Abstract: An articulated assembly for pipelines, including: two articulated sections; wherein one of the two articulated sections engages into another one of the two articulated sections; and a locking body that engages at least in areas between the articulated sections and cooperates with a locking contour on one of the articulated sections and with a locking section of the other articulated section such that a relative movement between the articulated sections is limited; wherein a guide means is provided on the articulated sections such that the two articulated sections can be joined together in a defined rotational position in relation to one another.

Abstract: The invention relates to a coupling arrangement (10) for pipelines, with a female coupling section (20) and a male coupling section (40) as well as a locking element (60) which at least in regions engages between the coupling sections (20, 40) and is secured on a coupling section (20), one of the coupling sections (20) comprising a locking contour (34) which cooperates with a locking contour (64) of the locking element (60), and the locking element (60) having a blocking section (62) which cooperates with a blocking section (52) of the other coupling section (40) such that a lateral movement between the coupling sections (20, 40) can be restricted.

Abstract: In an air filter housing (100) for an air filter element (2) with at least one housing bottom part (10) into which the air filter element (2) can be inserted completely or with a substantial portion of its length and a cover element (20) to be connected to the housing bottom part (10), on the housing bottom part (10) and on the cover element (20) at least one connector socket (14, 15) for connection to a hose conduit is provided, respectively. The connector socket for the side of the air filter element facing the cover element (20) is designed as a deflecting connector socket (14) that extends at least partially outside of the cross-sectional area covered by the air filter element (2) and that is connected to the housing bottom part (10).

Abstract: A filter unit includes at least one housing and at least one filter element designed for axial flow between its end faces that is inserted with at least a portion of its length into a tubular filter protection element and connected thereto and provided about its circumference with at least one endless sealing collar that is supported on the filter protection element and by clamping means is pressed against a sealing flange provided on the housing.

Abstract: The invention relates to a filter unit which comprises at least one housing and at least one filter element the front faces of which allow a liquid to axially flow through. Said filter unit is inserted across at least part of its length into a tubular filter protection element (10) and is connected thereto and has, on its outer periphery, at least one continuous sealing collar which is supported on the filter protection element and can be forced against a sealing flange on the housing by means of tensioning elements. Said tensioning elements are constituted by at least one insertion ramp (25) on the housing and at least one projection (15) on the filter protection element (10), which projection slides down the insertion ramp. The insertion ramp (25) extends from a point of insertion (25.5) in the interior of the housing in a direction at an angle to the direction of flow towards the housing (23) and in an axial direction towards the scaling flange on the housing (23).

Abstract: In a filter housing (100) for at least one axial flow filter element (70) capable of receiving axial flow between its end faces and having at least one continuous sealing collar on its outer circumference which can be pressed against a sealing flange (17) on the housing, a plurality of filter elements (70) can be inserted side by side into cutouts (19) of a common clamping frame element (30). Each of the sealing collars rests on the clamping frame element (30) which is plane parallel to the at least one sealing flange (17) and displaceable toward the sealing flange (17) by a clamping device (50).
