Abstract
In a centrifugal rotor an annular slide (5) exposes its one side towards a separation chamber (7) and its opposite side towards an annular chamber (9). The slide (5) can be moved axially by radial displacement of the free liquid surface of liquid bodies in said chambers (7, 9). According to the invention a radial displacement of a free liquid surface in said annular chamber (9) is accomplished without liquid being discharged from the same. Instead an axial movable additional slide (6) is used, which has an axial directed surface exposed into the annular chamber (9). By means of the additional slide liquid can be displaced in the annular chamber (9) radially outwards and inwards.
