Abstract: A device for treating exhaust gases includes at least one purification member with a substrate for purifying the exhaust gases, a heat exchanger axially located beyond an axial end of the substrate, a body, a valve comprising a flap arranged in an internal volume of the body. An exchanger inlet and exchanger outlet open into the internal volume. At least 45% of a volume of the body is in a virtual space located in an axial extension of one or more purification substrate(s). The body comprises at least one first orifice in fluid communication with a purification member outlet, and a second orifice defining an outlet for the exhaust gases.

Abstract: A sensor head, capable of sampling and maximizing a stream of gas before transmitting the stream of gas to a sensitive element of a sensor, includes a guide and a capsule. The guide is substantially cylindrical according to a first axis, hollow and closed with an exception of a flow inlet comprising two openings facing each other, pierced in the guide along a second axis substantially perpendicular and coplanar to the first axis, and a flow outlet comprising a hole drilled in the guide along the first axis. The capsule is substantially cylindrical along a third axis substantially parallel to the first axis, including the guide, hollow and closed with an exception of a mouth pierced in the generating surface of the capsule according to a fourth axis substantially perpendicular to the first axis and to the second axis and substantially perpendicular and coplanar to the third axis. A sensor, preferably of the photoacoustic type, includes such a head.

Abstract: An exhaust valve comprises a substantially tubular body, defining a passage section and extending along an extension axis, and a flap positioned in the tubular body across the passage section. The flap rotates about an axis of rotation, secant to the extension axis, between a closed orientation where the flap closes off the passage section and an open orientation where the flap frees the passage section. The tubular body comprises two flanges that are substantially symmetrical to one another and an annular sealing ring is positioned and maintained between the two flanges.

Abstract: A brazing process includes placing an accessory on a tube and interposing a brazing material between a bearing surface of the tube and a complementary bearing surface of the accessory. The brazing material is melted. The bearing surface and the complementary bearing surface together define a chamber having a converging portion whose height perpendicular to the bearing surface decreases radially away from the orifice. The converging portion of the chamber has a radial width greater than one times the thickness of the tube, so that the brazing material is distributed by capillary action in the chamber, and binds the bearing surface and the complementary bearing surface to one another.

Abstract: A purification method comprises providing a purification device comprising at least one exhaust gas purification member having an upstream surface through which the exhaust gas enters the purification member and a downstream surface through which the exhaust gases exit the purification member. The method further includes, in the absence of forced circulation of the exhaust gas through the purification member by an engine of the vehicle, heating radiatively at least either the upstream zone or the downstream zone, for example before starting the engine of the vehicle.

Abstract: An exhaust valve includes a body defining a passage and a flap that pivots about an axis relative to the body to selectively close/open the passage. An actuator moves the flap and a device couples the flap to the actuator. This coupling device comprises: a compression spring having a proximal end that rotates about the axis with a first element between the flap and an actuator output shaft and a distal end; a seat engaged with the distal end, while the seat is fixed in rotation about the axis with the first element, and a torsionally-rigid transmission member fixed in rotation about the axis with the first element and that immobilizes the distal end relative to the proximal end in a plane that is orthogonal to the axis. The transmission member has a slot that is elongated parallel to the axis and is traversed by the distal end.

Abstract: A composite structure comprising a substantially planar portion and a border arranged on the border of the substantially planar portion. A first linking zone arranged at one end of the border along a first axis and able to accommodate a first metal insert and a second linking zone arranged at another end of the border along the first axis and able to accommodate a second metal insert symmetrical to the first metal insert. An insert comprises a substantially planar base arranged perpendicular to the first axis and comprising, substantially at a center of the substantially planar base, a piercing. A first substantially planar wing is arranged perpendicular to the substantially planar base and a second substantially planar wing arranged perpendicular to the substantially planar base and the first substantially planar wing.
