The invention relates to a device (1) for removing impurities from the lubricating oil of an internal combustion engine, wherein the device (1) has a filter insert (2) at the bottom in the operating position of the device and a centrifuge (3) thereabove having a rotationally drivable rotor (30), wherein the filter insert (2) and the centrifuge (3) are arranged one above the other in a common two-part housing (4), which is closed during the operation of the device (1) and which has a removable upper closure cover (41) and a fixed lower housing part (42), wherein a removable intermediate cover (5) is arranged in the housing (4) between the filter insert (2) and the centrifuge (3), which intermediate cover is inserted in a sealing manner and separates a lower filter space (12), which is under the lubricating oil pressure during the operation of the device (1), from an unpressurized upper centrifuge space (11), wherein the intermediate cover (5) is supported radially outside on the closure cover (41) when the closure cover (41) is in the closed state, wherein a rotor shaft (33) rotatably supporting the rotor (30) is attached in or on the intermediate cover (5) by means of a lower end (35) of the rotor shaft and wherein the rotor (30), the intermediate cover (5) together with the rotor axis (33), and the filter insert (2) can be removed from the housing (4) when the closure cover (41) is in the open state. The device (1) according to the invention is characterized in that the closure cover (41) has a supporting surface at the center of the closure cover on the inside and that the rotor shaft (33) is supported axially on the closure cover (41) at the supporting surface by means of an upper end (36) of the rotor shaft when the closure cover (41) is in the closed state. |
