Definitions
- the invention relates to the technical field of anti-noise baffles (also called baffles) for vehicle tanks and motor vehicle tanks containing noise baffles.
- a fluid reservoir for a motor vehicle generally comprises several internal accessories such as a baffle or a sensor. These accessories are generally attached to the interior of this tank, on an inner surface of a wall of the tank.
- the deflector comprises two openwork panels interconnected by a central portion.
- the perforated panels are provided with holes to allow the fluid contained in the tank to pass through these holes.
- the central part of this deflector comprises complementary fixing means of a second fixing means arranged on the wall of the tank. It is therefore known to use a tank wall as a support for various internal accessories or as a support for intermediate internal accessories supports.
- the various internal accessories generate a relative size inside the tank. More particularly, the attachment of internal accessories on the tank wall considerably reduces the available area for attaching new accessories. The available surface on the tank wall is then insufficient to accommodate a new internal accessory. But more and more new functions are developed for motor vehicle tanks. It is therefore necessary to be able to integrate in a tank additional accessories ensuring these new functions. However, it becomes difficult to arrange new internal accessories for lack of available mounting surface on the tank wall. Furthermore, the establishment of fixing means on the wall of a tank is a delicate and expensive operation.

- the assembly comprises means for hanging on a support secured to a tank wall, thus maintaining the deflector attached to the tank.
- the invention also relates to a device comprising an assembly for a vehicle tank and an internal accessory for the tank, characterized in that the assembly is according to the invention, the internal accessory being carried by the portion forming support. This makes it possible to equip the tank with more internal accessories and thus to integrate into a tank additional accessories that can provide new or new functions developed for the tanks of a motor vehicle.
- the internal accessory can be chosen from:
- first accessory provided with second attachment means snap-fastenable in the first fastening means by translation interlocking in a first direction
- a second accessory provided with second snap-fastening means in the first fastening means by translation interlocking in a second direction, inclined or perpendicular to the first direction.
- the internal accessory can form an additional deflector. This makes it possible to equip the tank with more baffles and thus to further limit unwanted noise of fluid shocks against the wall of the tank.
- the internal accessory may comprise a sensor, for accurately measuring parameters such as temperature, pressure or concentration inside the tank.
- the invention further relates to a tank for a vehicle, characterized in that it is provided with at least one assembly according to the invention or at least one device according to the invention.
