A motor vehicle operating fluid container is made of thermoplastic. The container is composed of two shells forming a substantially closed hollow body. A first shell forms an upper base of the container, and a second shell forms a lower base of the container. The container includes at least one line which is designed as an integral part of a container wall over at least one sub-length, where the line is designed as a channel which runs in the container wall over said sub-length. The channel has an open trough-shaped profiled cross-section which forms a part of the line cross-section, and the channel is closed by at least one cover which complements the trough-shaped profiled cross-section so as to form a closed cross-section.

Fluid containers to evacuate spilled fluid from the interior of an enclosure of the fluid container are disclosed. An example system includes an enclosure and a fluid container within the enclosure. The fluid container includes a fluid capture area at a top of the fluid container and a channel at a side of the fluid container. The fluid capture area directs the fluid to the channel, and the channel directs the fluid from an interior of the enclosure to an exterior of the enclosure

A non-metallic fuel tank includes a non-metallic tank body, at least one coupling device or mounting system for coupling the non-metallic tank body to a bed of a truck or to a trolley, and a fuel fill opening. A grounding wire may be coupled to the non-metallic tank as well as a fuel line connector which is also coupled to the existing fuel system of a truck. A mounting system for a non-metallic fuel tank includes two rear toe clamps and two front mounting assemblies which include a front mount base and an angle iron coupled together. A portable fuel tank includes a non-metallic tank body and a trolley coupled to the tank body. The trolley includes a base, a mounting system for coupling the non-metallic tank body and the base, at least one handle and at least one wheel.

A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.

A fuel tank according to technology disclosed herein includes: a fuel tank main body that is made from resin, that stores fuel internally, and that is formed with a protruding attachment pin at a tank inner side; an in-built component installed inside the fuel tank main body; a fixed attachment portion that is provided at the in-built component, and that is fixed to the fuel tank main body; and a movable attachment portion that is provided at the in-built component, that is formed with a connecting portion formed with an attachment hole into which the attachment pin is inserted and anchored, and that is formed with a deformable portion having an end portion in the attachment hole abutting or facing the attachment pin, wherein the deformable portion is capable of expanding and contracting along an expansion and contraction direction of the fuel tank main body.

A liquid container for a motor vehicle, comprising a storage volume for storing a liquid and comprising at least one shell, which at least partially delimits the storage volume, wherein the shell has been produced at least partially in an injection molding process, the shell has a barrier film, the shell has a reinforcing element, which is formed at least partially or completely of a thermoplastic fiber-reinforced composite material, the shell has a single-part or multi-part support structure, which is formed at least partially or completely of an injection-molded material, the barrier film is integrally bonded to the reinforcing element, and the barrier film and the reinforcing element are each integrally bonded to the support structure.

A fuel tank system is obtained, in which internal pressure does not readily increase and in which there is no need to secure a space for deformation at the periphery of the fuel tank. A vapor pipe is connected to a fuel tank, and an atmosphere release pipe is connected through a canister. An electromagnetic valve is attached to the vapor pipe, communicating a gas layer at an upper portion inside the fuel tank with the external atmosphere by opening the electromagnetic valve. A thinned deformation location capable of indentation-deformation towards the inside is provided at an upper wall portion of the fuel tank. A negative pressure pump is provided to reduce the pressure inside the fuel tank, causing the deformation location to indentation-deform towards the inside. The fuel tank is sealed by closing the electromagnetic valve in a state in which the deformation location is indentation-deformed towards the inside.

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.

Provided are a fuel tank made of polyketone and a method of manufacturing the same. The method includes injection-molding an upper cover and a lower cover using an injection-molding machine, placing the upper cover and the lower cover at a relatively high position and a relatively low position, respectively, assembling the upper cover and the lower cover with each other, and bonding contact surfaces between the upper cover and the lower cover to each other using a laser beam. Since the upper cover and the lower cover are formed at the same time and are bonded to each other immediately after being assembled by a machine, it is possible to achieve automated production, mass production and remarkable cost reduction. Further, since the fuel tank has sufficient rigidity due to the rigidity of polyketone without an additional reinforcing member, it is possible to manufacture a lightweight fuel tank.
