Abstract
Description
Dispositif d'amortissement entre deux systèmes concentriques.Damping device between two concentric systems.
La présente invention concerne un dispositif permettant d'obtenir une dissipation d'énergie entre deux points d'un système concentrique de transfert de fluides lorsque celuici est soumis à une excitation axiale d'amplitude et de fréquence variables. The present invention relates to a device making it possible to obtain energy dissipation between two points of a concentric fluid transfer system when the latter is subjected to an axial excitation of variable amplitude and frequency.
En général deux tubes concentriques constituant un système de transfert de fluides élaboré sont liés par une pièce de raccordement rigide le plus souvent en forme d'anneau ou de cône
Le dipositif selon l'invention est caractérisé par la liaison des deux tubes concentriques constituée d'une pièce de raccordement circonférencielle dont I'élasticité permet d'amortir les excitations axiales auxquelles les tubes peuvent être soumis.In general, two concentric tubes constituting an elaborate fluid transfer system are linked by a rigid connection piece, most often in the form of a ring or cone.
The device according to the invention is characterized by the connection of the two concentric tubes consisting of a circumferential connection piece whose elasticity makes it possible to dampen the axial excitations to which the tubes can be subjected.
Selon des modes particuliers de réalisation: -L'épaisseur ainsi que la forme de la pièce de raccordement peuvent varier et faire ainsi varier la souplesse du dispositif. According to particular embodiments: the thickness as well as the shape of the connecting piece can vary and thus vary the flexibility of the device.
-Le dispositif peut comporter une seule ou plusieurs pièces de raccordement.-The device can include one or more connecting pieces.
-Chaque pièce du dispositif peut être mono ou multi couche.-Each piece of the device can be mono or multi layer.
-la fixation peut se faire de différentes manières en fonction du matériau utilisé.-The attachment can be done in different ways depending on the material used.
Les dessins annexés illustrent l'invention
La figure 1 représente en coupe le dispositif selon l'inven- tion.The accompanying drawings illustrate the invention
Figure 1 shows in section the device according to the invention.
Les figures 2 et 3 représentent en coupe,des variantes de ce dispositif.Figures 2 and 3 show in section, variants of this device.
En référence à ces dessinssle dispositif comporte un tube intérieur (I) ainsi qu'un tube extérieur (2) reliés entre eux par une pièce de raccordement (3) de forme révolutive, le dispositif peut comporter une seule pièce de raccordement (3) ou plusieurs pièces de raccordement (4) et (5) de différentes formes.With reference to these drawings, the device comprises an inner tube (I) as well as an outer tube (2) connected together by a connecting piece (3) of revolutive shape, the device can comprise a single connecting piece (3) or several connecting pieces (4) and (5) of different shapes.
La pièce de raccordement de forme révolutive comportera en général deux parties arrondies (6) dont le rayon de courbure peut varier en fonction de l'élasticité souhaitée. The revolutive connecting piece will generally have two rounded parts (6) whose radius of curvature can vary depending on the desired elasticity.
Dans la forme de réalisation selon la figure 2 le dispositif comporte une pièce de raccordement multi-couche (7).In the embodiment according to Figure 2 the device comprises a multi-layer connection piece (7).
Cest cette pièce de raccordement qui par sa souplesse permet de dissiper une partie de 1 énergie des vibrations auxquelles le système peut être soumis. It is this connecting piece which, by its flexibility, makes it possible to dissipate part of the energy of the vibrations to which the system may be subjected.
Le dispositif selon l'invention est particulièrement destiné à s'enserrer dans des systèmes concentriques de transfert de fluides qui sont soumis à des contraintes de vibrations que le dispositif dissipera en partie. The device according to the invention is particularly intended to be enclosed in concentric systems for transferring fluids which are subjected to vibration stresses which the device will partially dissipate.
