- the opening 100 connects in the nozzle-like portion 98, the interior 64 of the filter element 54 with the interior 36 of the adapter nozzle 34 and thus with the discharge 16th
- the adapter element 54 For mounting the oil filter 10, the adapter element 54 is provided with the ring seal 108. Then, the adapter element 94 is inserted with the nozzle-like portion 98 in the axial direction in the adapter sleeve 34 of the filter head 12, so far until the locking lugs 104 engage in the locking groove 106. For this purpose, it may be necessary to rotate the adapter element 94 slightly about the mounting axis 30, so that the positioning pins of the filter head 12 can dip into the positioning holes 1 12. The adapter element 94 is secured against rotation in the filter head 12. The adapter element 94 can be designed as a life component. It may remain connected to the filter head 12 when the filter element 54 is changed.
- the filter element 54 is moved forward with its head-side end plate 58 in the axial direction coaxial with the nozzle-like portion 98, indicated in the figure 1 by an arrow 1 18, on the adapter element 94. It may be necessary to rotate the filter element 54 slightly about the mounting axis 30 so that the locking elements 82 can dip into the gaps between the counter locking elements 14. As soon as the radial sections 88 of the locking elements 82 are located in the axial direction behind the counter-locking elements 14, the filter element 54 can be rotated counter to the closing direction of rotation 90 of the housing-head connection 25 relative to the filter head 12 about the mounting axis 30.

- the stops 92 abut against the corresponding sides of the counter-locking elements 14 and thus prevent further rotation of the filter element 54 relative to the filter head 12.
- the filter element 54 hangs, held by the bayonet connection 84, bottom of the filter head 12th
- the stoppers 92 prevent the filter element 54 from being incorrectly rotated in the closing rotational direction 90 of the housing-head connection 25 after the locking elements 82 have been immersed between the counter-locking elements 114.
- the closing direction of rotation 90 of the housing-head connection 25 thus corresponds to an opening direction of rotation of the bayonet connection 84 and vice versa.
- the housing pot 20 is pushed with its mounting opening 48 ahead in the axial direction, in the figure 1 in the direction of the arrow 1 18, over the filter element 54.
- the bottom-side end plate 60 is centered and guided by the axial legs of the spacer elements 52 in the housing pot 20.
- the housing pot 20 is rotated in the closing direction 90 about the mounting axis 30 and the housing pot 20 is screwed into the connection section 18.
- the lock cylinder 68 is immersed in the sleeve portion 46 in the bottom 42 of the housing pot 20 a.
- the frictional element-housing connection 70 is constructed.
- a torque, which is transmitted via the housing pot 20 and the frictional element-housing connection 70 on the bottom-side end plate 60 is transmitted by means of the support tube 62 to the head-side end plate 58 and thus to the locking elements 82 of the bayonet connection 84.
- a maximum torque which can be transmitted by the frictional connection of the element-housing connection 70 from the housing pot 20 on the filter element 54 is greater than a torque which is required to rotate the locking elements 82 relative to the counter-locking elements 1 14 to the To unlock bayonet connection 84.
- the housing pot 20 Upon further screwing the housing pot 20 takes the filter element 54 and thus unlocks the bayonet connection 84. As soon as the stops 92 in the unlocked state of the bayonet connection 84 abut against the respective adjacent counter-locking elements 1 14, further rotation of the filter element 54 is prevented relative to the adapter element 94 , This avoids that the bayonet connection 84 can lock with the respective adjacent counter-locking elements 1 14. Due to the mechanical resistance opposed by the stops 92, the annular seals 72 slide on the radially inner peripheral side of the sleeve portion 46 and / or the radially outer circumferential side of the lock cylinder 68.
- the frictional element-housing connection 70 slips through and allows further rotation of the housing pot 20 relative to the filter head 12 and the filter element 54.
- the drain openings 69 are covered by the sleeve portion 46 and in the axial direction on both sides each sealed with one of the ring seals 72.
- the lock cylinder 68 closes the drain opening 44 so that no engine oil can escape there.
- the stop collar 32 of the housing pot 20 bears against the free edge of the connection section 18.
- the bayonet connection 84 is released.
- the ring seal 78 and the sealing surface 1 16 seal the connection of the connection collar 76 of the head-side end plate 58 with the adapter element 94.
- the connection between the filter element 54 and the adapter element 94 is vibrationally decoupled by the unlocked bayonet connection 84, so that For example, no operational vibrations from the adapter element 94 can be transferred to the filter element 54 and vice versa.
- the filter element 54 instead of being initially mounted on the filter head 12 by means of the bayonet connection 84, can also be inserted through the mounting opening 48 into the housing pot 20 and fixed in the housing pot 20 by means of the element-housing connection 70. Subsequently, the housing pot 20 with the filter element 54 contained therein can be screwed from below to the filter head 12.
- the bayonet connection 84 is not locked because the closing direction of rotation of the closing direction of rotation 90 of the housing pot 20 is directed opposite. Also in this installation, the filter element 54 is vibration-decoupled in the assembled state of the adapter element 94, since the bayonet connection 84 is unlocked from the outset.
- the housing-head connection 25 is unlocked.
- the housing pot 20 takes by means of the non-positive element-housing connection 70, the filter element 54 against the closing direction 90 with. This causes the locking elements 82 to slide behind the counter-locking elements 14 again so that the bayonet connection 84 is locked again.
- the filter element 54 is fixed in the axial direction on the filter head 12. As soon as the stops 92 on the Gegenverriegeiungs- elements 1 14 abut, the rotation of the filter element 54 is stopped relative to the filter head 12.
- the frictional element-housing connection 70 slips on further rotation of the housing pot 20.
- the invention is not limited to an oil filter 10 of an internal combustion engine of a motor vehicle. Rather, it can also be used in other types of liquid filters, for example in fuel filters or water filters. It can also be used in internal combustion engines outside of motor vehicle technology, for example in industrial engines.

- the end disks 58 and 60 may also be so-called film end disks, which can be tightly connected to the end faces of the filter medium 56 by foaming.
- the passage openings 66 of the support tube 62 may also be formed and / or arranged in other ways than shown in the figures.
- a part of the peripheral wall of the support tube 62 may be impermeable to engine oil.
- connection collar 76 can also be realized as a separate component which can be firmly connected to the end disk 58.
- the adapter element 94 can also be made of a different type of material, for example a metal.
- the head-side connecting parts of the bayonet connection 84, in particular the counter-locking elements 1 14 and the sealing surface 1 16, instead of the adapter element 94 may also be arranged directly on the filter head 12. The adapter element 94 can then be dispensed with.
- the filter element 54 may instead of from radially outward to be flowed through from radially inward to outward. In this case, the functions of the lead 14 and the lead 16 may be reversed.
