Abstract:
A rotor of a centrifugal separator, wherein the rotor comprises a central shaft on which an axially movable plate stack, formed by multiple plates, is arranged. A stack base is arranged on the shaft under the plate stack. A stack cap is arranged in an axially moveable manner on the shaft above the plate stack. The rotor includes a compression spring surrounding the shaft, with a first end supported on the shaft and a second end supported on the stack cap, pressing the plate stack together. The rotor includes a sleeve-like extension arranged on the stack cap, projecting into the plate stack and surrounding the shaft with a separation. The compression spring is located inside the extension, at least over a majority of the axial length thereof. A support surface for the second end of the compression spring, is arranged on a base of the extension.

Claim (Index 33):
The rotor as recited in  claim 22 , wherein the shaft, seen in its axial direction, is made up of two shaft parts, a first shaft part, which provides a rotational bearing of the rotor, being made of metal, a second shaft part, bearing the plate stack, being made of plastic and being connected to the first shaft part in rotationally fixed and axially fixed fashion, and the second shaft part having on its outer circumference an engagement contour for a rotationally fixed, axially movable engagement with a counter-engagement contour on an inner circumference of the plates of the plate stack.
