Abstract:
1. A centrifuge for separating solid matter from a liquid, in particular from a lubricating oil of an internal combustion engine, comprising a centrifuge housing and a centrifuge rotor including a rotor shaft, which is rotatably mounted in the centrifuge housing, which is drivable by a separate drive and which is formed partially as a hollow shaft, and having a centrifuging drum, being rotatable with the rotor shaft, the centrifuging drum comprises an interior space being suppliable with the liquid to be separated via a cavity of the hollow shaft, wherein the centrifuging drum is provided with at least one outflow opening for liquid to flow out of the interior space, the centrifuging drum comprising a drum lower part and a drum upper part which bears against the drum lower part and which is guided in an axially movable manner on the rotor shaft and which is movable by a disengagement mechanism parallel to the rotor axis into an open position in which, for self-emptying of the interior space, the drum lower part and drum upper part are spaced apart from one another and are rotatable with the rotor shaft wherein a pressure-exerting mechanism for increasing the pressure forces between the drum upper part and drum lower part in the closed state of the centrifuging drum engages on the drum upper part, the pressure-exerting mechanism includes pressure-force-generating means which is controlled by centrifugal force, the centrifugal-force-regulated pressure-force-generating means is at least one of activateable or deactivatable by means of the disengagement mechanism.
