A fuel tank apparatus for a motor vehicle that includes a fuel tank and a filling module configured for connection to the fuel tank. The filling module includes a fuel accumulator and a filler neck configured for fluidic connection to the fuel accumulator in such a way that permits filling to occur place via the filler neck exclusively into the fuel accumulator.

A non-pressure valve is provided, and includes a tubular housing having an inlet and an outlet. The tubular housing forms a fluid flow path. The non-pressure valve also includes a sliding sleeve coupled with the outlet, a spring disposed between the sliding sleeve and the tubular housing, and a flow-through mount disposed within the tubular housing adjacent the sliding sleeve. The flow-through mount is coupled with a bulb. The bulb is configured to engage the sliding sleeve and impede the flow of fuel. The non-pressure valve also includes a hose fluidly coupling the non-pressure valve with a remote fuel vent. The flow-through mount may include a plurality of bypass openings positioned in the fluid flow path and configured to divert a portion of the fuel flow through a hose to the remote fuel vent.

There is provided a check valve for a fuel tank, including a cover to be welded to the fuel tank, a case welded to the cover and having a discharge port configured to discharge fuel into the fuel tank, and a valve body configured to open and close the discharge port. The cover includes a positioning portion on an outer circumferential surface. The case includes a vent hole which is arranged upward in a circumferential direction of the case when the check valve is mounted on the fuel tank, and a valve body supporting portion which supports the valve body inside the case. The valve body supporting portion includes a selecting portion for positioning the vent hole, which is provided on a discharge port side at a position away from the positioning portion by a predetermined angle in the circumferential direction of the case.

Systems are provided for refueling a fuel tank of a motor vehicle via an insert for a filler pipe. In one example, a system may include an insert coupled to an inner circumference of the filler pipe, the insert including a plurality of projections positioned on an inner circumference of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

A fuel supply device (FS) includes a filler neck (10) that includes a nozzle guiding path that guides a fuel supply nozzle (FN), and a fuel passage that is continuous to the nozzle guiding path on a downstream side of the fuel passage, through which fuel that has been discharged from the fuel supply nozzle (FN) passes; a fuel vapor port (23) located outside of the filler neck (10) that has a through hole (23H) that communicates with the fuel passage (11Pd); and a vapor introduction body (70) that guides the fuel vapor from the fuel vapor port to the fuel passage (11Pd). The vapor introduction body (70) includes a within-through-hole support (71) that is inserted into and held in the through hole (23H), and includes a vapor passage (71a) along the through hole (23H), and a changing member (72) that faces an opening of the vapor passage (71a) on a side of the fuel passage (11Pd), and is configured to change a direction of flow of the fuel vapor that passes through the vapor passage (71a) to the side of the fuel passage (71a). The vicinity of the fuel vapor port in the filler neck is configured compactly.

There is provided a fuel supply device comprising a filler neck body provided in a tubular shape to include an opening which a fueling gun is inserted in and a connection port formed on a fuel tank-side end of the filler neck body and configured to form a fuel passage; and a neck integrated component located on an inner side of the filler neck body and configured to form an insertion passage. The neck integrated component is arranged to engage with inside of the filler neck body on a fuel tank side or with a fuel tank-side end of the filler neck body. This configuration suppresses a fueling gun from being stuck during insertion and reduces the possibility that the engagement part of the filler neck body and the neck integrated component is damaged.

An inlet check valve intended to be entirely located within an internal volume delimited by a liquid tank of a vehicle and a filler pipe welded to the tank, the filler pipe defining a downstream direction followed by a liquid filling the tank, and an upstream direction opposite thereto the inlet check valve comprising a tube and, at the upstream end of the tube, resilient means for adapting the form of the tube to the internal wall of the filler pipe. The inlet check valve comprises hook means for securing the tube to an internal wall of the filler pipe and prevent the inlet check valve from moving within the filler pipe. The tube bears a skirt ending with an edge which can merge with the filler pipe wall when the latter is welded to the tank, making the edge a seal part of the inlet check valve.

Methods and systems are provided for a filler inlet of a fuel fill line of a motorized vehicle. In one example, a filler inlet includes a fuel/air separation chamber extending at an angle relative to an opening of the filler inlet, with the opening adapted to receive a fuel nozzle. Fuel may be guided from the fuel nozzle toward a curved wall of the fuel/air separation chamber by a flow guide, and the fuel may separate from entrained air within the fuel/air separation chamber.

A dual cap assembly having multiple passages, may include a pipe device having a plurality of separate passages; a first cap device detachably mounted at a position where the passages diverge in the pipe device to close a first passage; and a second cap device detachably mounted on the first cap device to close a second passage, wherein when the first cap device is separated from the pipe device, the first passage is opened, and when the second cap device is separated with the first cap device mounted on the pipe device, the second passage is opened while the first passage is closed.

A tank connection apparatus connects a tank filler pipe with a fuel tank in a fuel filling line of a vehicle, and it includes: a coupling body containing the mechanism components on its own body and providing connection between a corrugated connection pipe and the tank connector female housing, a corrugated connection pipe mounted between the tank filler pipe and the coupling body, and preventing cracking and/or breaking by extending in situations like accidents, a tank connector female housing mounted to the fuel tank inlet, a locking spring found on the coupling body and fixing the coupling body in the tank connector female housing when the coupling body is attached to the tank connector female housing. The tank connection apparatus also has a safety lock attached to the coupling body and fixing the locking spring with regard to the axis of rotation, and thus preventing it from coming loose.
