A refuelling coupling has an annular fitting 101 having a bore 102, bayonet lugs 103 and slots 104 suiting it for connection to a pressure filling nozzle. A flange 122, drilled with screw holes for securement to a fuel tank (not shown), extends out from the fitting 101. Also not shown for the sake of clarity is a tube extending own from the flange. Rods extend down from the flange 122 to a spider 125, with springs bearing upwards onto the underside of a dry-break member 105, through which the rods extend. The rods, springs and spider are within the non-shown tube.

On attaching and opening of a pressure filling nozzle to the coupling, the dry-break member 105 is displaced resiliently inwards fuel can flow past this member and into the tank.

The dry-break member has a central aperture 111, normally closed by a plug 112, which is threaded externally 114 and carries an O-ring seal 115 above the thread. The central aperture has a plain bore orifice 116 and is threaded 117 below the plain bore. Thus, when the plug is screwed in, the dry-break member is fluid tight as normal.

A capless filler pipe closure is provided for a tank filler pipe. The capless closure permits a fuel pump nozzle to be inserted into the tank filler pipe without first removing a fuel cap from the outer end of the tank filler pipe.

A tubular fuel filler pipe body is a blow molded body and is adapted to connect to a fuel tank at one end thereof. The fuel filler pipe body includes in an outer circumferential surface of another end side thereof an annular recessed groove. The fuel filler pipe body includes an opening of the other end thereof to which a nozzle guide is mounted. The nozzle guide includes on an one end side thereof an annular covering portion configured to cover annularly the outer circumferential surface of the other end side of the fuel filler pipe body. An annular rubber sealing member configured to seal between an inner circumferential surface of the annular recessed groove and an inner circumferential surface of the annular covering portion fits with the annular recessed groove.

A valve member provides for the flow of vapors from a fuel tank of an internal combustion engine to escape the fuel tank. The valve member may include a valve and a boss or spacer. The valve is configured to selectively control the flow of vapor from the fuel tank. The boss or spacer is positioned in a predetermined relationship to the valve, and the boss or spacer prevents a deformation of the valve from disrupting the selectively controlled flow of vapor from the fuel tank.

A tank closure for motor vehicles, includes a locking part (12) for locking on a complementary locking part of the tank nozzle, a closure part (14) for covering an opening of the tank nozzle, and an axially compressible sealing ring (20) surrounding the locking part (12) and supported on a flange (18) of the closure part (14), wherein the flange (18) has, at least on a part of its circumference, a bead (26) which is integrally formed on its surface (24) facing the sealing ring (20) and which is elevated relative to the surface (24), wherein the inner edge of the bead has a radius that is greater than the radius of the peak (34) of the sealing ring.

A fuel device assembly including a valve assembly and a baffle plate, the valve assembly including a valve cover and a first weld plate provided at an upper end of the valve cover coupling the valve assembly to an interior-facing surface a fuel tank of a vehicle, the baffle plate including a body having a plurality of spaced apart holes formed therein and a housing member extending from the body for receiving and lockingly engaging the valve assembly.

A charging connection device for a vehicle includes a junction box disposed in a recess, a junction box cover flap, and a cover flap. The junction box cover flap and the cover flap are each pivotable into an open position and a closed position. The junction box cover flap covers the junction box in the closed position and the recess is coverable by the cover flap. When the cover flap is displaced from the open position into the closed position the cover flap entrains the junction box cover flap. The junction box cover flap has a first element of a junction box connecting device and the junction box or a component that defines the recess has a second element of the junction box connecting device. In the closed position of the junction box cover flap, the junction box cover flap is held magnetically releasably by the junction box connecting device.

A reservoir cap closure indicator coupled to a cap comprises a body configured to move between a first position and a second position. An indicator coupled to the body indicates a position of the reservoir cap closure indicator as the body moves between the first position and the second position.

Disclosed are a fuel door having a cap sealing structure which obviates a cap for urea solution or water injection and a vehicle including the same. The fuel door includes a protrusion configured to protrude from an inner side of the fuel door and comprising a hollow and at least one cutout part being in fluid communication with the hollow, a membrane member coupled to the protrusion so as to cover the hollow of the protrusion, and a sealing member installed on the protrusion along a circumference of the membrane member.

An in-tank fuel pump assembly and mounting system is disclosed which may be configured for mounting inside a fuel tank. The assembly includes a pump housing, pump mounted to the housing, and pressure relief valve. The housing may comprise upper and lower pump housing units coupled together. The upper housing unit is configured for mounting to a tank opening, which in one implementation may be the fuel fill opening. The lower housing unit extends into the tank to approximately the bottom of the tank. A fuel fill fluid pathway is created through the housing for adding fuel to the tank while the pump assembly remains in situ. The upper housing unit may include a removable fuel cap. The pump housing may include an integral vapor trap.
