Abstract
PURPOSE:To enable shifting rapidly operating conditions to open or closed status in simple construction by arranging to interlock a mechanical rotation means to an electric rotation means in the same direction in a rapid manner and maintain a damper blade in either open or closed state. CONSTITUTION:When an attempt is made to pass electricity to a first rotary solenoid 8 of a first electric rotation means and rotate a damper blade 3 in opening direction, a supporting crank 13 is adapted to interlock so that energized force of a spring 15 may prompt the rotation of the first rotary solenoid immediately when the supporting crank exceeds a vertical position. This mechanical rotation means prompts the damper blade 3 to rotate rapidly in opening direction and accelerate the rotation secondarily in the same direction and maintains the damper blade 3 in opening status at once without stopping the damper blade 3 at an intermediate position. Furthermore, this apparatus makes it possible to carry out the above operation in reverse motion by passing electricity to a rotary solenoid 11, which is a second rotation means when shifting the operation to closed state.
