摘要： The invention relates to the arrangement of a filtering element (100) for a device for purifying gas from the crankcase of an internal combustion engine, which includes: a filtering element (15) mounted so as to rotate about an axis and having an annular filtering medium (20); a rotor element (18) capable of being part of a rotating system, making it possible to turn the filtering element by means of notches formed on the outer surface (F) of a sleeve (19). The flanges (31, 32) of the filtering element (15) are attached to one another in an inner space defined by the medium (20), typically by snap-fitting, using at least one retaining member (44) and an anchor portion engaging with one another with an anti-rotation effect. The anchoring portion is provided with inner projections (38) forming contact surfaces (SC), preferably angular, which are inserted into the notches of the sleeve (19) when the rotor element (18) is inserted into the inner space.

摘要： The invention relates to an arrangement (10) for controlling the flow of material-laden gases (G) that is arranged upstream of an oil separation system and comprises: a non-return valve (16) that is movable at least in part for defining a first passage for a first forward flow direction in the event of positive pressure, a bypass valve (20) that moves backwards under the influence of negative pressure in order to free up a second passage for a second opposite flow direction, and a stationary portion (12) that forms a seating surface (S) for the bypass valve. The bypass valve, biased against said surface (S) by a resilient return element (27), defines the seat (23a) for the non-return valve (16). In the event of sufficient negative pressure, the two valves (16) and (20) move backwards together despite the element (27) and complement one another in order to divert and guide the flow along an escape path corresponding to the second passage.
