Title (EN) DEVICE FOR DAMPING PRESSURE VARIATIONS IN A SEALED CHAMBER
(FR) DISPOSITIF D'AMORTISSEMENT DE VARIATION DE PRESSION DANS UNE ENCEINTE FERMEE
Abstract:
(EN) 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.
(FR) La présente invention concerne un dispositif (1) pour l'amortissement de variation de pression dans une enceinte fermée comprenant : un élément plan maintenu fixe (4) dans l'enceinte fermée et perforé d'au moins un orifice (10); au moins un élément plan mobile (3) disposé, en fonctionnement normal, dans le même plan commun que l'élément maintenu fixe de l'enceinte de façon à recouvrir l'orifice de l'élément maintenu fixe, ledit élément plan mobile étant apte à s'écarter de l'orifice en direction du sommet ou du fond de l'enceinte et en particulier les dimensions dudit élément maintenu fixe étant au moins égales à celles de l'orifice de l'élément maintenu fixe, de préférence égales à celles dudit orifice; au moins un organe de rattachement (7) rendant l'élément mobile solidaire de l'élément maintenu fixe et permettant le maintien, l'écartement ou le rappel de l'élément plan mobile par rapport à l'orifice de l'élément maintenu fixe, en particulier ledit organe de rattachement comporte une tige (8) entourée d'au moins un ressort (9) de torsion ou de compression, et une utilisation de ce dispositif.
