Abstract: This invention relates to a device for injecting aqueous additives into an exhaust pipe of a motor vehicle, including an additive tank and a pumping module for taking the additive and directing it toward the exhaust pipe, characterized in that the pumping module includes a rotary electric pump (120) and includes a thermally conductive part (170) in contact with the casing of the pump (120) and the outlet of a pressure regulator (150) so as to transfer heat to said outlet of the pressure regulator (150).

Abstract: The present invention provides a suspension device for an electric pump of an assembly for drawing fuel in a motor vehicle, the device comprising: an outer support suitable for surrounding the electric pump, centered on an axis parallel to the axis of the electric pump, and adapted to be secured to the fuel-drawing assembly; and at least one resilient arm connected to the inside periphery of said outer support, which resilient arm extends essentially in a plane that is transverse to the axis of said outer support and possesses a shape such as to rest at least substantially tangentially against the body of the electric pump over a fraction of its length in order to support it at a distance from the outer support.
