The guide means includes a guide rail provided on the tank main body and a slider provided on the pump unit. The slider is configured to be slidably engaged with the guide rail.

A cleaning module (10) for cleaning a media flow of a first medium contaminated with a second medium that has a housing (12) having an inlet (18) and an outlet (20, 21) and a replaceable filter element (30) arranged within the housing (12). In this arrangement, a flow direction (32) of the media flow is directed through the filter element (30) in the specified installed state against the force of gravity. The filter element (30) has an absorptive and/or adsorptive material (34) for picking up at least a portion of the second medium in the first medium. A filter element for the cleaning module (10) and a filter system (100) having the cleaning module (10) are disclosed.

The invention relates to a filter unit, a filter system (44b) with at least two filter units, and to a motor vehicle with a filter system (44b). A filter bowl (12d-e) of the filter unit is formed by a base and a cover. Embodied in a side wall of the base are at least two access openings to an antechamber or collection chamber (34a-b) in the filter bowl (12d-e). Embodied integrally with the cover is a collection line segment or supply segment (26d-e) that leads from a clean chamber or an unfiltered side antechamber in the filter bowl (12d-e) to at least two open ends (28l). The inventive filter system (44b) has at least two inventive filter units, and fluid may flow through their filter elements (30, 30a-d), which are switched in parallel. The invention facilitates the space-saving arrangement of filter units and filter systems (44b) in constricted and/or complexly shaped installation spaces, especially in motor vehicles.

A filter assembly for a fluid to be filtered, in particular fuel or oil, has a filter housing having a housing lower part that is configured as a single piece and has at least one fluid inlet for the fluid to be filtered and a plurality of filter pots that are arranged next to one another side by side in a shared plane and are fluidically connected to one another via side wall passages An upper housing part closes the filter pots and has a fluid manifold that has at least one fluid outlet for the filtered fluid flowing out from the filter pots. At least two filter elements, one being arranged in each of the filter pots of the filter housing. The filter assembly is a more inexpensively-manufactured and as configured for installation even in confined installation spaces, so as to accommodate a sufficiently large filter surface for a predetermined volume flow of a fluid to be filtered.

A fuel filter assembly includes a filter housing defining a cavity, a center stack having a base component and a top portion. The center stack is positioned within the cavity of the filter housing and attached to the housing, the center stack having an axial aperture in the top portion, the axial aperture having a circumferential surface, and a fuel filter. The fuel filter includes a filter base, an end cap having a top surface and a bottom surface opposite the top surface, an axial extension that extends from the bottom surface, and at least one prong attached to the axial extension, the at least one prong having an axial surface facing away from the top surface that axially locates the fuel filter in the housing against the circumferential surface, a filter element attached to the bottom surface of the end cap, and a pin attached to a filter base.

A filter structure for fuel fluids, comprising a first filter wall, a coalescing second filter wall located downstream of and in contact with the first filter wall, and a hydro phobic wall, in which the first filter wall comprises a first porous layer, realised in a material having a receding contact angle Θ rec comprised between 30° and 80°; the coalescing second filter wall comprises a second porous layer made of a material having a greater porosity than the first filter wall; the hydrophobic third wall comprises a layer located at a distance from the second layer.

A filter structure (100) for fuel fluids comprising a first filter wall and a hydrophobic wall, characterised in that the hydrophobic wall is made of a material having a mean static angle that is equal to or greater than 90°, a receding contact angle θ.sub.rec that is less than 90° and a hysteresis H, between an advancing contact angle θ.sub.av and a receding contact angle θ.sub.rec, that is comprised between 50° and 80°.

Disclosed is a fuel filter (10) for fuel, in particular diesel fuel, of an internal combustion engine, in particular of a motor vehicle, and to a filter element of such a fuel filter. A housing (12) has at least one fuel inlet (26) for the fuel to be cleaned, at least one fuel outlet (18) for cleaned fuel, and at least one water outlet (30) for water which has been separated from the fuel. The filter element (36) is arranged in the housing (12), said filter element sealingly separating the fuel inlet (26) from the fuel outlet (18). The filter element (36) has a filter medium (38) which is designed as a hollow body and which can be permeated from the inside to the outside or from the outside to the inside in order to filter the fuel. The filter element (36) has a coalescing medium (58) designed as a hollow body for separating water contained in the fuel. The coalescing medium (58) is arranged downstream of the filter medium (38) in the flow path (78) of the fuel, around said filter medium, or in the interior (45) delimited by the filter medium. The coalescing medium (58) includes at least one regenerated-fiber coalescing system consisting of a coalescing material (60) which is suitable for coalescing water and which has at least 20 wt. % of regenerated fibers, preferably at least 50 wt. %.
