement by appendages (86) provided with apertures for slidingly coupling with corresponding guide rods (84) fixed to the base element (46) and extending parallel to and spaced from the axis of rotation of the fan of the electric fan unit. <IMAGE> |
