A DEVICE FOR CONTROLLING AND CLOSING GAS FLOWS

摘要

A device intended for controlling and closing gas flows in air-conditioning plants, the device having several parallel control dampers (1, 8) interconnected by means of a lever system (3), the position of the dampers shifting from the first closed position (9) via the open position (10) to the second closed position (11), in total over angle A + B, and that the control dampers open in relation to one another in a phase difference.
