Abstract (en)
[origin: WO2010076544A1] The present invention relates to a device (1) for damping pressure variations in a sealed chamber, including: a flat element (4) held stationary in the sealed chamber and perforated with at least one opening (10); at least one flat mobile element (3) arranged, in normal operation, in the same shared plane as the element held stationary in the chamber so as to cover the opening of the element which is held stationary, said mobile flat element being suitable for separating from the opening in the direction of the top or the bottom of the chamber, the dimensions of said element which is held stationary being at least equal to those of the opening for the element which is held stationary, preferably equal to those of said opening; at least one joining member (7) rigidly connecting the mobile element to the element which is held stationary and enabling the flat mobile element to be held, separated or returned relative to the opening of the element which is held stationary, in particular said joining member comprising a rod (8) surrounded by at least one torsion or compression spring (9). The invention further relates to a use of said device.
