The centrifuge has a self-emptying drum. The jacket of the drum has expulsion apertures that lead from the solids space and that can be closed off by a piston slide. With the piston slide is associated a closure chamber. The closure chamber has channels for supplying closure liquid and communicates through a let-off channel in the form of an annular gap with a chamber. The inside diameter of the chamber equals the outside diameter of the closure chamber. The chamber can accommodate all the closure liquid in the closure chamber. This makes it possible to completely empty the closure chamber, so that there is no residual closure force on the piston slide. |
