摘要:
A filter insert piece comprises a filter element in the form of bellows that have a first pleated portion and a second pleated portion with parallel pleats. In each pleated portion, the discharge end adjoining the clean chamber has a flat surface, the length of the pleats steadily increasing from one end pleat to the opposite end pleat.

A filter element (1) for filtering liquids, in particular operating media for a motor vehicle, comprises a folded filter medium (2) having outer fold edges (2A) and inner fold edges (2B). The fold edges (2A, 2B) run along a longitudinal axis (5) of the filter element (1). There is provided a support body (3) comprising a first support body section (3A) and a second support body section (3B), wherein the first support body section (3A) faces the inner fold edges (2B), and wherein an envelope (6A) of the outer fold edges (2A) and the second support body section (3B) fit closely – at least in certain sections – with an outer lateral surface (6) of the filter element (1).

The invention relates to a filtering device, comprising a tubular filter element and a carrier part, with the filter element fastened thereon. The carrier part can be inserted between an unfiltered fluid pipe and a filtered fluid pipe. Said pipes can be assembled into a continuous flow pipe, wherein the filter element protrudes into the flow pipe interior.

The invention relates to a filter arrangement (1) for filtering a fluid, e.g. combustion air for a combustion engine. Said filter arrangement has several tubular sections or segments (2, 3). At least part of a wall (4) of at least one tubular section (2) comprises a filter material (4B). At least one tubular section (3) is designed in a bendable manner like a folding joint (5A).

A filter insert for an air filter comprises a bellows (2) which is made from filter material that is folded in a zigzag-shaped manner. The bellows forms a plurality of adjacent pockets (5). First folds (3) are formed at the top of the pockets (5) between the pockets (5) of the folded filter material. A seal is provided on the bellows (2). In order to be able to adjust the bellows to any shape, the folded filter material has an additional folded structure that extends transverse to a longitudinal direction (L) of the pockets (5) such that second folds (4) are formed which extend substantially transverse to said longitudinal direction (L). The front and rear face (6, 7) of the bellows (2) are formed by cuts extending transverse to the longitudinal direction (L) of the pockets (5) in order to be able to cut the bellows (2) to size.
摘要:
The invention relates to a compact filter, particularly a compact air filter for motor vehicles, comprising a compact filter element for the replaceable use in a filter housing, and to a method for producing a compact filter. The compact filter element comprises a filter body made of web-shaped filter medium (18). The web-shaped filter medium (18) is composed of at least one smooth filter medium web (20) and one undulated filter medium web (22) that are placed on top of each other and at least connected in some areas by means of ultrasonic welding. At least one of the filter medium webs (20, 22) consists of a compound made of at least two components. At least one of the components is a synthetic material (48) and at least one of the components is a non-synthetic material (46).

The invention relates to a filter element (1), especially an air filter for a motor vehicle, comprising an inner region (2) having a periphery (U) and a longitudinal extension. The inner region (2) is surrounded, on its periphery, by a fluid-permeable filter material essentially folded lengthwise along the longitudinal extension (L) thereof, and at least a selection of folded edges (3) of the longitudinal folds (18) is mutually fixed by fixing means applied to the folding edges (3). The filter element (1) can be reversibly compressed or stretched by a plurality of transversal folds (3) of the filter material in at least the longitudinal extension (6), and the transversal folds (3) are formed at a discrete angle to the direction of the longitudinal extension. Fixing means (7) are provided for fixing a distance between at least a selection of folded edges (12) of the transversal fold (3).
