A self-emptying centrifuge drum has a piston slide that controls openings in the jacket. The piston slide is fastened without play and without axial motion to the drum in the vicinity of the inner centering surface. The requisite axial motion of the slide in the vicinity of the outer centering surface is ensured by an elastically deformable area with an axial spring coefficient that is low in relation to its radial rigidity. This novel way of guiding the piston slide, prevents one-sided frictional forces in the vicinity of the centering surfaces with concomitant wear as well as irregular opening of the slide.
