Abstract
A centrifugal separator having a device for the transformation of kinetic energy of a liquid rotating in a discharge chamber around a rotational axis to pressure energy includes a discharge element for the discharge of liquid out of the discharge chamber, which discharge element has a radially outer part shaped as a body of revolution about the rotational axis and is arranged to be located in a rotating liquid body in the discharge chamber, and at least one outlet channel formed in the discharge element and having an inlet opening located in a surface of the body of revolution and elongated in the liquid flow direction, the inlet opening connecting to the interior of an outlet tube via the outlet channel. The outlet channel has a defined axial height and a defined width which vary along their extension from the inlet opening to the connection to the outlet tube in such a way that a defined aspect ratio h/w decreases along at least a part of the extension of the outlet channel. A defined aspect ratio h/w is larger than 1 in an outer first part of the outlet channel and decreases to smaller than 1 in an inner second part of the outlet channel and the height decreases inwardly along the length of the outlet channel.
