Abstract:
The invention relates to a fluid filter (1) which can be mounted on a connection flange (4) having a central stand pipe (40), wherein the fluid filter (1) has an exchangeable filter insert (3) with a hollow cylindrical filter material body (30) encased on the end faces by two end plates (31) and mountable on the stand pipe (40), and wherein the fluid filter (1) has a cup-shaped screw housing (2), which has a screw thread in the center of its base, can be screwed to a mating thread applied on a free end of the stand pipe (40), and supports a seal (22) on the free edge (20) thereof, by means of which the screw housing (2) can be sealed against a sealing surface (45) of the connection flange (4) in the mounted state. The fluid filter (1) according to the invention is characterized in that the filter insert (3) has first centering means (33, 34.1, 36) on the end face area thereof facing the connection flange (4) in the installed state for centering the end face area relative to the connection flange (4) and in that the filter insert (3) has second centering means (34, 34.2) on the outer periphery of the end face area thereof facing the connection flange (4) in the installed state for centering the free edge (20) of the screw housing (2) relative to the sealing surface (45) of the connection flange (4), wherein the second centering means (34, 34.2) interact in a centering manner with the free edge (20) of the screw housing (2) in the installed state. In addition, the invention relates to a filter insert (3) for use in a fluid filter (1) of the previously described type.
Abstract:
A filter arrangement for threadably securing to a filter head includes a housing having a surrounding wall defining an interior volume, an open mouth providing access to the interior volume and an end opposite of the open mouth. The surrounding wall has an exterior and an interior. A filter media construction is operably held within the interior volume. A sleeve, distinct from the housing, is secured to the exterior of the surrounding wall adjacent to the housing mouth and extending partially along the surrounding wall. The sleeve has an exterior and an interior. The exterior of the sleeve defines mounting threads constructed and arranged to removable mount with the filter head, when the filter arrangement is secured to the filter head. The interior of the sleeve is against the exterior of the surrounding wall. A first seal member is oriented against the sleeve to create a seal with a filter head, when the filter arrangement is secured to the filter head. A filter assembly includes a filter arrangement and a filter head. The filter arrangement is removably secured to the filter head by a threaded connection between the sleeve and the filter head. A system includes an engine utilizing a liquid and a filter assembly in fluid communication with the engine to filter the liquid. Methods of making filter arrangements include utilizing structures characterized above.
Abstract:
The present invention aims to provide an adsorption carrier-packed column which enables reduction of bypassing, and improvement of the performance of the adsorption carrier. The present invention provides an adsorption carrier-packed column comprising a central pipe, adsorption carrier, plate A, and plate B, wherein an insertion material C is inserted between the adsorption carrier and the plate A; an insertion material D is inserted between the adsorption carrier and the plate B; the ratio of the deformation rate of the insertion material C (C 1 ) to the deformation rate of the adsorption carrier (E 0 ) is 1≤C 1 /E 0 ≤10, and the ratio of the deformation rate of the insertion material D (D 1 ) to the deformation rate of the adsorption carrier (E 0 ) is 1≤D 1 /E 0 ≤10; and the ratio of the thickness of the insertion material C (T C ) to the distance of a gap between the adsorption carrier and the plate A (L A ) is 1.1≤T C /L A ≤4, and the ratio of the thickness of the insertion material D (T D ) to the distance of a gap between the adsorption carrier and the plate B (L B ) is 1.1≤T D /L B ≤4.
Abstract:
A filter device, comprising at least one first connection (A1) to a hydraulic working circuit, with which a filter element (F1) is associated, and comprising at least one additional connection (A2), by means of which leakage oil amounts of hydraulic components can be fed, is characterised in that a control apparatus (V2) is provided, by means of which the leakage oil amounts can be fed from the additional connection (A2) to the filter element (F1) when a specified working pressure of the working circuit is not reached at the first connection (A1).
Abstract:
A filter cartridge (30) for filtering fuel, comprising a filter wall (31) having a tubular shape, a first support plate (32) fixed to an end of the filter wall (31) and a second support plate (33) fixed to the opposite end of the filter wall, each support plate (32, 33) defining a respective portion (324,325;335,336) of a discharge conduit (324,325; 50; 335,336) of the water which separates from the fuel during filtration of the fuel; the peculiarity of the invention consists in the fact that it comprises a connecting cannula (50) able to connect the portions (324,325;335,336) and arranged externally of the filter wall (31).
