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.

The invention relates to an operating-fluid container (1) for a motor vehicle, comprising a container body which is assembled from two mutually complementary injection-molded shells (2a, 2b) which consist of thermoplastic material and are welded together in an encircling manner to form a substantially closed hollow body, wherein at least one shell (2a, 2b) is at least in regions formed from thermoplastic materials having different strengths, wherein at least one part-region consists of a thermoplastic material having a fibrous filling, wherein the shell (2a, 2b) has been obtained by way of a co-injection process during injection molding.

Liquid reservoir systems are disclosed. In one embodiment, a liquid reservoir system may capture and retain a fuel reservoir to provide an uninterrupted fuel supply to a fuel pump or pickup line during low fuel conditions such as those that may be experienced during vehicle acceleration, braking or side to side maneuvers. It may also capture and retain a fuel reservoir to provide an uninterrupted fuel supply to a fuel pump or other pickup line during periods of high agitation such as may be experienced during vehicle jumping, cross country/closed course racing and other aggressive driving maneuvers.

The invention relates to an operating fluid tank (1) for a motor vehicle, comprising a tank body which is composed of two mutually complementary, injection-molded shells (2) which are made of thermoplastic material and which are welded circumferentially to one another to form a substantially closed hollow body, wherein at least one shell (2a, 2b) is formed at least in certain regions from thermoplastic materials of differing strength and/or elasticity, wherein at least one partial region is formed from a thermoplastic material which is elastically deformable, and wherein the shell (2a, 2b) has been obtained by a co-injection process during injection molding.

Methods and systems are provided for regulating fuel flow in a fuel tank. In one example, a method may comprise fueling a fuel tank by receiving a nozzle into a filler tube which extends into a fuel tank to fuel the fuel tank, and directing fuel through the tube against vanes in a baffle which forms a compartment within the tank. Additionally, the method may comprise enabling the vanes to open so that pressure within the compartment remains below a level which would otherwise cause shut off the nozzle during the fueling.

A pump module is disposed on a bottom portion of a fuel tank in the fuel tank. The pump module includes a suck-up unit for sucking up a fuel and a plurality of engaged portions. A bracket includes a base portion, a plurality of engaging portions, and a flow path. The base portion is a frame member fixed to the bottom portion and surrounding the pump module in a state where a lower end portion is in contact with the bottom portion. The engaging portions protrude from the base portion toward an upper side of the fuel tank and are respectively engaged with the engaged portions of the pump module. The flow path is disposed in the base portion and allows an inside of a frame of the base portion and an outside of the frame of the base portion to communicate with each other.

A fuel tank includes: a tank body including a bottom wall, a lateral wall and an upper wall, the tank body storing fuel in an interior surrounded by the bottom wall, the lateral wall and the upper wall; and a sub-tank storing a part of the fuel, the sub-tank including a wall portion, an opening portion and a post portion, the wall portion standing on the bottom wall and extending toward the upper wall. The opening portion is provided in the wall portion and is a portion in which the fuel flows. The post portion is provided integrally with the wall portion. The post portion is extended along a height direction of the wall portion from the bottom wall and is joined to the bottom wall and the upper wall.

A fuel tank has a welded member that is welded inside a fuel tank body. The welded member includes a welded face that is welded on at least one of a first tank face and a second tank face which faces the first tank face, of the fuel tank body, and wherein the welded face includes a facing side in a concave shape that faces a given point determined based on a displacement of distance between the first tank face and the second tank face when the fuel tank body receives an internal pressure.
