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 device includes a power source, at least one exhaust gas purification member having an upstream face and a downstream face, and a heating member placed in front of and at a distance from the upstream or downstream face. The heating member comprises a frame and a plurality of elongate heating elements surrounded by a peripheral part of the frame. Each heating element has first and second ends, with at least one of the first and second ends being electrically connected to the power source with the other end being connected to the frame. Each heating element is, between the first and second ends, connected only to at least one other of the heating elements. The heating elements are in contact with one another by respective points of contact, two points of contact of two different heating elements in contact with one another being at the same electric potential.

Abstract: An actuator includes a slider intended to actuate a gate, movable between first and second positions, and an urging member to apply an urging force to drive the slider towards a first position when a temperature of the urging member is greater than a predetermined value. The actuator includes an elastic member that applies on the slider a return force towards a second position. The return force is less than the urging force. The urging member is a helical member with shape memory, and is ductile when its temperature is less than the predetermined value, and is formed towards a predefined helical shape when its temperature is greater than the predetermined value.

Abstract: A heat recovery device comprises a valve body inwardly defining a direct flow path for exhaust gases from an inlet to an outlet, a heat exchanger comprising a flow passage for the exhaust gases emerging in an inlet zone of the valve body, and a gate positioned in the valve body. The heat recovery device comprises a guide wall positioned in the direct flow path at the inlet zone, arranged to guide the exhaust gases from the inlet toward the cutoff section away from the inlet zone when the gate frees the direct flow path, and delimiting at least one orifice to allow the exhaust gases to go to the inlet zone when the gate closes off the direct flow path.

Abstract: An exhaust line element comprises a valve body, a shutter, a pivot link connecting the shutter to the valve body, an upstream tube, and a downstream tube. At least one first stopper is attached on an inner surface of the valve body. The shutter abuts against the first stopper in the closing off position. The first stopper defines a longitudinal position of at least one of the upstream tube and the downstream tube relative to the valve body.

Abstract: An ammonia storage cartridge includes an ammonia storage member having a storage material capable of absorbing or adsorbing ammonia. The storage member extends along a longitudinal axis. A heating element heats the storage member, and a hermetic tank houses the storage member. A tubular ammonia circulation element is arranged coaxially to the storage member, and includes a first surface at least partially delimiting, with an element chosen from among the heating element and the hermetic tank, a circulation duct for the fluid ammonia. A second surface is arranged at least partially in contact with the storage member, and at least one orifice passes radially through, allowing the circulation of fluid between the circulation duct and the storage member.

Abstract: An exhaust line includes a spiral heat exchanger having a first passage for a first fluid and a second passage for a second fluid. The second passage is arranged in a manner such that the second fluid circulates from an inlet firstly in at least one first circumferential segment disposed in a proximity of a first axial end and then into a plurality of second circumferential segments shifted towards a second axial end relative to the first circumferential segment. The second fluid advances axially in a counter current flow against the first fluid towards the first axial end while passing from one second circumferential segment to the next.
