Abstract
A centrifugal separator comprises a rotor having two separate coaxial rotor parts, means for axially interlocking these parts, and means arranged for discharging liquid from the separation chamber of the rotor so that the liquid pressure in the separation chamber varies. The separator is specifically characterized in that one of the rotor parts comprises two separate coaxial walls, an inner wall and an outer wall, that the inner wall is supported axially against the other rotor part, that the axially interlocking means connects the outer wall with the other rotor part, that a space is formed between the two walls, and that means are arranged to provide a force of substantially constant magnitude in the space between the walls during operation of the separator, which force acts to axially separate the walls.
