Abstract
In a centrifugal separator, an outlet member (9) is rotatable in the centrifuge rotor (1, 2) in a way such that it may be entrained in rotation by liquid supplied to the rotor. The outlet member (9) has an outlet channel (11) leading from one place within the rotor, where a separated mixture component is present, to a reception place (13) for the mixture component. A first means (19) is arranged to counteract rotation of the outlet member (9) so that a desired relative movement is obtained between the outlet member (9) and the separated mixture component in the rotor which is to be removed. A second means (27-30) senses the magnitude of the force by which the outlet member (9) is counteracting the braking effect of said first means. The first means (19) is connected with the second means (27-30) and arranged to accomplish a desired relative movement between the outlet member (9) and the separated component in the rotor in response to the magnitude of said sensed force.
