ABSTRACT:
A centrifugal separator has a rotor, which forms an inlet chamber, a separation chamber (5) and an outlet chamber (10), in which a liquid, separated during operation, forms a rotating liquid body with a radially inwardly directed free liquid surface. A stationary discharge device (17) is provided together with rods 20 which are arranged to entrain, during the operation of the rotor, the liquid present in the outlet chamber (10) and to admit flow of such liquid radially outwardly to an inlet (19) in the discharge device (17). The rods are distributed around the rotational axis and rotate with the rotor and form flow spaces which extend axially, radially and in the circumferential direction. They entrain the liquid in the outlet chamber (10) efficiently and to admit flow of the liquid radially outwardly to the inlet (19) with reduced risk of air admixture. A wing extending radially and axially in the outlet chamber may also be provided.
