Abstract (en)
[origin: EP1359326A1] The present invention relates to a centrifugal drive device for automatic opening of fan louvers (7), among those commonly used for ventilating large hangars, such as those intended for raising animals. This device has a special design based on the use of inertial masses (3.4.1) that exert in their rotation motion a centrifugal force transmitter by cranks (3.4) to an axially displaceable plate (3.2). This second plate is guided and by means of a rod (4) which by means of a rod that is disengaged from the rotation motion by a bearing pushes (3.2.2) the central louver, which in turn with a common guide opens all the remaining louvers.
