Abstract[English]
A filter housing 1 for housing a filter element (10) for filtering a liquid, for example water, with two housings (2, 5), which each have inner and outer tube sections (21, 51, 30, 61) extending in a longitudinal direction, which can each be inserted telescopically into one another, is disclosed. This results in the formation of an inner flow channel (48) and of at least one outer flow channel (40, 44), which are separated from one another and sealed respectively against the central interior space (10d) of the filter element (10). The filter housing is characterized by a simple and cost-effective structure, which can facilitate the installation of filter cartridges of different lengths and, after installation in a filter cartridge for filtering a liquid, for example water, ensures the formation of suitable flow conditions therein.[French]
Est divulgué un boîtier de filtre (1) pour loger un élément filtrant (10) pour filtrer un liquide, par exemple de l'eau, avec deux boîtiers (2, 5), qui présentent chacun des sections de tube interne et externe (21, 51, 30, 61) s'étendant dans un sens longitudinal, qui peuvent chacune être insérées de manière télescopique l'une dans l'autre. Il en résulte la formation d'un canal d'écoulement interne (48) et d'au moins un canal d'écoulement externe (40, 44), qui sont séparés l'un de l'autre et étanchéifiés respectivement contre l'espace intérieur central (10d) de l'élément filtrant (10). Le boîtier de filtre est caractérisé par une structure simple et économique, qui peut faciliter l'installation de cartouches filtrantes de différentes longueurs et, après installation dans une cartouche filtrante pour filtrer un liquide, par exemple de l'eau, assure la formation de conditions d'écoulement appropriées à l'intérieur de celui-ci.
