Abstract
Sealing ring ( ) for a centrifugal separator with an axially open annular groove ( ) for the sealing ring in a first rotor part ( ) and a relative to the first rotor part ( ) axially movable second rotor part ( ), against which the sealing ring ( ) sealingly abuts. Both the sealing ring ( ) and the groove ( ) have a first annular portion ( and , respectively) turned towards the second rotor part ( ) and a second annular portion ( and , respectively) turned away from the second rotor part ( ). The second portion ( ) of the groove has an outer annular recess ( ) and an inner annular recess ( ) whereas the second annular portion ( ) of the sealing ring ( ) has at least one projection ( ), which is arranged to at least partly fill up the outer recess of the groove ( ). The sealing ring ( ) and the groove ( ) are so shaped and adapted to one another that the sealing ring is kept in the groove locked by its shape and the tightening force is transferred from the sealing ring ( ) to the first rotor part ( ) by pressing the sealing ring ( ) against the bottom ( ) of the groove and so that the sealing ring ( ) upon elastical deformation of the same and/or the first rotor part ( ) can be brought into position in and be taken out of the groove.
