The reservoir tank includes a reservoir body which reserves a fluid in an inner portion thereof formed to be in a hollow box shape. The reservoir body includes a port extending outward, a reservoir chamber which reserves the fluid and a port chamber which volume is smaller than that of the reservoir chamber and is in fluid communication with the port and a first communication passage positioned at a portion lower than a changeable liquid surface of the fluid reserved in the reservoir chamber in a vertical direction and provided at the first partition portion to allow the fluid communication between the reservoir chamber and the port chamber and wherein the port chamber and the port are kept being a state in which they are filled with the fluid supplied from the reservoir chamber via the first communication passage.

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 fuel tank and a method for producing a fuel tank for a motor vehicle. The fuel tank is designed as a blow-molded hollow plastic member, into the interior of which a functional component support is introduced. The support, to which functional components, such as a fuel pump, a level indicator or valves can be secured, includes at least one supporting leg to be supported on an inner face of the hollow plastic member delimiting the interior thereof. The supporting leg of the functional component support is designed to include a connection point to which a functional component can be connected.

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.

Various techniques are provided for an energy absorbing fluid bladder. In one example, the fluid bladder includes a bladder body and a perforated baffle structure. The perforated baffle structure can be disposed within the bladder body and configured to mitigate a pulse of fluid (e.g., fuel) moving within the bladder body before the pulse reaches the bladder body. Related methods are also disclosed.

The present invention relates to a plastic tank which provides storing of gasoline and urea liquid called adblue, used in automotive industry, particularly in vehicles which operate with gasoline and which reduces the damage of vehicles, which operate with gasoline, to the environment, in a single tank with two chambers, and relates to a special core heating system designed for production of this tank by using rotation technology.

Methods and systems are provided for a baffle system of a fuel tank. In one example, a baffle system for a fuel tank may include a horizontal section and a vertical section, where the vertical section is arranged perpendicular to the horizontal section and includes a first end coupled to the horizontal section. The vertical section may be rigidly attached to a top surface of the fuel tank via an attachment interface.

The mounting structure of a fuel device is for mounting the fuel device, which includes a plurality of components, on a baffle plate for suppressing waving of liquid fuel stored in a fuel tank. One of the components of the fuel device is integrally formed, as a mounting portion, with the baffle plate. The remaining components of the fuel device are mounted, as a mounted portion, on the mounting portion of the baffle plate.

The present disclosure is directed to a fuel tank with an internal support structure and external reinforcements to minimize deformations due to pressure variations, such as may arise from diurnal temperature variations. Uncontrolled contraction of fuel tanks may result in undesirable reductions of tank volume, and uncontrolled expansion of fuel tanks may result in unwanted collision of fuel tanks with other vehicle components. The fuel tank of the present disclosure may find utility in applications where regular venting of fuel tanks is not practical, such as in hybrid vehicles.

A fuel tank (10) includes: a lower panel (12) made of steel and an upper panel (11) made of steel; and at least one pillar (100) made of steel which is disposed in an interior space (V) formed by the lower panel (12) and the upper panel (11) facing each other and of which a first end portion is fixed to the lower panel (12) and a second end portion is fixed to the upper panel (11) in a state where the second end portion is disposed in a hole formed in the upper panel (11).
