A work vehicle including: a drive device that has an internal combustion engine for driving a vehicle body; a first tank for storing fuel to be supplied to the internal combustion engine; and a second tank for storing fuel to be supplied to the internal combustion engine; wherein the first tank is disposed in front of or behind the drive device, and the second tank is disposed below the drive device so as to be separated from the first tank by a predetermined distance.

suction system for a liquid reservoir (3) it is provided, the reservoir being defined by side walls and a bottom wall (30), the system comprising one layer of permeable material (2), and the system it is characterized in that it comprises fastening means (21) for fixing said permeable layer (2) onto at least one wall (30) of said reservoir (3); suction means (1, 10, 16, 17) of said liquid arranged within said permeable layer (2); and connecting means (14, 41, 42) of said suction means (1, 10, 16, 17) to a suction duct for sucking said liquid; the arrangement being such that an internal volume (23) it is defined between said one layer of permeable material (2), said fastening means (21), and said at least one wall of said reservoir (30), wherein the liquid it is sucked into said internal volume (23) through said layer of permeable material (2) and through said suction means (1, 10, 16, 17).

A fuel tank includes an upper surface portion, a bottom surface portion, and a peripheral wall portion, and a weir portion vertically arranged at the bottom surface portion and causing a fuel in a predetermined amount to stay in a predetermined position of an inner portion when a vehicle body is inclined. The peripheral wall portion includes a first wall and a second wall which is perpendicular to and continuous with one end side of the first wall. The weir portion includes a first weir, a second weir, a third weir parallel to the first weir, a fourth weir parallel to the first weir and arranged between the first weir and the third weir, and a fifth weir interconnecting the third weir and the fourth weir.

A fuel-storage tank for a vehicle includes a body defining an interior volume having a floor and a ceiling and configured to store fuel. The tank further includes an anti-slosh reinforcement column extending between the floor and the ceiling. The anti-slosh reinforcement column has a vertical baffle extending between the floor and the ceiling. The vertical baffle has opposing first and second major faces and edges extending therebetween. A horizontal baffle of the column has upper and lower major faces and edges extending therebetween. The horizontal baffle is rigidly supported on the vertical baffle such that the first and second major faces are substantially perpendicular to the upper and lower major faces.

A composite tank for a reusable launch vehicle comprises a composite wall, having a first coefficient of thermal expansion. The composite wall comprises a first end, a second end, a central axis, which passes through the first end and through the second end, and a cylindrical interior surface. The composite tank also comprises slosh baffles, formed from a second material, having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion. Each of the slosh baffles is attached to the cylindrical interior surface of the composite wall. Each of the slosh baffles is annular and is separated from the cylindrical interior surface of the composite wall by a radial gap, selected, in part, based on a difference between the first coefficient of thermal expansion and the second coefficient of thermal expansion. The radial gap is configured to change responsive to changes in temperature of the composite tank.

The invention relates to an inlet structure of a reservoir pot, comprising a base plate, which can be arranged in an operating medium tank with the formation of a receiving volume below the base plate, and a plurality of first elements which extend from the base plate, wherein the first elements are at least partially spaced apart from one another, and operating medium can flow between the first elements into the receiving volume and can flow out of the receiving volume, wherein the first elements present a greater flow resistance in the outflow direction than in the inflow direction.

A storage tank for a gas is provided. The storage tank includes a liner defining an internal compartment; a boss coupled to the liner; an interlayer covering a portion of the boss and the liner, the interlayer being non-pyrolyzed and including an interconnected web and pores having a diameter greater than the diameter of a hydrogen molecule and less than or equal to about 2 nm; and an outer shell including a carbon fiber reinforced composite, the outer shell covering the interlayer, except for an interlayer end that is in contact with the boss, so that the interlayer end defines an interlayer ring that is exposed to an external environment. The storage tank is configured so that when gas diffuses through the liner to the interlayer, the interlayer channels the gas out of the exposed interlayer ring. Methods of fabricating the storage tank are also provided.

A process is disclosed for manufacturing at least one wall of a tank and comprises at least a first layer of thermoplastic and a second foam-based layer. The second foam-based layer forms at least part of an anti-slosh device, and the process is characterized in that the first layer and the second layer are molded in the same mold.
