A centrifugal rotor contains a member slidable axially of the rotor to open and close its peripheral outlets, and on the side of this member opposite from the separating chamber is an operating chamber for receiving liquid to maintain the slidable member in its closing position. Said member is moved to its opening position by draining part of the liquid from the operating chamber, the remaining liquid acting to return the slidable member to its closing position when only part of the material in the separating chamber has been discharged through the peripheral outlets. Means are provided for adjusting the magnitude of the force by which the slidable member is kept in its closing position, thereby enabling adjustment of the amount of material discharged from the separating chamber upon each opening of the peripheral outlets. |
