Blow-by gas filtration assembly with support and control shaft

A blow-by gas filtration assembly fluidically connectable to a ventilation circuit of base 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 extending along said axis and an outlet mouth formed at the axis;
• a filter group, extending along the axis having a hollow cylindrical shape comprising a central chamber, wherein the filter group is housed in said filtration chamber and is traversable radially by the blow-by gases;
• a motor group operatively connected to the filter group to control the filter group in rotation around the axis, wherein the motor group comprises a rotor and a stator;
• a support and control shaft, configured as a hollow body extending along the axis comprising a motor portion on which the rotor is housed and a filter portion on which the filter group is housed, wherein the rotor and the filter group are mounted integrally with the shaft respectively to the motor portion and to the filter portion so that a rotation of the shaft and therefore of the filter group corresponds to a controlled rotation of the rotor;
• wherein the filter portion comprises an outlet duct of the filtered blow-by gases in which outflow of said filtered blow-by gases towards the outlet mouth takes place.
