Abstract: A cover for a filter system for filtering a fluid has a fluid channel arranged at an inner side of the cover. The cover has a rim and at least one opening arranged in the rim to allow the fluid to pass through, wherein the opening is connected in fluid communication with the fluid channel. The fluid channel is connected in fluid communication with the interior of a filter element of the filter system. A seal for the cover has a first sealing ring and a second sealing connected to each other by flanks. The filter system has a housing with a housing part that is closable by the cover. A filter element is exchangeably arranged in the housing, and the fluid channel of the cover is connected in fluid communication to the interior of the filter element.

Abstract: A filter element has a filter medium body with a first side and an oppositely positioned second side. A first sealing or supporting element is arranged at the first side. A second sealing or supporting element is arranged at the second side. The first side is positioned in a plane. The second side has a first section and a second section, wherein the first section has a first spacing relative to the first side and the second section has a second spacing relative to the first side, wherein the first and second spacings are different. One of the first and second sides is the inflow side of the filter medium body and the other one of the first and second sides is the outflow side of the filter medium body.

Abstract: A filter element is provided with a filter bellows that has an inflow side and an outflow side for a fluid to be filtered, wherein the filter bellows is made of a zigzag-folded filter medium with folds with fold edges. The inflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the inflow side and the outflow side is defined by the fold edges of the folds of the zigzag-folded filter medium at the outflow side. At least one filter element holding device is provided that holds the filter element in a filter housing. The at least one filter element holding device is connected directly or indirectly with the filter bellows. At least one supporting element supports the filter element in the filter housing; the at least one supporting element is separate from the at least one filter element holding device.

Abstract: A round filter element is provided with an elongate filter medium body with a wall structure flowed through by a fluid to be purified in a flow direction radially relative to a longitudinal axis of the filter medium body. A seal support for a sealing element is arranged adjacent to a radially outwardly positioned outer wall of the wall structure of the filter medium body and adjacent to an end face of the filter medium body. The seal support has across a major portion of its circumference a constant radial spacing relative to the outer wall of the wall structure of the filter medium body. The seal support has at least one radially inwardly oriented indentation located at a longitudinal side of the filter medium body and provided with a reduced radial spacing relative to the outer wall of the wall structure of the filter medium body.

Abstract: A secondary element with a first open end and a second end positioned opposite the first end has a filter medium arranged about a longitudinal axis of the secondary element and extending from the first open end to the second end. A closed end disc is disposed at the second end and seal-tightly closes off the second end. The closed end disc has a first connecting element that, for an intended installation of the secondary element in a filter system, is configured to interact with a second connecting element of a support tube of the filter system to secure the secondary element on the support tube. A filter system with such a secondary element has a support tube provided with a complementary second connecting element, wherein the secondary element is secured on the support tube by the first and second connecting elements engaging each other.

Abstract: A filter housing (11) has at least one inlet (15) and at least one outlet (17) for the fluid. The filter element (10) includes a filter body of a filter medium (18).The filter element (10) is configured to be arranged in a filter housing (11) separating the at least one inlet (15) from the at least one outlet (17). An element axis (14) of the filter element (10) and a housing axis (25) of the filter housing (11) can be aligned parallel or axially to an installation direction (12) of the filter element into the filter housing. The filter element (10) may include at least one guide crosspiece (46, 48) which extends axially and radially outward on a peripheral exterior side (26), relative to the element axis (14), of the filter element (10). The filter element (10) has at least one seal (42) running peripherally relative to the element axis (14), the seal (42) having a seal line with at least one convexity (54) arranged peripherally between two corner regions of the filter element (10) and is separated by these corner regions.
