Des éléments de filtre de ce type sont montés entre autres dans des systèmes d'alimentation en carburant de lanceurs et de systèmes orbitaux de transport En plus de l'intérêt d'éliminer des canalisations les impuretés non positioned flat, in particular for mounting in fuel supply systems for spacecraft, which consists of a metal filter fabric held in a frame. Filter elements of this type are mounted among other things in launchers' fuel supply systems and orbital transport systems. In addition to the interest of eliminating non-impurities from pipelines.

L'invention a pour objet de constituer un élé- ment de filtre du type mentionné au début de telle façon under the influence of weightlessness or parasitic accelerations. The object of the invention is to constitute a filter element of the type mentioned at the beginning in such a way
