Title (EN) FLUID FILTER HAVING A VALVE UNIT
(FR) FILTRE À FLUIDE DOTÉ D'UN ENSEMBLE SOUPAPE
(DE) FLUIDFILTER MIT EINER VENTILEINHEIT
Abstract:
(EN) The invention relates to a fluid filter (1) having a housing (2) having a fluid inlet (21) and a fluid outlet (22), having a central standpipe (4) forming the fluid outlet (22), having a filter insert (3) placed on the standpipe (4), and having a valve unit (5), wherein the fluid filter (1) can be attached in a sealing manner to a connection flange (6) having a threaded connection (64) and having a sealing surface (60) which is radially separate therefrom. According to the invention, the fluid filter (1) is characterized in that the valve unit (5) has, in the basic form thereof, a circular ring disc-shaped valve plate (50) having at least one decentralized valve opening (51', 51") and that the valve plate (50) is arranged in a sealing manner on the outer circumference of the standpipe (4), movable in the axial direction thereof.
(FR) L'invention concerne un filtre à fluide (1) comprenant un boîtier (2) qui présente une entrée de fluide (12) et une sortie de fluide (22), un tube vertical central, qui forme la sortie de fluide (22), une cartouche filtrante (3) emmanchée sur le tube vertical (4), et un ensemble soupape (5), ledit filtre à fluide (1) pouvant se monter de manière étanche sur une bride de raccordement (6) pourvue d'un raccord fileté (64) et d'une surface d'étanchéité (60) séparée radialement dudit raccord fileté. Le filtre à fluide (1) selon l'invention est caractérisé en ce que l'ensemble soupape (5) comprend un siège de soupape (50) présentant une forme générale de rondelle annulaire, pourvue d'au moins une ouverture de soupape (51' 51'') excentrée, et en ce que le siège de soupape (50) est monté de manière étanche à coulissement sur le pourtour extérieur du tube vertical (4).
(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 Stand-rohr (4), mit einem auf das Standrohr (4) aufgesteckten Filtereinsatz (3) und mit einer Ventileinheit (5), wobei der Fluidfilter (1) dichtend an einen Anschlussflansch (6) mit einem Gewindeanschluss (64) und mit einer davon radial getrennten Dichtfläche (60) anbaubar ist. Der Fluidfilter (1) gemäß Erfindung ist dadurch gekennzeichnet, dass die Ventileinheit (5) eine in ihrer Grundform kreisringscheibenförmige Ventilplatte (50) mit wenigstens einer dezentralen Ventilöffnung (51', 51") aufweist und dass die Ventilplatte (50) auf dem Außenumfang des Standrohrs (4) in dessen Axialrichtung verschieblich dichtend angeordnet ist.
