Abstract

In the rotor of a centrifugal separator there is an annular slide (6) for opening and closing of a periphery outlet (12, 13) from a separation chamber (9). The slide (6) at its radially inner edge is connected with and axially fixed relative to the rotor body (1, 2) but has a radially outer edge portion (11) which is axially movable relative to the rotor body (1, 2). This is possible because a portion of the slide, having a substantial radial extension, is flexible. In operation, the flexibility of the slide results in an angular change between portions of the slide situated at different radial distances from the center axis of the rotor.
