The present invention provides a system (1) to prevent the formation of fuel vapors comprising a containment tank (10) and a variable volume tank (12) accommodatable within the containment tank (10), wherein the variable volume tank (12) is configured to receive liquid fuel. Our invention can be used in any tanks or reservoirs of liquid products that attack the ozone layer, preventing the formation of vapors that are extremely harmful to nature and the environment.

The invention relates to a fuel container (1) of thermoplastic plastics material having an upper base (2) and a lower base (3) which are supported against each other by means of at least one column-like support element (4), wherein the support element (4) is connected in a positive-locking manner and/or materially engaging manner to a wall (6) of the upper base on the one hand and to a wall (6) of the lower base on the other hand in such a manner that it can absorb tensile forces and/or pressure forces, wherein the support element (4) is constructed in several pieces and the support element is divided longitudinally and comprises at least two segments (8) which complement each other in cross-section and which form a common support face at the end side.

A wave eliminating plate 12 located within a tank shell 11 is provided with inflow ports 15A, 15B into which a fuel moving within the tank shell 11 flows and outflow ports 17A, 17B from which the fuel flowing from the inflow ports 15A, 15B flows in a different direction from an inflow direction. In addition, by inertia force due to the acceleration, deceleration, turning or the like of a vehicle, the fuel moving within the tank shell 11 is caused to change the flow direction while it flows from the inflow ports 15A, 15B of the wave eliminating plate 12 and flows out of the outflow ports 17A, 17B so that the fuel flowing out of the outflow ports 17A, 17B generates a vortex.

Disclosed is a grid-shaped fuel tank, which belongs to the field of vehicle parts. The grid-shaped fuel tank includes a fuel tank shell, wherein the fuel tank shell encloses a cavity comprising a fuel cavity, and the fuel tank shell comprises an upper shell area in an upper portion, a middle shell area in a middle portion and a lower shell area in a lower portion; the cavity is internally provided with a middle grid rib structure corresponding to a height area of a middle shell, the middle grid rib structure partitions a middle portion of the cavity into a plurality of middle grid cavities, the middle grid cavities do not communicate in a radial direction, and a bottom end of a first middle grid cavity group comprised in the middle grid cavities is provided with fuel passing ports for mutual communication to form the fuel cavity.

Disclosed is a urea tank and fuel tank assembly, which belongs to the field of automobile parts. The urea tank and fuel tank assembly includes a shell, wherein the shell includes an upper shell, a middle shell and a lower shell, the upper shell, the middle shell and the lower shell are welded separately to form a cavity including a fuel cavity. The urea tank and fuel tank assembly is welded after injection molding, so that not only is the shell uniform in wall thickness and high in mechanical strength, but also the welding stress is dispersed to the upper and lower ends of the shell by setting that the upper shell, the middle shell and the lower shell are welded separately, on the one hand, the stress concentration of the welded part of the shell is reduced and the cracking of the welded part is avoided.

A liquid tank including an internal network of cells. The cells are configured such that in use, movement of liquid between adjacent cells of the network of cells is prevented or retarded such that under conditions of liquid movement within the tank, kinetic energy transferred from the liquid to the tank wall is reduced as compared with the case where no cells are present. The tank is useful in the context of road tankers, for example, and can lessen the chance or completely prevent the vehicle from overturning on a corner due to shifting of the liquid load carried.

There is provided a fuel tank including: a fuel tank main body enclosed by a floor wall, side walls and an upper wall; and a separator including a strut, a first plate portion in which a first penetrating hole that penetrates in a plate thickness direction is formed, and a second plate portion in which a second penetrating hole that penetrates in a plate thickness direction is formed, the second plate portion sandwiching the strut with the first plate portion and extending in a diametric direction at an opposite side of the strut from a side thereof at which the first plate portion is disposed, wherein at least one of shapes, sizes or numbers of the first penetrating hole and the second penetrating hole is set to be different such that fluid resistances at the first plate portion and the second plate portion are different.

The invention relates to a method for producing a liquid container for a motor vehicle, having the method steps: providing a wall, which is provided in order to delimit an interior chamber of the liquid container for receiving a liquid; providing a structure, which is provided in order to be arranged in order to reduce sloshing noises in the interior chamber of the liquid container, wherein the structure comprises a random arrangement of threads cross-linked with each other and wherein a plurality of the threads of the structure are integrally joined, at least in sections, to at least one or more additional threads of the structure, such that a substantially monolithic structure is formed; connecting the structure to the wall.

A stiffness reinforcement device for a fuel tank of a vehicle may include a body including a pair of pillars formed at both lateral end portions of the body; an upper fusing portion molded to an upper part of the body integrally and fused to an upper plate of the fuel tank; and a lower fusing portion molded to a lower part of the body integrally and fused to a lower plate of the fuel tank.

A tank mounted on a working vehicle is provided with an exterior member including a first plate unit, a second plate unit, a third plate unit, a fourth plate unit, a fifth plate unit, and a sixth plate unit, a first baffle plate joined to a first inner surface of the first plate unit, a second inner surface of the second plate unit, and a third inner surface of the third plate unit, and a second baffle plate joined to a fourth inner surface of the fourth plate unit, a fifth inner surface of the fifth plate unit, and a sixth inner surface of the sixth plate unit.
