A device for fastening tank insert parts, wherein the device has a holding element for holding the tank insert part and at least one elastically deformable clamping device which is connected to the holding element and by means of which a fastening structure can be received. Furthermore, a plastic tank having a fastening structure which is arranged in the interior thereof, and having a device according to the invention which is arranged thereon for fastening tank insert parts.

An assembly for a fluid tank includes a baffle and a fluid transfer line. The baffle includes a first deflecting surface defining a first part of the tank and a second deflecting surface defining a second part of the tank. The fluid transfer line extends from the first part to the second part and is linked to the baffle by a linkage supported by the assembly. The extension of the fluid transfer line in the first part defines a first portion of the fluid transfer line, and the extension of the fluid transfer line in the second part defines a second portion of the fluid transfer line. The linkage allows for simultaneous rotation of the first portion and the second portion of the fluid transfer line towards a surface including one of the deflecting surfaces.

A fuel tank unit includes a lid member configured to close an opening formed on a fuel tank. The fuel tank also includes an upper unit attached to the lid member and including a combination valve device configured to be introduced into the fuel tank via the opening formed on the fuel tank and configured to function as an evaporated fuel control valve and a full limit valve. The lid member includes a cylindrical protective case configured to protect the combination valve device of the upper unit when the combination valve device is introduced into the fuel tank via the opening. The protective case is configured to entirely enclose an outer circumferential surface of the combination valve device with a space therebetween.

There is provided a fill-up restriction valve including: a housing; and a float valve. The housing includes a housing body including a body-side peripheral wall, and a lower cap including a cap-side peripheral wall, the lower cap being installed to a lower side of the housing body by a joint portion. The joint portion includes an annular groove, an insertion wall portion, and an annular protrusion formed on one of the insertion wall portion and the annular groove, or an annular seal member disposed between the insertion wall portion and the annular groove. The annular protrusion or the annular seal member is configured to be in pressure-contact with the annular groove and the insertion wall portion in a state where the insertion wall portion is inserted into the annular groove.

There is provided a valve device, including: a housing; a float valve; and a seal member. An opening portion includes a first region, and a second region. The seal member includes a first cover portion, and a second cover portion. The second cover portion includes a support portion, a wide portion, and a narrow portion. In a state where the seal member is retained and supported by the support portion with respect to the float valve, a width of the wide portion is set such that a tip end of the second region is covered, and that the second region of the opening portion is not exposed out of the seal member even in a state where the seal member is maximally displaced in a radial direction and/or a peripheral direction of the housing with respect to the opening portion.

An assembly for mounting at least one component in a tank for a motor vehicle, the tank including a wall portion and an attachment portion projecting outward from the wall portion, the attachment portion defining an opening in the wall portion, the assembly including: a mounting module configured to carry the at least one component and to close the opening in the wall portion; the mounting module including an outer side configured to be accessible from outside the tank; at least one connector arranged on the outer side of the mounting module, the at least one connector being connected to the at least one component; a clamp configured to clamp the mounting module to the attachment portion; and a cover attached to the clamp and covering at least partially the at least one connector.

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.

A valve case mounting structure includes a mount base and a valve case. The mount base includes a valve case support portion and a retainer piece having a first engagement opening and a second engagement opening. The valve case includes an engaging projection portion, and a holder portion. When the engaging projection portion is positioned at a front end side of the first engagement opening, the retainer piece does not reach the holder portion. When the engaging projection portion is moved from the front end side of the first engagement opening toward the second engagement opening, a front end portion of the retainer piece is inserted into the holding space before becoming unable to be inserted into the holder portion.

A fuel pump module includes: a pump unit; a lid provided to close an opening of a fuel tank; and a flexible fuel tube. The pump unit includes a fuel pump configured to pump fuel out of the fuel tank, a housing that holds the fuel pump, and a filter configured to filter the fuel. The lid has a discharge port to supply the fuel to outside of the fuel tank. The flexible fuel tube connects the pump unit and the discharge port. The housing includes a guide portion configured to fix the pump unit to a fixing member having a pair of rails provided in the fuel tank, and a separation regulating member configured to regulate the guide portion from separating from the pair of rails by engaging with the fixing member.

A fuel tank and a method for producing a fuel tank for a motor vehicle. The fuel tank is designed as a blow-molded hollow plastic member, into the interior of which a functional component support is introduced. The support, to which functional components, such as a fuel pump, a level indicator or valves can be secured, includes at least one supporting leg to be supported on an inner face of the hollow plastic member delimiting the interior thereof. The supporting leg of the functional component support is designed to include a connection point to which a functional component can be connected.
