ABSTRACT:
A centrifuge with a self-emptying drum is provided with expulsion openings in its jacket that lead from the solids space and that can be closed off by a piston slide. The piston slide is associated with a closure chamber, which can be supplied with a closure fluid and which has outlet channels around it that can be closed off by a valve body and that open into a blocking chamber. The blocking chamber can accommodate part of the closure fluid taken in by the closure chamber. The valve body and the piston slide are moved into the opening position for partial emptying. The valve body remains in the open position during partial emptying. The outlet channels are blocked by closure fluid taken in by the blocking chamber. This blocking fluid initiates the closing motion of the piston slide while closure fluid continues to be supplied to the closure chamber.
