Abstract (en)
A Fire damper composed of the body where division is self-aligning fixed against the axis division of the closing spring device ( 2 ) and releasing fuse link element ( 3 ) are placed inside the body ( 5 ) in the plane perpendicular to the axis ( 1 ) where the division is fixed on ( 6 ), and besides, there is a flexible sealing ring ( 11 ) fixed on the notch made in the circumference of the division ( 6 ) that works closely with thermal expanding gasket ( 12 ) located inside on the body wall ( 5 ) in lateral plane corresponding to the position of the division ( 6 ) in the closed position. There can also be at least two rows of lengthwise holes ( 13 ) on the body wall ( 5 ) in lateral plane corresponding to the position of the division ( 6 ) in the closed position, protecting against heat conduction along the vent duct walls. Additional feature is the fact that there are limit switches ( 8 ) and ( 9 ) placed inside the body ( 5 ), monitoring division's position ( 6 ). The nipple or sleeve make allows for easier cut off flap valve mounting in the vent or air-conditioning installation.
