Abstract

Centrifugal separator comprising a rotor, which forms an inlet for the liquid which is to be centrifugally treated and an outlet chamber (17) for a liquid separated in the rotor, the outlet chamber (17) surrounding the rotational axis and being so designed that liquid present in the outlet chamber during operation rotates around the rotational axis and has a radially inward facing circular free liquid surface at a certain radial level in the rotor. A stationary discharge device ( 21 ) extends in the outlet chamber (17) from the liquid body radially inward to a central outlet (25) and in the area of the free liquid surface it forms an inlet opening (23), which is directed toward the rotational direction of the liquid body and partly is located in the liquid body, the discharge device also forming a flow channel (28), which connects the inlet opening (23) to the central outlet. To obtain a high outlet pressure with minor risk of air admixture and good stability, the inlet opening (23) is delimited by an edge, which upstream has a front edge portion (30) radially inside the free liquid surface and downstream has a rear edge portion (31) radially outside the free liquid surface, a stra…
