A plastics container of modular construction includes a first plastics segment and a second plastics segment. The first and second plastics segments are connected to one another by plastics welding. At least one of the first and second plastics segments has a paintable surface layer on an outer side thereof or is comprised of a paintable material.

An operating fluid container for a motor vehicle for accommodating an operating fluid. The operating fluid container has a compensation container that is at least indirectly fluidically connected to the atmosphere (ATM). The operating fluid container has the following features: the compensation container is situated within the operating fluid container in such a way that an outer surface of a compensation container upper shell is situated opposite from an inner surface of an operating fluid container upper shell; in the event of positive pressure in the operating fluid container relative to the atmosphere, a compensation container volume decreases; and in the event of negative pressure in the operating fluid container relative to the atmosphere, the compensation container volume increases. The operating fluid container is characterized in that the compensation container upper shell opposite from the operating fluid container upper shell has a shape, at least in sections, that is complementary to the operating fluid container upper shell.

A support assembly type baffle is proposed. The baffle may include a baffle body provided in an inner space of a vehicle tank to reduce flow noise, and having a plurality of through holes spaced apart from each other and a fastening portion formed on the inner circumferential surface of the through holes, and a support having a columnar shape, being fitted into the through holes to penetrate the through holes, and having an engagement portion coupled with the fastening portion, formed on the outer circumferential surface thereof, so that the support is fastened to the baffle body in a state of penetrating the baffle body, each of both ends of the support being fixed to two opposite sides of the inner sides of the tank to maintain the shape of the inner space of the tank.

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.

A method for producing a plastic tank having one or more reinforcements. The method includes forming at least one part of the tank wall with a semi-finished panel made of plastic having at least one outer layer composed of a first thermoplastic, forming a reinforcement for the tank wall with at least one fibre-reinforced structural component comprising a matrix composed of a second thermoplastic that is weldable to the first thermoplastic. The fibre-reinforced structural component is then applied to a predefined region of the at least one outer layer of the semi-finished panel. The fibre-reinforced structural component is then fused with the outer layer of the semi-finished panel by applying heat to the semi-finished panel and the applied fibre-reinforced structural component. The fused fibre-reinforced structural component and semi-finished panel is then formed into a final shape. Optionally, the formed component is then connected to at least one other part of the tank wall to form the complete tank wall.

It is proposed a tank manufactured from a plastic material. The tank comprises a reinforcement member. The reinforcement member comprises a first portion made of a first material weldable to the plastic material of the tank; and a second portion made of a second material having a tensile stress at break which is three to nine times larger than the tensile stress at yield of the first material. The second portion comprises at least one through-hole, and the first material extends in said at least one through-hole and at opposite sides of said second portion adjacent said at least one through-hole.

A liquid tank having a tank interior space delimited by a tank wall and fillable with liquid, a withdrawal opening; a retention component that delimits a component interior region in the tank interior space; the component volume of the interior region being less than the tank volume; a partition of the retention component permitting a flow of liquid, out of a component exterior region located outside the interior region but inside the tank volume, through the partition into the interior region and presenting a flow resistance to a flow out of the interior region through the partition into the exterior region, in such a way that the partition exhibits a liquid retention capability with respect to surging movements of liquid in the interior region; the withdrawal opening being arranged in such a way that at least as soon as a level falls below a threshold, the partition is arranged between the withdrawal opening and a liquid quantity received in an exterior region of the tank interior space; the retention component is flowthrough-capable at least in portions only unidirectionally from the exterior region into the interior region, but not in the opposite direction.

The invention relates to a filler pipe (1) weldable to a liquid tank (3) of a vehicle, wherein the filler pipe comprises a main body (4), a secondary body (5) configured to support an inlet check valve (2) and a weldable flange (6) suitable for welding around an opening in the liquid tank (3), the weldable flange (6) extending between the main body (4) and the secondary body (5).

A check valve for fuel tank comprises a joint that is fixed to a fuel tank, a passage forming part, and a valve member. The joint is connected to one end of the passage forming part, and an outlet is formed at the other end of the passage forming part. The valve member that opens and closes the outlet. The valve member comprises a valve element, a spring bearing part, a holding part continuous to at least one of the joint and the passage forming part, and a compression coil spring. The joint and the passage forming part are communicated to each other to form a fuel passage. At the end on the joint side of the passage forming part in the fuel passage, there is formed a diameter enlarged portion having an inner diameter gradually increasing from a fuel supply pipe side toward the outlet side.

A reinforcement structure made of plastic material for plastic vehicle tank. The reinforcement structure has a first portion comprising at least one weak section and at least one strong section, which are designed so that the weak section breaks before the strong section, when the first portion is under mechanical stress, the reinforcement structure also has at least one second portion designed to reduce the slosh noise, the second portion extends from the strong section.
