Abstract: An oil mist separator (10) for a crankcase ventilation (11) such as in an internal combustion engine (13) for separating oil particles from a gaseous fluid, in particular blow-by gas is disclosed. The oil mist separator (10) has at least one nozzle plate (24). The at least one nozzle plate (24) is arranged in a flow way of the gaseous fluid. The nozzle plate (24) has at least one aperture (26; 126) for the gaseous fluid. The oil mist separator (10) further has at least one impact surface (32; 132). The at least one impact surface (32; 132) is arranged downstream of the nozzle plate (24) relating to the flow of the gaseous fluid. The at least one impact surface (32; 132) can be moved away from the at least one nozzle plate (24) in an opening direction (36) against a pretension force by influence and dependent on a flow of the gaseous fluid through the at least one aperture (26; 126).

Abstract: The device includes an upstream pipe, extending along a first direction, and in which at least one purification member is housed, a first downstream pipe, extending along a second direction, and in which at least one heat exchanger is housed, and a second downstream pipe configured to be connected to an exhaust gas outlet tube. The device also includes an intermediate chamber comprising an exhaust gas inlet communicating with the upstream pipe, downstream from the at least one purification member, a first exhaust gas outlet communicating with the first downstream pipe, and a second exhaust gas outlet communicating with the second downstream pipe. The first direction and the second direction form an angle between them comprised between 0° and 90°.

Abstract: Disclosed is a device for swirling and mixing exhaust gases recycled in the intake duct (1) of an internal combustion engine via a recycling conduit (2). The device is formed of two control flaps (3, 4) in the form of toroidal portions, mounted rotatably about axes of articulation (6, 7), the control flaps (3, 4) being displaceable in rotation between, on the one hand, a rest position in which they are retracted along the inner wall of the intake duct (1) so as to expose the entire cross-section of said duct and, on the other hand, an active position in which they are pulled towards one another so as to reduce said cross-section, and also formed of an actuator which makes it possible to control displacement of the control flaps (3, 4) between the active position and rest position thereof.
