A centrifugal separator comprises a centrifuge rotor (3) mounted to a spindle (2) and comprising a rotor casing (4) enclosing a separation space (5). Peripheral ports (8) extend from the separation space through the rotor casing. A valve slide (12) is movable between a closed position closing the peripheral ports and an open position opening the peripheral ports. A closing chamber (16) is provided between the valve slide and the rotor casing. An inlet channel (17) supplies hydraulic medium to the closing chamber to hold the valve slide in the closed position. An outlet passage permits an outlet flow of the hydraulic medium for moving the valve slide to the open position. The outlet passage comprises outlet channels (20) extending though the rotor casing. A valve body (21) is provided in each outlet channel and movable from a closing position to an opening position against the direction of the outlet flow. |
