Classification: CPC B  F | IPC F

Claim 0:
1. A blow-by gas filtration assembly fluidically connectable to a crankcase ventilation circuit of an internal combustion engine to receive blow-by gases and filter the blow-by gases from suspended particles contained therein, wherein the filtration assembly has an axis and comprises:
a main body comprising a filtration chamber which extends along said axis (X-X) comprising a flow aperture delimited by an aperture edge which extends concentrically relative to the axis;
a filter group which comprises a filtering media, cylindrical hollow, comprising a filter cavity, radially crossable in filtration by the blow-by gases;
a command group supported on the main body operationally connected to the filter group to command the filter group in rotation about the axis;
an annular collar operationally connected to the filter group;
an annular alignment and fixing group, positioned between the aperture edge and the annular collar, adapted to perform rotational and fluidic mechanical coupling of the filter group with the main body, comprising:
i) a dynamic element comprising a first radial face engaged at the aperture edge and a second radial face radially facing the annular collar;
ii) an elastically yielding annular element positioned between dynamic element and annular collar, wherein the elastically yielding annular element is elastically yielding in a flattened configuration in which the elastically yielding annular element is volumetrically compressed between the second radial face and the annular collar to integrally engage the dynamic element and the annular collar to rotate therewith.
