ABSTRACT:
In a centrifugal separator for the separation of two liquids the radially outermost part of the separating chamber (7) of the rotor communicates with a central outlet chamber (26) for the separated heavier liquid via a calibrated opening (27). From the outlet chamber (26) a channel (32-34) in a stationary outlet member (31) extends out of the rotor to a reception place for separated heavy liquid. Said channel (32-34) comprises a shut-off valve (35) and has between this and the outlet chamber (26) a calibrated outlet (36) intended to enable a certain liquid flow through at least part of the channel (32-34), while the valve (35) is closed. The throughflow areas of the calibrated opening (27) and the calibrated outlet (36), respectively, are chosen such that, when the valve (35) is closed, the liquid surface in the outlet chamber (26) will be adjusted to a relatively low level, so that unneccessary heat generation is avoided.
