Abstract
A centrifuge has ejection openings in the jacket of the drum to which channels extending from the solids space lead. The flow through the channels can be blocked off by an annular valve body. A closure compartment is associated with the valve body. Closure fluid is supplied to the closure compartment through a line from a catch gutter. The line consists of two connected components. The components can be separated by a piston with a flowthrough channel. When the piston is in the separating position, in which it blocks off an opening in the first line component, the flowthrough channel connects the second line component with an off-flow channel that is open to the atmosphere. In this position the second line component and the closure compartment are depressurized so that the valve body can move into an opening position. This opening motion is reinforced with opening water conveyed through three channels to an opening chamber. The first channel communicates with the second channel, which supplies opening water to the extensive active surface of the piston when the piston is to be moved into the separating position in which its smaller active surface blocks off the opening.
