Abstract: 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.

Abstract: 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°.

Abstract: The invention relates to a tank (1) for storing a liquid, comprising a wall (10) made of plastic and a device for stopping the filling of said tank (1) with a liquid at a maximum fill level, this device extending inside the tank (1) and comprising at least one opening (71) of which the position inside the tank (1) fixes the said maximum fill level. The device that stops the filling of this tank (1) comprises a first part formed with the wall (10) and a second part which is fixed hermetically to the first part.

Abstract: A container including an inner wall including an opening sealed by a plate of a technical module including at least one technical device, the sealing of the opening resulting from insertion of the plate into the opening in a main direction. The plate of the technical module includes a flange including a bearing surface, and the inner wall of the vessel includes a bearing directed towards the inside of the container, which acts as a seat for the flange, to block passage of the plate of the technical module through the opening towards outside of the container.

Abstract: 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: movement of the moving equipment in one of its sliding directions causes a passage to open into the chamber for passing the additive to the injection channel; and movement of the moving equipment in its other sliding direction creates suction within the chamber, which causes at least some of the additive contained in the injection channel to return into the chamber.

Abstract: 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.
