According to the invention said connecting device () comprises a tubular member () It provided to be inserted into the liquid tank (), said tubular member () having a first end portion () and a second end portion () provided to constitute a swirl pot (), and a flange () located on the external part of the tubular member (), a surface () of the flange () being provided to be welded to an external surface of a tank wall (), the connecting device () comprising a connecting means () on the first end portion () of the tubular member (), said first end portion () being located on the tubular member () relative to the flange () on the other side of the flange surface () provided to be welded to the liquid tank (), said connecting means () being provided for the fixing of the Liquid Delivery Module () to the tubular member (), the second end portion () of the tubular member () comprising an opening () provided to allow entry of the liquid in the tubular member (), the first end portion () comprising an opening () provided for the insertion of the Liquid Delivery Module ().

Connecting device between a liquid tank made of plastic material and a liquid delivery module on board of a vehicle

A fuel tank having two opposite wall portions and at least one reinforcing element connecting these two wall portions, such reinforcing element comprising at least two parts linked by at least one rotating link.

Fuel tank with improved creep resistance and method for manufacturing it

A gauging method for a plastic fuel tank mounted on a hybrid vehicle, the tank including a reservoir including a gauge for measuring an amount of fuel in the tank, the method including: measuring the amount of fuel in the tank using the gauge; estimating deformation of the tank using at least one sensor onboard the vehicle; and correcting the amount measured by the gauge based on the estimated deformation.

Gauging method for a plastic fuel tank of a hybrid vehicle

A process for manufacturing a fuel tank, including: inserting a plastic parison including two distinct parts into an open two-cavity mold; inserting a core inside the parison, the core including two parts of a reinforcing element capable of securing two different locations inside the parison; pressing the parison firmly against the mold cavities; fixing the two reinforcing element parts at the two locations of the parison using the core; withdrawing the core; closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; opening the mold and extracting the tank; making an opening into the tank wall; and through the opening, putting at least a third reinforcing element part to link/connect the two first parts together.

Process for manufacturing a plastic fuel tank

A fuel tank having two opposite wall portions and at least one reinforcing element connecting these two wall portions, such reinforcing element comprising at least two parts linked by at least one rotating link. A method for manufacturing such tank.

Process for reinforcing a plastic fuel tank comprising a wall defining an internal closed volume, according to which a structural member is fixed to the wall of the tank outside the closed volume, in at least two points being located in two different portions of said wall where a deflection induced when the tank is filled with fuel, is low; and said structure having at least one contact point with the tank wall in a portion of said wall where the deflection is high.

Process for reinforcing a rigid plastic fuel tank

A ventilation device including: a first enclosure including a first passage configured to be connected to a canister outlet and the atmosphere, and a normally closed shutter device configured to open to release the first passage; a second enclosure including a second passage configured to be connected to the canister inlet and a fuel tank, and a normally open shutter device configured to close to shut the second passage, the second passage being separate from and not in communication with the first passage; and a combined pressure/vacuum relief valve or OPR and UPR valve pair situated in or fastened to a bypass of the first passage configured to establish a connection between ends of the first passage when the shutter device is closed and when there is over- or under-pressure in the ends. A fuel system can include the device and a hybrid vehicle can include the fuel system.

Ventilation valve for a liquid tank comprising:

Valve for the venting circuit of a liquid tank

A plastic fuel tank including an upper wall, a lower wall and at least two compartments, such compartments being established by a dividing wall including a part of the tank upper and lower walls, this dividing wall having at least opening enabling free flow of liquids between the at least two compartments and at least opening enabling free flow of vapors between the at least two compartments, such openings occupying less than 80% of the dividing wall, the at least 20% remaining of the dividing wall being constituted by at least one kiss point formed by welding together a multiplicity of contact points of the upper and lower walls.

Plastic fuel tank with increased deformation stability

Liquid tank venting system comprising a chamber that is inside the tank and that is equipped with a drainage device that comprises at least one opening made in the chamber and an elastomer-based non-return valve capable of sealing/freeing this opening, according to which this non-return valve is forced into a position for leaktight closure of the opening via a specific device starting from a certain liquid level in the tank.

Liquid tank venting system

Valve for the venting circuit of a liquid tank, the valve comprising a chamber which includes openings that allow liquid to penetrate into the chamber above a certain level in the tank and/or in the event of waves in the tank or the tank being turned upside down, a cover for the chamber including an aperture that is susceptible to open into the venting circuit of the tank, and a float comprising a body and a needle that close off the aperture, the float being able to slide vertically inside the chamber depending on the level of liquid therein, the needle of the float being frustoconical-shaped and based on an elastomeric material.

Valve for the ventilation circuit of a liquid tank, comprising:

A device for a venting circuit of a liquid tank provided with a canister and a filling tube including a filling head, this device comprising: a) a control chamber that communicates with: 

Device for the venting circuit of a liquid tank and valve incorporating said device

A valve for the venting circuit of a liquid tank including a main chamber which opens into the tank and is connected via an aperture to the venting circuit, a float comprising a body, and a head capable of closing off the orifice. The float being able to slide vertically inside the main chamber. The valve further including a baffle surrounding the aperture and defining a secondary chamber via the bottom inside the main chamber. The dimensions and the shape of the secondary chamber, of the body of the float, and of the head of the float are designed so that the head can slide at least partly inside the secondary chamber, while the body of the float cannot do so.
