Abstract: An after-treatment exhaust gas mixer for mixing the exhaust gas with a reducing agent, such as a diesel exhaust fluid for selective catalyst reduction, comprises a mixing chamber through which the exhaust gas circulates, from an inlet to an outlet, and a reducing agent sprayer, able to spray a reducing agent into the mixing chamber. The mixing chamber comprises a pipe that is rectilinear along an axis and the sprayer is positioned in the upstream part of the rectilinear pipe and oriented so as to spray in the downstream direction substantially parallel to the axis.

Abstract: A valve comprises a flap, a tubular valve body defining an exhaust gas flow passage, and a device to guide the flap relative to the valve body to allow the flap to pivot relative to the valve body around a pivot axis between a closing position and a freed position of the exhaust gas flow passage. The flap has two large faces substantially parallel to one another and connected to one another by an edge of the flap. The guide device comprises a pin, a distal, end and a base. The valve also comprises a stabilizing member secured to the flap.

Abstract: The valve includes a valve body that inwardly defines a passage for circulation of a fluid, a drive shaft, and a bearing to guide the rotation of the drive shaft. The bearing comprises a chamber surrounding a segment of the drive shaft and a plurality of balls filling the chamber. The balls are free inside the chamber, and the chamber is completely filled with balls. The balls are in contact with the drive shaft along all or part of the segment.

Abstract: A valve comprises a body having a gas inlet and outlet, a flap in the body,—a drive shaft which is rigidly connected to the flap, an actuator having a motor shaft, and a coupling of the motor shaft and the drive shaft. A mounting for the actuator on the body comprises a side wall defining a cavity and closed in part at angular sectors facing towards the inlet and towards the outlet. The wall has openings for circulating air between the inside and the outside of the cavity. A thermally insulating partition is between the body and the actuator and has a surface area which is greater than 50% of a cross section of the wall taken in a plane which is perpendicular to the axis of the shaft, and has an opening for receiving the shaft with a gap. A plate is connected to the shaft, which is axially interposed between the partition and the actuator, and covers the gap.

Abstract: A valve comprises a valve body, a flap, and a shaft driving the flap. At least one first bearing guides a first end of the shaft. The first end of the shaft includes an inner housing emerging axially. The first bearing includes a barrel axially engaged in the inner housing, such that no accumulation of condensates can occur in the inner housing when the first end of the shaft points downward.

Abstract: A heat recovery device extends between an inlet and an outlet for exhaust gas, and includes a valve delimiting a direct passage for gas between the inlet and the outlet. The valve comprises a valve body housing a gate movable between a closing off position and a released position. A heat exchanger has an exchanger inlet upstream of the gate and an exchanger outlet downstream of the gate. The valve comprises a tube partially extending inside the valve body up to a mouth edge at a distal end, with the mouth edge extending in a plane. The gate has a plane contact surface configured to come in a direct contact with the mouth edge when the gate is in the closing off position.

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.
