A pneumatic device for driving double four-leaf doors, essentially consisting of synchronously actuating the two pairs of articulated leaves that form the unit of a door by means of the shank of a pneumatic piston articulated with the radial arm which has one of only two turning axes, of the pair that forms the door; and synchronously transporting this rotation to the lateral articulation axis of the other pair, by means of a cross rod; combining with two chains, which mesh accurately and respectively with respective pinions integral with the respective axes of general rotation of each pair of leaves.
