Title (EN) FLUID FILTER WITH A VALVE UNIT
(FR) FILTRE À FLUIDE MUNI D'UN ENSEMBLE SOUPAPE
(DE) FLUIDFILTER MIT EINER VENTILEINHEIT
Abstract:
(EN) The invention relates to a fluid filter (1) with a housing (2), a fluid inlet (21), a fluid outlet (22), a central standpipe (4) which forms the fluid outlet (22), a filter insert (3) which is plugged onto the standpipe (4), and a valve unit (5) which is arranged on the outer circumference of the standpipe (4). The valve unit (5) has a valve seat (50), a valve body (53) which can be moved in the axial direction of the standpipe (4), a valve spring (57) which is guided on the standpipe (4) and biases the valve body (53) in the valve closing direction, and a valve spring support (56) which is attached to the standpipe (4). The fluid filter (1) according to the invention is characterized in that the valve body (53) is made of an elastomer body, and an intermediate valve ring (55) which is guided on the standpipe (4) in an axially movable manner is arranged between the valve spring (57) and the valve body (53).
(FR) L'invention concerne un filtre à fluide (1) comportant un carter (2), une entrée de fluide (21) et une sortie de fluide (22), un tube vertical central (4) formant la sortie de fluide (22), une cartouche filtrante (3) emboîtée sur le tube vertical (4), et un ensemble soupape (5) agencé au niveau de la circonférence extérieure du tube vertical (4). L'ensemble soupape (5) présente un siège de soupape (50), un corps de soupape (53) mobile dans la direction axiale du tube vertical (4), un ressort de soupape (57) guidé sur le tube vertical (4) et soumettant le corps de soupape (53) à une précontrainte dans la direction de fermeture de la soupape, et un élément d'appui (56) pour le ressort de soupape, monté sur le tube vertical (4). Le filtre à fluide (1) selon l'invention est caractérisé en ce que le corps de soupape (53) est formé par un corps élastomère, et en ce qu'une bague intermédiaire de soupape (55) est guidée en coulissement axial sur le tube vertical (4) entre le ressort de soupape (57) et le corps de soupape (53).
(DE) Die vorliegende Erfindung betrifft einen Fluidfilter (1) mit einem Gehäuse (2), mit einem Fluidzulauf (21) und einem Fluidablauf (22), mit einem den Fluidablauf (22) bildenden zentralen Standrohr (4), mit einem auf das Standrohr (4) aufgesteckten Filtereinsatz (3) und mit einer am Außenumfang des Standrohrs (4) angeordneten Ventileinheit (5), wobei die Ventileinheit (5) einen Ventilsitz (50), einen in Axialrichtung des Standrohrs (4) beweglichen Ventilkörper (53), eine auf dem Standrohr (4) geführte, den Ventilkörper (53) in Ventilschließrichtung vorbelastende Ventilfeder (57) und eine am Standrohr (4) angebrachte Ventilfederstütze (56) aufweist. Der Fluidfilter (1) gemäß Erfindung ist dadurch gekennzeichnet, dass der Ventilkörper (53) durch einen Elastomerkörper gebildet ist und dass zwischen der Ventilfeder (57) und dem Ventilkörper (53) ein auf dem Standrohr (4) axial verschiebbar geführter Ventilzwischenring (55) angeordnet ist.
