Abstract: A microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

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.

Abstract: A rotor of a centrifugal separator, including a central shaft, a plurality of identical discs arranged in a stack on the central shaft, the central shaft having on an outer circumference an engagement contour for a rotationally fixed, axially slidable engagement with a corresponding contour on an inner circumference of the discs, the engagement and corresponding contours engageable with one another in multiple rotational positions at a circumferential distance from one another, and each disc having spacing elements situated at a disc circumferential distance from one another, which spacing elements hold each two adjacent discs at an axial distance from one another, forming an intermediate flow gap having a gap dimension. The spacing elements are formed and configured such that, via different rotational positions relative to one another of adjacent discs, at least two different axial dimensions of the flow gap between adjacent discs may be set.
