A charging housing or filler neck housing for insertion into a body opening in a motor vehicle comprises a housing body with a passage opening. A plug-in charging connector or a tank filler pipe can be inserted into the passage opening, and a sealing ring is arranged on the passage opening. The sealing ring has an annular sealing body, from which a first elastic sealing lip and a second elastic sealing lip extend, wherein the first sealing lip is designed to bear against a plug-in charging connector or tank filler pipe inserted into the passage opening, and wherein the second sealing lip is designed to bear against a closure flap closing the filler neck housing or charging housing.

Systems and methods for installing and sealing a fuel pump in a fuel tank are disclosed. In one embodiment, a system for installing and sealing a fuel pump in a fuel tank may include (1) a fuel tank with an opening in a surface thereof; and (2) a fuel pump hanger assembly, the fuel pump hanger assembly comprising; (a) a plurality of assembly screws; (b) a plurality of clamping lugs configured to thread onto the plurality of assembly screws and engage an inside surface of the fuel tank; (c) a top plate further comprising; (i) a bearing surface configured to engage an external fuel tank surface; (ii) a plurality of through holes proximate the perimeter of the top plate and perpendicular to the bearing surface; (iii) a plurality of bosses, each of the plurality of bosses adjacent to each through hole, configured to guide and position the each clamping lug; and (d) a gasket positioned between the top plate and the fuel tank.

A fuel tank for a generator or the like, wherein the fuel tank includes a rigid outer fuel tank structure and an inner bladder. The outer fuel tank structure includes a longitudinal channel for receiving the inner bladder. End caps are disposed on either end of the outer fuel tank structure, so that the internal bladder may be pulled therein with cables or the like. When the internal bladder needs to be replaced due to damage or corrosion, the end caps are removed and cables may be attached to one end of the damaged internal bladder for pulling it from the outer fuel tank structure. Additionally, a replacement bladder may be attached via cables to the other end of the damaged bladder, so that the replacement bladder is pulled into one end of the outer fuel tank structure while the damaged bladder is being pulled out the other end thereof.

In a vehicle lid seal structure, one of a housing and a lid is provided with an annular sealing member on a face facing the other. A cross-sectional structure of the annular sealing member includes a base portion and a lip portion. The base portion is attached to one of the housing and the lid. The lip portion extends from the base portion toward the other of the housing and the lid. The lip portion includes a connecting end between the lip portion and the base portion, and a free end that is an end portion opposite to the connecting end of the lip portion. Further, the lip portion is provided with a folding starting point between the connecting end and the free end. The folding starting point is provided for causing folding deformation of the lip portion toward a radially-outward side of the annular sealing member.

A container including an inner wall including an opening sealed by a plate of a technical module including at least one technical device, the sealing of the opening resulting from insertion of the plate into the opening in a main direction. The plate of the technical module includes a flange including a bearing surface, and the inner wall of the vessel includes a bearing directed towards the inside of the container, which acts as a seat for the flange, to block passage of the plate of the technical module through the opening towards outside of the container.

A quick connector of a fuel transfer line is provided. The quick connector is fastened to a fuel inflow/outflow nipple of a fuel transfer line and includes a connector casing that has a rear end to which a fuel inflow/outflow nipple is inserted and fastened. Additionally, a bypass cylinder is inserted into a front end of the connector casing in a linearly movable manner by hydraulic pressure of fuel and forms a flow path for a selective flow of fuel depending on a location within the connector casing.

To assist in maintaining a seal ring in a proper position in a fuel tank assembly, a retaining ring is utilized. The retaining ring surrounds the seal ring to provide a physical barrier to restrict the seal ring. The assembly includes a tank having an opening and a plurality of flanges located about the opening, a fuel pump module, the retaining ring and a seal ring. The retaining ring is located within the plurality of flanges, positioned around the opening and the fuel pump module. The seal ring is located within the plurality of flanges, positioned around the opening and the fuel pump module such that in a radial direction the seal ring is positioned between the fuel pump module and the retaining ring, and in an axial direction the seal ring is positioned between the fuel pump module and the fuel tank.

A method and system for forming a self-sealing volume includes an elastomeric composite structure. The structure includes layers of a cast polyurethane derived from a neat polyurethane monomer reaction mixture that does not substantially react at room temperature. The polyurethane monomer reaction layer includes a reaction product of an organic polyisocyanate and a reactive hydrogen-containing material reacted with a mixture of a monomeric polyol and polymeric polyols. The structure may further include one or more layers of a fabric that have been precoated with an aliphatic polyurethane, and one or more sealing layers. A fuel impermeable inner liner may be positioned in an inner region. The sealing layers may comprise at least one of partially vulcanized natural rubber (NR), polyisoprene (IR), styrene butadiene (SBR), or a blend of SBR with NR or IR. A dimensionally correct, self-sealing volume may be created by inflating the volume during its cure.

A closing plug for an opening in a body structure of an automobile, wherein the closing plug closes the opening against a passage of fluid and/or gas up to a limit pressure which acts on the closing plug, and allows a passage of fluid and/or gas above the limit pressure, characterized in that the closing plug comprises a base body consisting of a first plastic material, which has a holding section with holding means for holding the closing plug in the opening and a plate-shaped head section provided on one end of the holding section with at least one opening and that the closing plug comprises a sealing body of a second plastic material molded onto the base body in a plastic injection molding process.
