Abstract

The invention concerns a centrifugal separator with a rotor (15), in which a flexible member (28), e.g. a hose, extends a distance along the periphery of the rotor. The hose defines two parallel channels (29, 30), which form a separation chamber in the rotor and extend from the peripheral part of the rotor towards the rotor center; from there axially out of the rotor (15) at one axially directed side thereof, around the rotor to its opposite side and to a point (27) aligned with the rotor axis (C). During the operation of the rotor the hose may be rotated intermittently around its longitudinal axis relative to the rotor body, so that the radially inner and outer walls of the separation chamber are changing places.
