ABSTRACT:
In a centrifuge rotor provided with sludge channels (25) for conveying sludge radially inwards to a sludge receiving chamber (15), from which the sludge is discharged by means of a central sludge discharge means, the openings of the sludge channels (25) into the sludge receiving chamber (15) are controlled by a slide member (14) being actuated to move in one axial direction by spring means (28). To cause the slide member (14) to move in the other axial direction, a pressure chamber (18), sealed against the sludge receiving chamber (15), is arranged between the slide member (14) and the rotor, and a fluid channel (33) extends through the rotor to the pressure chamber (18), connecting the pressure chamber with a pressure source (35) located outside the rotor. A position regulator (32) is situated in a cavity of the rotor, and is arranged to operate directly on said slide member (14) for regulation of its position.
