摘要:
The invention relates to a filter (12) for filtering a medium, in particular an aqueous urea solution to be filtered. The filter (12) has a filter element (18) with a filter material (30). The medium can be pumped at least partly, preferably completely, out of the filter (12) without passing the filter material (30) such that dirt filtered out of the medium is not released from the filter material (30) and pumped out together with the medium. For this purpose, the filter (12), in particular the filter element (18), is provided with a non-return element (36) such that a flow of the medium from the unfiltered side (32) to the clean side (34) of the filter (12) is blocked but a flow of the medium from the clean side (34) to the unfiltered side (32) of the filter (12) is possible. The non-return element (36) is preferably designed in the form of a mushroom-shaped membrane (42). The membrane (42) is additionally anchored in a continuous recess (46) of the filter (12) preferably by a thickened portion (48) in the base part of the mushroom shape. The head part of the mushroom shape covers preferably at least one through-recess (38, 40) of the filter (12) for the flow of the medium from the clean side (34) to the unfiltered side (32).

The invention relates to an interchangeable filter element for fixed installation in the oil circuit, in particular of a motor vehicle. The interchangeable filter element comprises a filter housing (1) with a front wall (2) where a peripheral seal ring (3) is disposed, said seal ring having a contact surface (4). Fastened at the front wall (2) is a central connection nozzle (6). A peripheral seal lip (5) is formed in one piece on the seal ring (3) radially inside of the contact surface (4) thereof, said seal lip lying against a sealing surface (7) of the connection nozzle (6) in a sealing fashion.

The invention relates to a filter element (10) for purifying a fluid. The filter element (10) has at least one upper end disc (11) and a lower end disc (12), which consist of plastic. A filter medium (18) extends between the end discs (11, 12). The filter medium (18) is fixed in the end discs (11, 12) by a sealing compound (19). A nonwoven ring (17) is located in the end discs (11, 12) and is permanently connected to the latter (11, 12). The sealing compound (19) at least partially penetrates the nonwoven ring (17), forming a sealed, permanent connection between the end disc (11, 12) and the sealing compound (19).

Die Erfindung betrifft ein Entnahmesystem (10), umfassend ein Abscheideelement (12) zum Abscheiden von in einem Fluid enthaltenen Verunreinigungen mit einem Abscheidemedium (18) und mit einer stirnseitig am Abscheideelement (12) angeordneten Endscheibe (20) mit einer zentralen Ausnehmung (22) sowie eine Entnahmehilfe (14) zum Entnehmen des Abscheideelements (12) aus einem Gehäuse (16). Die Entnahmehilfe (14) weist einen Griffabschnitt (26) und wenigstens zwei Rastfinger (34) auf, wobei sich die Rastfinger (34) entlang einer Mittelachse (36) der Entnahmehilfe (14) vom Griffabschnitt weg erstrecken, und wobei an jedem Rastfinger (34) ein Hakenelement (38) angeordnet ist, das erfindungsgemäß zum Hintergreifen der Endscheibe (20) des Abscheideelements (12) radial außerhalb eines die zentrale Ausnehmung (22) in radialer Richtung nach außen unmittelbar begrenzenden Endscheibenbereichs (20a) dient. Die Erfindung betrifft darüber hinaus eine Entnahmehilfe (14) für ein solches Entnahmesystem (10).
摘要:
A plate-type filter element has a filter-medium body and a seal surrounding the filter-medium body, said seal fitting sealingly against a first sealing surface that is on the filter housing side and that extends on a filter-element plane, a sealing handle, designed to fit sealingly against a second sealing surface on the filter housing side, being connected to the surrounding seal, said second sealing surface extending at least partially outside the filter element plane.
