ABSTRACT:
The invention relates to a rotor for a centrifuge for cleaning a liquid, in particular the lubricating oil of an internal combustion engine, wherein the rotor is designed in two parts, namely, on the one hand, a drive part and, on the other hand, a dirt-collecting part comprising a dirt collection area, wherein the dirt-collecting part can be connected to the drive part to the rotor, and wherein the dirt-collecting part can be detached, for disposal or cleaning, by being pulled off axially from the drive part. The rotor according to the invention is characterized in that the drive part and the dirt-collecting part are provided with an interacting connection arrangement which, when the dirt-collecting part is connected to the drive part, secures the dirt-collecting part against axial withdrawal relative to the drive part, and in that the dirt-collecting part is provided with an unlocking arrangement which interacts with the connection arrangement and which includes at least one gripping and actuating element that protrudes upward above the dirt-collecting part.
