<p>The invention concerns a filter unit (10, 20, 30, 40) for an internal combustion engine (1), wherein the filter unit (10, 20, 30, 40) comprises a filter housing (12) and means (14, 15) for transfer of a fluid between the filter unit (10, 20, 30, 40) and the engine (1) at a first end (16) of the filter housing (12) The invention is characterized in that the filter unit (10, 20, 30, 40) comprises a cylindrical wall (11, 21, 23, 31, 41) that is connected to the filter housing (12), that the cylindrical wall (11, 21, 23, 31, 41) is configured for collecting leakage fluid when disconnecting the filter unit (10, 20, 30, 40) from the engine (1), and that the cylindrical wall (11, 21, 23, 31, 41) is configured to be arranged in at least two different states in relation to the filter housing (12) comprising an inactive state, when the filter unit (10, 20, 30, 40) is in its filtering operational position and an active state, in which it projects a distance from the first end (16) of the filter housing (12) for collecting leakage fluid when disconnecting the filter unit (10, 20, 30, 40) from the engine (1). The invention also concerns an internal combustion engine (1) comprising a filter unit (10, 20, 30, 40) of the above type.</p> |
