Abstract
A centrifugal separator includes a centrifuge rotor mounted to a spindle and includes a rotor casing enclosing a separation space. Peripheral ports extend from the separation space through the rotor casing. A valve slide is movable between a closed position closing the peripheral ports and an open position opening the peripheral ports. A closing chamber is provided between the valve slide and the rotor casing. An inlet channel 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 includes outlet channels extending though the rotor casing. A valve body is provided in each outlet channel and is axially movable from a closing position to an opening position against the direction of the outlet flow.
