摘要:
A wheel-shaped pressure-resistant vessel for storing gaseous, liquid or liquefied fuel and which has a substantially rigid shape. Specifically, the vessel contains a substantially continuous shell of a fiber-reinforced resin. The shell has a central opening, an inner lining and an axial reinforcement member. The shell has a substantial mechanical equilibrium shape such that the axial member is situated in a central opening. The axial member contains an inner member and two end plates, with each of the end plates fixing the shell to the inner member. Further, the axial member is attached, through both end plates, to the shell such that outer surfaces of the shell are pulled towards each other, thus reinforcing the vessel and maintaining the vessel, even while it is pressurized, in its wheel-like shape.

A seal assembly for a fuel tank having a tank opening therein includes an access cover adapted to close the tank opening. The seal assembly also includes a first seal made of a compressible material adapted to be disposed between the access cover and a tank surface of the fuel tank. The seal assembly includes a second seal made of a non-permeating material adapted to be disposed between the access cover and the tank surface. The seal assembly further includes an attachment plate for attachment to the tank surface and adapted to be disposed about the tank opening. The seal assembly includes at least one attachment fastener cooperating with the attachment plate to secure the access cover to the attachment plate and to seal the tank opening via the first seal and the second seal.
摘要:
A storage container for cryogenic liquids has an outer container and at least one inner container, an insulation space being situated between the outer container and the inner container or containers. The outer container and/or the inner container have devices for strengthening the container walls. The devices for strengthening the container wall of the outer container and/or of the inner container are constructed as at least one web arranged on the container wall of the outer container and/or of the inner container and/or as at least one supporting plate adapted essentially to the cross-section of the inner container.

A container assembly for transporting bulk materials that includes a molded, one-piece completely integral non-metallic container insert and a frame supporting the container insert. The container insert can be molded of polyolefin. It can include walls having varying thicknesses, a bottom wall having a thickness greater than the side walls, and/or reinforcing structures molded within the walls. The container assembly can be constructed to provide a fixed truck box or dump truck box.

The invention relates to an arrangement for a fuel tank for heavy vehicles. A middle section, which consists of plastic or aluminum material with an at least essentially identical transcurrent cross section in a horizontal direction viewed in the longitudinal direction, exhibits internal partitions extending horizontally in the longitudinal direction and bulkheads extending across the aforementioned partitions in the longitudinal direction. Pairs of end pieces forming end walls exhibit essentially the same profile as the circumference of the middle section and at least parts of the cross section of the partitions as end pieces which meet one another and middle sections for welding together at the respective ends of the assembled fuel tank. The partitions of the end pieces exhibit recesses forming connecting paths between the various formed sections in the middle section. Longitudinally extending recesses in the middle section are provided preferably for the purpose of receiving reinforcement and/or for suspending the fuel tank. The invention also relates to a process for the manufacture of the tank.
摘要:
A lower wall (8) forming a fuel storage chamber (5) becomes curved downward according to increase of the fuel amount, and at this time a support member (23) for supporting the fuel storage chamber (5) does not restrain the downward curvature of the lower wall (8), whereby the capacity of the fuel storage chamber (5) can be increased and whereby the amount of the fuel that can be stored in the fuel storage chamber (5) can be maintained at the maximum, as compared with structure inhibiting deformation of the lower wall (8).

摘要:
A fuel tank for motor vehicles is constructed so that the generation of noise in the fuel tank due to sloshing fuel is minimized. For this purpose, a dampener element, which is permeable to the flow of liquid fuel, is attached to the interior of the tank. According to the invention, the dampening element has a dimensionally stable lattice or similar network structure. This dampener element is attached near the bottom wall of the fuel tank and has a generally horizontal orientation.
摘要:
The present invention is directed to an opening structure of a fuel tank having a fuel tank wall made of plastic layers including at least an outer layer, an inner layer and an intermediate layer, with an opening portion formed to be integral with the fuel tank wall. The opening structure includes a cylindrical portion extended from the fuel tank wall outward thereof to form the opening portion, an overlapping portion extended from an end of the cylindrical portion to enlarge the diameter of the opening portion and bent at a bent portion to form an outer surface parallel with an opening end surface of the opening portion, and a compressed portion with at least a portion of the overlapping portion compressed in a direction perpendicular to the opening end surface of the opening portion. The opening structure further includes an annular member disposed around the opening portion to be in contact with the overlapping portion and the cylindrical portion, and at least a recessed portion for receiving therein a part of the outer layer to be integrally connected with the opening portion. The annular member has a step portion formed inward of the annular member in a radial direction thereof to contact with at least the compressed portion.
摘要:
A device for mounting a plastic fuel tank on the body of a motor vehicle with a carrier which is shaped to fit at least partially to the outer contour of the tank and at least one coupling disposed between the carrier and the tank. The coupling is releasably connected with a snap fit to the carrier and preferably is made of a thermoplastic material that is heat welded to the plastic tank.
