A centrifuge with a self-emptying drum including drum jacket having ejection openings for the solids that collect in the solids space. The openings can be blocked off with a piston valve with which is associated a closure compartment that can be charged with closure liquid. The closure compartment has outlet channels around it that can be blocked off with a hydraulically controlled valve body. When the valve is open, the closure liquid flows into a compartment with choked run-off bores. The compartment has sufficient capacity for part of the closure liquid. The compartment has at least one run-off channel that has a valve with a piston that can be shifted hydraulically in it. When the solids space is to be completely emptied, the closure liquid flowing into the compartment moves the valve piston into the opening position so that the closure liquid can flow off through a channel. If the solids space is only to be partly emptied, the valve piston is retained in the sealing position, in which it is charged with pressure liquid on the side facing away from the compartment. |
