Abstract

PURPOSE: To prevent the damage of the device by slowly closing a damper used in an air conditioning and exhaust duct by the restoring momentum of a return spring through a speed reducing gear of a DC geared motor when the duct is unused or when a fire occurs.
CONSTITUTION: When a power source switch is turned ON upon using no damper, a predetermined DC voltage is applied to a solenoid through a transformer 12 and a rectifying circuit 13. By this operation, a brush 10 is urged against the commutator face of a DC geared motor 1 through an arm rod 9. By this operation, the motor 1 is rotated and the damper 4 is opened until a cam 3 turns OFF a limit switch 11. Then, the switch 16 is turned OFF upon using no duct, the solenoid 7 is deenergized, and the brush 10 separates from the commutator face 6, whereby the damper 4 slowly rotates reversely by the restoring momentum of the return spring on the damper shaft through the speed reducing gear, and the damper is closed.
