Abstract: A manufacturing assembly for manufacturing a metal part comprises a flattening module having a trolley and at least one pressing roller. The flattening module is movable along a hemming of the metal part. The flattening module comprises at least one pressing actuator that is arranged to move the at least one pressing roller in a determined pressing direction relative to the trolley and to place the pressure roller bearing against the free surface such that the at least one pressing roller exerts pressure on the free surface in said determined pressing direction. The pressure increases auto-adaptively with an altitude of the free surface in a direction opposite the determined pressing direction.

Abstract: An exhaust component comprises a main casing and at least one partial casing pressed against the main casing. In a developed state, the partial casing has an elongated shape along a longitudinal line and is defined along a transverse direction, substantially perpendicular to the longitudinal line, by two side edges opposite one another. The partial casing has a given developed longitudinal length. The partial casing has no fastening to the main casing on at least one longitudinal segment, and the longitudinal segment extends from one side edge to the other and extends in total over a cumulative developed longitudinal length of at least 20% of the given developed longitudinal length.

The flattening module is movable along a stapling line of the metal part. The flattening module comprises at least one pressing actuator that is arranged to move the at least one pressing roller in a determined pressing direction relative to the trolley and to place the pressure roller bearing against the free surface such that the at least one pressing roller exerts pressure on the free surface in said determined pressing direction.

Abstract: An ammonia generating device is used for the treatment of exhaust gases of internal combustion engines, particularly for motor vehicles. The device includes a tank having a body capable of releasing ammonia by desorption. The device is also provided with a first single connection member comprising an electrical connection to supply the device with electricity and a fluid connection to allow evacuation of the ammonia produced following the desorption reaction.

Abstract: A valve comprises a support including an exhaust gas passage opening, a plug able to move by tilting between a plugging position and a release position of the passage opening, and an elastic strip for returning the plug to its plugging position. The elastic strip has a first end fastened to the support and a second end bearing on the plug. The second end is able to slide on the plug between a first position, in which the plug is in the plugging position, and a second position, in which the plug is in the release position. The plug includes a stop forming a hard spot that cooperates with the second end of the elastic strip when the elastic strip is in the first position, so that this stop forms an obstacle for movement of the second end of the elastic strip from the first position to the second position.

Abstract: A device for storing and supplying ammonia to an exhaust line of an automobile vehicle, includes a solid material provided for absorbing the ammonia, a reservoir for storing the solid material, and a heating unit to heat the solid material to desorb the ammonia. The solid material comprises solid elements with a mass of less than 50 grams. The heating unit is insulated from the reservoir. The device also includes a first assembly for transferring solid elements from the reservoir to the heating unit.

Abstract: A valve suitable for closing an orifice (36) of a structure (10) of a silencer (1) for a motor vehicle exhaust line, includes a closing component (44) which is connectable to the structure (10) and capable of adopting a position for closing the orifice (36). The closing component (44) is capable of rising by bending from its closure position. The closing component (44) includes a closure plate (54) capable of closing the orifice (36) and at least one connection plate (56) capable of connecting the closure plate (54) to the structure (10), the closure plate (54) and the or each connection plate (56) having differing thicknesses and/or being made of materials having differing mechanical characteristics.

Abstract: This silencer (10) for a motor vehicle exhaust line of the type comprising: a casing (12) internally delimiting an exhaust volume; an exhaust gas inlet (16) opening into the exhaust volume; and an exhaust gas outlet pipe (18) communicating with the exhaust volume and having an outlet orifice (30) to the outside of the silencer (10), is characterized in that the outlet pipe (18) comprises a section (32) pressed against the casing (12), the casing (12) having at least one perforation placing the pressed section (32) in communication with the exhaust volume.
