Abstract: An exchangeable filter (10), e.g. for filtering lubricating oil in internal combustion engines, having a housing (11) including a vessel (12), a lid (13) and a seal (25). A filter element (21) is situated inside the housing (11) in such a way that an oil inlet (18) is sealingly separated from an oil outlet (19). The lid (13) has a seal holder (15), in which a groove (27) for receiving the seal (25) is arranged. The seal (25) preferably has a beveled area (26), which projects at least partially beyond the seal holder (15). As a result of this beveled area (26), only small mounting forces are required to mount the exchangeable filter (10).

Abstract: An internal combustion engine intake system 10 having a flange area 12 with a first inlet channel 14 and a second inlet channel 13 for each cylinder of the engine and a flap arrangement for closing the second inlet channel 14 arranged in the flange area. The flap arrangement includes an actuating shaft 15 on which flaps 33 are provided for closing each of the second inlet channels 14 when the actuating shaft 15 is operated. The actuating shaft 15 is integrated into the flange area 12 of the intake system 10 and supported by bearing elements 16, which are inserted in mating receptacle profiles 18 formed in the flange area 12, so that the actuating shaft 15 is surrounded by the individual bearing elements 16 over an angular range of substantially greater than 180°.
