The fume-extraction flap opening and closing mechanism of the present invention has a vertically positioned fixed beam with its upper end provided with yoke and in pivot joint with one end of a tie rod that is connected with the clamping ring of the lower end of servo actuator, whereas the lower end of the beam is in pivot joint with one end of the lever the other end of which is in pivot joint with the end of said servo actuator. The upper end of the vertical beam mounts the fixed part of a lock, which has its movable part connected, together with the end of the actuator rod, with one end of movable connector the other end of which is in pivot joint with holder fixed to the frame of fume-extraction flap. Moreover, said mechanism is provided with at least one blocking cord with one end connected to the holder fixed to the frame of fume- extraction flap and the other end connected with the holder of roof port frame. Preferably, the upper face of vertical beam has a slant surface provided with a yoke that serves as the tie rod holder. Also favorably, the movable part of the lock is provided with tensioning spring. It is also favorable that the other end of the lever be provided with servo actuator holder having a profiled end and the other end of the tie rod be provided with the holder of the actuator clamping ring having a side profile cutout of similar shape to that of the actuator holder end.
