Title (EN) FLUIDFILTER COMPRISING A HOUSING AND A CENTRAL VERTICAL PIPE THAT FORMS A FLUID OUTLET
(FR) FILTRE À FLUIDE COMPRENANT UN BOÎTIER ET UN MONTANT TUBULAIRE CENTRAL FORMANT UNE ÉVACUATION DE FLUIDE
(DE) FLUIDFILTER MIT EINEM GEHÄUSE UND EINEM EINEN FLUIDABLAUF BILDENDEN ZENTRALEN STANDROHR
Abstract:
(EN) The invention relates to a fluid filter (1) comprising: a housing (2) with a fluid inlet (21) and a fluid outlet (22); a central vertical pipe (4) that forms the fluid outlet (22); a filter cartridge pushed onto the vertical pipe (4); and a valve unit (5). The vertical pipe (4) has a screw thread (43, 44) on each axial end region (41, 42), for connection to the housing (2) on one side and to a filter connection flange (5) on the other side, and at least one passage (48) in the region (40) lying between the end regions. A fluid filter (1) according to the invention is characterised in that the vertical pipe (4) has, on the outer periphery of the region (40) lying between the axial end regions (41, 42), guide elements (45) for at least one valve body (55) of the valve unit (5) and/or guide elements and retaining elements (46) for a valve spring support (56) of the valve unit (5). Alternative fluid filters (1) according to the invention are disclosed in the parallel claims.
(FR) L'invention concerne un filtre à fluide (1) comprenant un boîtier (2) présentant une arrivée de fluide (21) et une évacuation de fluide (22), un montant tubulaire (4) central formant l'évacuation de fluide (22), une garniture de filtre emboîtée sur le montant tubulaire (4) et un ensemble soupape (5), le montant tubulaire (4) comprenant sur ses zones d'extrémité axiale (41, 42) respectivement un filet de vis (43, 44) destiné à être relié d'une part au boîtier (2) et d'autre part à une bride de raccordement (5) de filtre et présentant dans sa zone (40) située entre ces derniers au moins une ouverture de passage (48). Un filtre à fluide (1) selon l'invention est caractérisé en ce que le montant tubulaire (4) comprend dans sa zone (40) située entre les zones d'extrémité axiales (41, 42) sur la périphérie extérieure des éléments de guidage (45) pour au moins un corps (55) de soupape de l'ensemble soupape (5) et/ou des éléments de guidage et de retenue (46) pour un appui élastique (56) de l'ensemble soupape (5). D'autres filtres à fluide (1) selon l'invention sont indiqués dans les revendications indépendantes.
(DE) Die 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 und mit einer Ventileinheit (5), wobei das Standrohr (4) an seinen axialen Endbereichen (41, 42) jeweils ein Schraubgewinde (43, 44) zur Verbindung einerseits mit dem Gehäuse (2) und andererseits mit einem Filteranschlussflansch (5) und in seinem dazwischen liegenden Bereich (40) wenigstens eine Durchlassöffnung (48) aufweist. Ein Fluidfilter (1) gemäß Erfindung ist dadurch gekennzeichnet, dass das Standrohr (4)in seinem zwischen den axialen Endbereichen (41, 42) liegenden Bereich (40) auf dem Außenumfang Führungselemente (45) für wenigstens einen Ventilkörper (55) der Ventileinheit (5) und/oder Führungs-und Halteelemente (46) für eine Ventilfederstütze (56) der Ventileinheit (5) aufweist. weitere erfindungsgemäße Fluidfilter (1) sind in den nebengeordneten Ansprüchen angegeben.
