an outer surface facing away from the axial center axis of the disc element; a radially inner peripheral edge; a radially outer peripheral edge; spacing members on at least one of the inner and outer surfaces for maintaining a mutual distance to an adjacent disc element, the spacing members having the shape of circumferentially distributed ribs extending from the outer peripheral edge towards the inner peripheral edge and delimiting between them flow channels for a gaseous fluid to be cleaned; and a plurality of radial projections extending radially outwardly from the outer peripheral edge, said projections being configured such that several whole ones thereof are located between adjacent ribs, as viewed in the circumferential direction of the disc element. ### Claim 2 (depends on 1) The disc element according to claim 1, wherein the projections have a rounded free end. ### Claim 3 (depends on 1) The disc element according to claim 1, wherein the projections have a first side lying in a plane with an axial normal co-axial to the center axis and connected to the inner surface of the disc element, and a second side which likewise lies in a plane with an axial normal and connected to the outer surface of the disc element, wherein the first side of the projections is configured to be able to engage and be supported by the second side of the projections of an adjacent disc element. ### Claim 4 (depends on 1) The disc element according to claim 1, wherein the projections have first and second opposite sides which are planar, curved or sloping in a parallel manner to be able to engage each other in a stack of adjacent disc elements. ### Claim 5 (depends on 4) The disc element according to claim 4, wherein one of the projections is formed as an extension of each rib. ### Claim 6 (depends on 4) The disc element according to claim 4, wherein the ribs are formed on the inner surface of the disc element. ### Claim 7 (depends on 1) A method of using the disc element of claim 1 in forming of a rotor for a centrifugal separator for cleaning of a gaseous fluid, comprising the step of stacking a plurality of the disc elements onto a rotor core member. ### Claim 8 A conical disc element for centrifugal separators for cleaning of a gaseous fluid, the disc element comprising: an inner surface facing the axial center axis of the conical disc element; an outer surface facing away from the axial center axis of the disc element; a radially inner peripheral edge; a radially outer peripheral edge; spacing members on at least one of the inner and outer surfaces for maintaining a mutual distance to an adjacent disc element, the spacing members having the shape of circumferentially distributed ribs extending from the inner peripheral edge towards the outer peripheral edge and delimiting between them flow channels for a gaseous fluid to be cleaned; a plurality of radial projections extending radially inwardly from the inner peripheral edge, said projections being configured such that several whole ones thereof are located between adjacent ribs, as viewed in the circumferential direction of the disc element. ### Claim 9 (depends on 8) The disc element according to claim 8, wherein the projections have a rounded free end. ### Claim 10 (depends on 8) The disc element according to claim 8, wherein the projections have a first side lying in a plane with an axial normal co-axial to the center axis and connected to the inner surface of the disc element, and a second side which likewise lies in a plane with an axial normal and connected to the outer surface of the disc element, wherein the first side of the projections is configured to be able to engage and be supported by the second side of the projections of an adjacent disc element. ### Claim 11 (depends on 8) The disc element according to claim 8, wherein the projections have first and second opposite sides which are planar, curved or sloping in a parallel manner to be able to engage each other in a stack of adjacent disc elements. ### Claim 12 (depends on 11) The disc element according to claim 11, wherein one of the projections is formed as an extension of each rib. ### Claim 13 (depends on 11) The disc element according to claim 11, wherein the ribs are formed on the inner surface of the disc element. ### Claim 14 (depends on 8) A method of using the disc element of claim 8 in forming of a rotor for a centrifugal separator for cleaning of a gaseous fluid, comprising the step of stacking a plurality of the disc elements onto a rotor core member.
