Abstract:
1. A centrifugal separator for separating particles from a fluid, the centrifugal separator comprising: an axially extending housing having a central axis and a structural element, the housing having a raw air side at a first axial end and a clean air side at an opposing axial end, the housing circumferentially surrounding an interior space arranged within the housing; wherein the structural element is a partition extending in a traverse direction relative to the central axis, the partition extending fully across and closing over the interior space, a radially inner side of the housing closing onto the partition at its periphery, separating the raw air side from the clean air side of the housing; wherein the partition is formed together with the housing as a unitary one-piece component of the housing; wherein the partition has an opening extending axially through the partition; wherein the partition forms a tubular member having a tubular outer wall with an open interior, the tubular member extending axially through the partition opening, the tubular member having an inflow opening and an outflow opening arrange at opposing axial ends of the tubular member, the tubular member having a discharge port extending radially through the tubular outer wall; a cyclone cell formed as a drop part component separate from the partition and housing, the cyclone cell including: wherein a the tubular cyclone cell outer wall is arranged within the open interior of the tubular member of the partition, a radially outer surface of the tubular cyclone cell outer wall contacting and secured onto a radially inner surface of the tubular member of the partition; wherein the cyclone cell is adapted to produce a swirl in a fluid that is flowing in through the inflow opening and exits through the outflow opening; wherein the cyclone cell is form-fittingly embedded by injection molding into the structural element.
