PCT No. PCT/SE91/00100 Sec. 371 Date Oct. 10, 1991 Sec. 102(e) Date Oct. 10, 1991 PCT Filed Feb. 13, 1991 PCT Pub. No. WO91/12082 PCT Pub. Date Aug. 22, 1991.A centrifugal separator of the type including a rotor, which is supported by a driving shaft and which forms a separation chamber and an inlet chamber. The inlet chamber being delimited by a dividing wall. An inlet tube extends axially through the dividing wall at one axial end of the inlet chamber at which the inlet channel in the tube opens. In the inlet chamber there is arranged a number of separating discs. A central part of the inlet chamber is connected to an outside space through an evacuating channel. In order to efficiently and gently separate a supplied liquid mixture without demanding a large space in the centrifugal separator, the inlet device is provided with a baffle which, between the opening of the inlet channel and the discs, extends from the rotational axis of the rotor and delimits a liquid filled inlet space. The liquid in the inlet space flowing during operation from the inlet channel radially outwards into the liquid body.
