ABSTRACT:
A centrifuge with a self-emptying drum has ejection openings in its jacket that lead out of a solids space and can be blocked off with a piston valve. It has a closure compartment that can be charged with closure fluid and is associated with the piston valve. Part of the closure compartment is divided into an upper and a lower division by a disk. Outflow channels lead out of the drum from the lower division of the closure compartment. The disk can be displaced axially. When it is in its lower position, it hermetically seals off the lower division of the closure compartment from the rest of the compartment. When it is in its upper position, into which it can be displaced hydraulically, the disk allows the lower division to communicate with the rest of the closure compartment so that closure fluid flows out of the compartment through its lower division and through outflow channels. Once a predetermined hydrostatic pressure has been attained in the lower division, the disk automatically returns to its lower position, terminating the outflow of closure fluid.
