<p>In a centrifuge rotor provided with slude channels for conveying sludge radially inwards to a sludge receiving chamber, from which the sludge is discharged by means of a central sludge discharge means, the openings of the sludge channels into the sludge receiving chamber are controlled by a slide member being biassed to move in one axial direction by spring means. To cause the slide member to move in the other axial direction, a pressure chamber, sealed against the sludge receiving chamber, is disposed between the slide member and the rotor, and a fluid channel extends through the rotor to the pressure chamber, connecting the pressure chamber with a pressure source located outside the rotor. A position regulator is disposed in a cavity of the rotor, and is arranged to operate directly of said slide member for regulation of its position.</p> |
