Abstract (en)
A hot gas and fume venting device comprising a shutter (1) that is pivoted about a horizontal axis (A) to close a skylight-like opening (3), including a supporting beam (4), which is fixed across the opening (3) at right angles to the pivoting axis, and a telescopic jack (6), in which the outer cylinder is articulated to the beam (4) about an axis that lies parallel to the pivoting axis (A) and the innermost cylinder is articulately coupled to a point of the shutter; the jack (6) is positively extendable by means of compressed gas contained in a bottle (39) that is controlled by a smoke and/or hot gas sensor (40) to rotate the shutter (1) from a closed position into an open position, and the jack (6) is provided with a hydraulic shock absorber to allow the controlled descent of the shutter beyond the 90<o> opening position until it reaches the stop position. <IMAGE>
