(54) Fire damper


(57) 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.
