Title
(EN) A FILTER ELEMENT ASSEMBLY
(FR) ENSEMBLE ÉLÉMENT FILTRANT
Abstract
(EN)
A filter element assembly is disclosed which comprises a filtration media and an end fitting (154, 200) through which a sealing connection is made between the filter element assembly and a housing (100) so that, when the sealing connection is made, the end fitting (154, 200) defines in part a flow path for fluid between the housing (100) and the filtration media, in which the end fitting (154, 200) has first (200) and second (154) parts which can be separated axially, the filter media extending axially away from the second part (154) in a direction away from the first part (200), each of the first and second parts having an outer wall (204, 160) with an external cylindrical surface which is threaded (212, 158), and in which each of the first and second parts (200, 154) has an axially facing edge surface which faces the other of the first and second parts, the facing edge surfaces being shaped to define a pre-determined relative rotational alignment of the first and second parts (200, 154) in which the first and second parts fit together so that the threads (212, 158) on the external surfaces of the first and second parts (200, 154) form a continuous thread.
(FR)
L'invention concerne un ensemble élément filtrant qui comprend un milieu filtrant et un raccord d'extrémité (154, 200) à travers lequel une liaison d'étanchéité est réalisée entre l'ensemble élément filtrant et un boîtier de telle sorte que, lorsque la connexion d'étanchéité est réalisée, le raccord d'extrémité (154, 200) définit en partie un chemin d'écoulement pour le fluide entre le boîtier (100) et le milieu filtrant, dans lequel le raccord d'extrémité (154, 200) a des première (200) et seconde (154) parties qui peuvent être séparées axialement, le milieu filtrant s'étendant axialement à l'opposé de la seconde partie (154) dans une direction s'éloignant de la première partie (200), chacune des première et seconde parties ayant une paroi externe (204, 160) ayant une surface cylindrique externe qui est filetée (212, 158), et dans lequel chacune des première et seconde parties (200, 154) a une surface de bord orientée axialement qui fait face à l'autre des première et seconde parties, les surfaces de bord opposées étant formées pour définir un alignement rotatif relatif prédéterminé des première et seconde parties (200, 154) dans laquelle les première et seconde parties s'adaptent l'une à l'autre de telle sorte que les fils (212, 158) sur les surfaces externes des première et seconde parties (200, 154) forment un fil continu.
