Title (EN) FILTER DISC ASSEMBLY AND FILTER DISC CAPSULES
(FR) ENSEMBLE FILTRE CIRCULAIRE ET CAPSULES A FILTRES CIRCULAIRES
Abstract:
(EN) Known filter capsules are constructed of two annular discs of filter material which are assembled onto the outward surfaces of two respective support discs. The discs of filter material are secured onto the support disc by a swaged ring collar which clamps the discs of filter material and the support discs together forming a bi-laminate assembly. As a result of the support discs being cut from a sheet which is formed with a plurality of holes, the radially innermost face and radially outermost face of the respective support discs includes some sections of the surfaces which define some of the holes, and the respective support disc faces do not, therefore, have a smooth surface. The present invention provides an annular filter cell assembly (1) comprising a circular support disc (2) formed with a central aperture (4) defined by a smooth radially innermost surface (6), a circular filter element (8) and an annular ring (12), the arrangement being such that the filter element (8) is held between the support disc (2) and the annular ring (12) and the radially innermost surface (6) of the support disc (2) is bonded to the radially innermost surface of the annular ring (12) such that the filter cell assembly (1) defines a common axial through port (15).
(FR) Les capsules à filtres existantes sont constituées de deux disques de matière filtre qui sont assemblés sur les surfaces externes de deux disques support indépendants. Les disques de matière filtre sont fixés sur le disque support au moyen d'un collier annulaire embouti fixant ensemble les disques de matière filtre et les disques support qui forment ainsi un ensemble constitué de deux couches. Etant donné que les disques support sont découpés dans une feuille contenant une pluralité de trous, la surface la plus proche du centre et la surface la plus à éloignée du centre de chacun des disques support comportent des parties qui définissent quelques uns des trous, les surfaces de chacun des disques support ne sont donc pas lisses. La présente invention concerne un ensemble cellule à filtres annulaires (1), comportant un disque support (2) doté d'un orifice central (4) et défini par une surface lisse située au plus près du centre du disque (6); un élément filtre circulaire (8) et un anneau (12), la disposition étant telle que l'élément filtre (8) est maintenu entre le disque support (2) et l'anneau (12). La surface la plus éloignée du centre (6) du disque support (2) est fixée à la surface la plus proche du centre de l'anneau (12) de telle manière que l'ensemble cellule à filtre (1) définisse un orifice transversal axial commun (15).
