ABSTRACT:
The centrifuge has a self-emptying drum. There are expulsion apertures in the bottom of the drum. The apertures lead from a solids space and can be closed off with a piston slide. A closure chamber that can be charged with closure liquid is associated with the piston slide. The closure chamber communicates with a chamber through a bleed channel in the form of an annular gap and through a valve gap. The annular gap has an extensive cross-section that promotes rapid flow and accordingly especially accelerates bleeding the closure liquid out of the closure chamber into the other chamber. This makes it possible to increase the stroke of the piston slide at a prescribed extraction volume when the drum empties.
