The invention relates to an attachment device () for a module for dispensing an aqueous solution contained in a tank on board a motor vehicle. According to the invention, such an attachment device () comprises a pump stator (), a heating means and a heat diffuser () which comprises a base () and a first plurality of walls () that are substantially vertical with respect to said base () and define at least one first internal volume (), said base () and/or at least one wall that is substantially vertical with respect to the base () comprising at least one means () for positioning the pump stator and/or a first means () for attaching the pump stator and/or at least one second means () for attaching the heating means, the pump stator () and heat diffuser () assembly being overmolded with a plastic material, the attachment device () comprising at least one first through-hole (), preferably in the region of the base of the attachment device (), suitable for discharging the aqueous solution pumped by the pump, and a second through-hole () suitable for supplying the pump with aqueous solution.

Attachment device for a module for dispensing an aqueous solution contained in a tank on board a motor vehicle

A system for injecting an aqueous solution into an injection engine, includes: a tank for an aqueous solution, a circuit for supplying aqueous solution to the tank and a filter for filtering the aqueous solution, and a circuit for recirculating the aqueous solution. The injection system also includes recirculation of the aqueous solution, and is provided with an electrovalve including a first inlet connected to a filler neck of the tank, a second inlet connected to the recirculation circuit, and an outlet connected to the supply circuit. The filtration filter is arranged in the supply circuit and/or in the recirculation circuit.

System for injecting an aqueous solution into an injection engine

A process is disclosed for manufacturing at least one wall of a tank and comprises at least a first layer of thermoplastic and a second foam-based layer. The second foam-based layer forms at least part of an anti-slosh device, and the process is characterized in that the first layer and the second layer are molded in the same mold.

Method for the production of a plastic tank comprising an anti-slosh device

A vehicle system storing an aqueous solution includes: a first compartment; a second compartment; a module that includes a feed pump unit connected for pumping aqueous solution from the first compartment to a feed outlet; and a jet pump having a suction inlet, a pressure inlet and an outlet. The feed pump unit is further connected for pumping aqueous solution along a flow path from the first compartment through the feed pump unit, through the pressure inlet of the jet pump to the outlet of the jet pump. A heater heats the flow path. The suction inlet is connected to a suction line that receives the aqueous solution from the second compartment. The outlet of the jet pump returns aqueous solution from the suction inlet and from the pressure inlet to the first compartment.

System for storing an aqueous solution on-board a vehicle

A container including sealed walls for containing a liquid, one of the walls forming a container bottom, the container bottom including a plurality of partitions defining therebetween areas contained consecutively inside one another, each of the areas communicating with an adjacent contained area via a passage including a threshold. The threshold of the passage between one area and an adjacent contained area is a low point of the area and a high point of the adjacent contained area, for any given area. The passage between the given area and the area in which the given area is contained, and the passage between the given area and the area contained within the given area are arranged in angular sectors defined by imaginary geometric angles opposed at the vertex thereof, the vertex being located in line with a lower-level area of the container, the angles having a size of less than 45&#xb0;.

Container comprising a liquid trap

The invention relates to a tank () for storing a liquid, comprising a wall () made of plastic and a device for stopping the filling of said tank () with a liquid at a maximum fill level, this device extending inside the tank () and comprising at least one opening () of which the position inside the tank () fixes the said maximum fill level. The device that stops the filling of this tank () comprises a first part formed with the wall () and a second part which is fixed hermetically to the first part.

Tank with ventilation canal comprising cover

There is provided a system for storing and injecting an additive into exhaust gas from an internal combustion engine, the system comprising a tank for storing the additive, an injector, and a pump for driving the additive from the tank to the injector via an injection channel, the system also comprising a purge device mounted between the pump and the injection channel. The purge device comprises a chamber and piston moving equipment slidably mounted in the chamber, the purge device being designed so that:

SCR system and a method of purging it

A process for manufacturing a plastic fuel tank including: introducing a parison into mold cavities; introducing a core inside the parison, where the core is first fitted with a swirl pot having a housing for the pump; closing the mold so that the cavities come into leaktight contact with the core; pressing the parison against the cavities by blowing through the core and/or applying a vacuum behind the cavities; fastening the swirl pot to the parison using a device attached to the core; molding the parison by blow molding and/or thermoforming; unmolding the tank, and mounting a pump in the housing of the swirl pot. The mounting of the pump is achieved by way of an intermediate part, the external shape of which is standard and complementary to that of the housing, and the internal shape of which is adapted to the pump.
