  • Patent number: 9993756
    Abstract: The invention relates to a filter (10) having at least a first bayonet joint (22). The first bayonet joint (22) has a first bayonet slotted guide (26) with two locking positions that are axially spaced apart from one another for a first bayonet projection (24) of the first bayonet joint (22). By rotating a filter part for releasing the first bayonet joint (22), the first bayonet projection (24) may be moved from the second locking position into the first locking position. The filter (10) preferably has a second bayonet joint (28). The second bayonet joint (28) is preferably embodied such that, by further rotation in the same direction of rotation, it is released in that a second bayonet projection (30) is moved out of a third locking position of a second bayonet slotted guide (32) of the second bayonet joint (28) after the first bayonet projection (24) has been stopped in the first locking position.

  • Patent number: 9656194
    Abstract: A filter has a filter cup, a filter element arranged in the filter cup, and a filter head. Filter cup and filter head are connected by a releasable bayonet-type connection with interacting locking parts connected to filter cup and filter head. A locking nose on the first locking part and a recess on the second locking part interact. The recess has an insertion/removal region for joining and separating locking nose and recess and also a locking region for hooking the locking nose. A spring between filter cup and filter head generates pretension on the locking nose in the recess. The recess has a locking shoulder with a shoulder tip between locking region and insertion/removal region. The locking nose has a locking tip. When locking tip and shoulder tip contact each other, the locking nose is forced by the spring into the locking region or into the insertion/removal region.
