The invention concerns a device for controlling revolving door leaves for passage with access control, comprising at least one door leaf (1d), (1g) revolving between a position clearing said passage (2) and a position closing this passage, reading, sensing and controlling means (5 to 8) for authorising passage access to users, and members (9 to 11) for controlling the revolving of said door leaf (1d, 1g) between said positions, these members being controlled by said means (5 to 8). Said control members comprise at least one air cylinder (12d, 12g) supplied by a compressed air reserve (10) connected to a compressor (9), which is coupled with an electric motor. An irreversible mechanism prevents the doors from being forcefully opened, except by the action of the cylinders. |
