A liquid container has a plurality of resilient liquid permeable bodies inserted via an aperture and attached to a mounting by a tether, so as to interrupt the free flow of liquid within the container and prevent noise and vibration resulting from the contained fluid sloshing. A method describes how the anti-slosh device can be installed into a liquid container and how the device can be retrofitted to any liquid container.

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.

A tank for transporting fluids on a truck chassis includes a front wall, side walls, a back wall, a top, and a floor. Interior stairs extend from the floor to an opening in the top to allow stair access into the interior with integrated safety handrails on the fill port cover. Stair toe kicks act as internal transverse baffles to help control fluid motion and surging. The stairs also act as a structural stiffener between longitudinal baffles. Horizontal baffles assist in controlling fluid motion and surging. Formed baffles provide strength and stiffness. A baffle interlocking system improves joint integrity and aids manufacturing. Formed outer skins provide structural strength for the tank. Ports located in front and rear bulkheads may be used for tank ventilation or, depending on local safety codes, as secondary access points. Doors or other access openings may be located in the tank bulkheads to provide better interior access.

A wave-eliminating plate securing structure in a fuel tank 1 includes: a wave-eliminating plate configured to be fixed to an inside of a resinous fuel tank and to suppress waving of fuel; and resinous clips each including a weld portion to be welded and fixed to an inner wall of the fuel tank, and an attachment portion to which to attach the wave-eliminating plate. After the clips are welded and fixed at their respective predetermined positions to an inner wall of the fuel tank in advance, the wave-eliminating plate may be inserted into the fuel tank, and attached and fixed to the clips. Thereby, the wave-eliminating plate can be easily fixed at a predetermined position to the inside of the fuel tank with high precision.

Disclosed is a non-metallic anti-explosion ball, comprising an equatorial ring (1), longitudinal sheets (2), a south-polar ring (41) and a north-polar ring (31). The equatorial ring (1) and the longitudinal sheets (2) are arranged perpendicularly. The south-polar ring (41) and the north-polar ring (31) are located on two sides of the equatorial ring (1) respectively. The south-polar ring (41) is located at one end of the longitudinal sheets (2), and the north-polar ring (31) is located at the other end of the longitudinal sheets (2). The equatorial ring (1), the south-polar ring (41) and the north-polar ring (31) are coaxial. A projection of the south-polar ring (41) is located inside a projection of the equatorial ring (1) in an axial direction of the equatorial ring (1), and a projection of the north-polar ring (31) is positioned inside the projection of the south-polar ring (41). Projections of the longitudinal sheets (2) extend from the projection of the north-polar ring (31) to the equatorial ring (1). A manufacturing process for the non-metallic anti-explosion ball is simple, and the production efficiency is high.

A tank system of a motor vehicle includes a volume modifying element, having a compensation volume, which is provided in the inner chamber of the fuel tank and which is used to equalize the vapor pressure. The compensation volume is connected to the surrounding area. The only connection between the volume modifying element and the surrounding area is formed by a storage unit of the gaseous fuel components and the inner chamber of the fuel tank is connected to the surrounding area by a valve unit. The valve unit is normally open when filling the fuel tank and when exceeding or falling below the pressure limits in the inner chamber of the tank, and is otherwise closed. The storage unit is connected to the valve unit. The volume modifying element and the valve unit are designed in such a way that vehicles which are parked for several days do not undergo diurnal losses due to changes in temperature of the surroundings, due to the fact that the vapor pressure equilibrium in the fuel tank can be maintained by the automatic supply and removal of ambient air in the, or from the, volume modifying element as long as the valve unit remains closed.

An anti-wave plate for a fuel tank includes a base plate. A first anti-wave part and a second anti-wave part are arranged on the base plate; the first anti-wave part includes first anti-wave plates and second anti-wave plates, and the first anti-wave plates and the second anti-wave plates are arranged in a crossed manner; the second anti-wave part is arranged on a side of the first anti-wave part, and the second anti-wave part includes anti-wave protrusions; and the base plate is further provided with a fixing part, and the fixing part fixes the base plate in a fuel tank.

A valve device for a fuel tank includes: a housing in which an opening is formed in a partition wall, and a fuel vapor discharge port is provided; and a float valve. A ventilation chamber is provided with a tubular wall that is configured to communicate with the fuel vapor discharge port, and a notch is formed in a lower portion of a tip portion in an extending direction of the tubular wall. The partition wall includes a ceiling wall in which the opening is formed, and a peripheral wall extends downward from a peripheral edge of the ceiling wall. A part of the peripheral edge of the ceiling wall and a part of the peripheral wall are positioned inside the tubular wall through the notch when viewed in an axial direction of the tubular wall and a valve axial direction.

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.
