A filling device for an operating fluid tank, comprising a tubular outer part and an inner part which is received in the outer part and which is designed to receive an operating fluid nozzle, is characterized in that the inner part comprises a first end wall having an opening and a second end wall having an opening, the end walls being connected to one another via a shell and the shell being provided over the entire length between the end walls with a shell opening whose width corresponds substantially to the corresponding maximum inner width of the shell.

A filler tube, which is capable of satisfying required functions suitably in compliance with the bellows and non-bellows cylindrical base while securing weld strength and fuel-permeation resistance property in the weld face, is provided. A filler tube includes a non-bellows cylindrical base with a total thickness of from 2 to 4 mm, a bellows with a total thickness of from 0.5 to 3 mm, and a flange having a total thickness of from 3.5 to 5 mm, and including an end face to be welded to a fuel tank. The non-bellows cylindrical base, the bellows, and the flange include inner layers formed so as to have a thickness accounting for from 40 to 60% of the total thicknesses, and formed of high-density polyethylene (or HDPE) serving as the major constituent, intermediate layers exhibiting fuel-permeation resistance property, and outer layers protecting the intermediate layers.

A filler pipe is attached to a retainer that holds a fuel nozzle holder. The retainer includes: a first attaching portion attached to an inlet portion of the filler pipe; a holding portion having an engaging hole; and an opening positioned at a first end of the retainer, which is closer to a longitudinal center of the filler pipe than a second end is. The fuel nozzle holder includes: a second attaching portion and including an engaging piece that engages the engaging hole; and a main body extending from the second attaching portion toward the longitudinal center of the filler pipe. The engaging piece is surrounded at three sides by a groove having a U-shape. The engaging piece is connected to the second attaching portion on the main body-side. The holding portion extends toward the longitudinal center of the filler pipe to cover the groove.

A retainer that holds a fuel nozzle holder is mounted to a filler pipe. The retainer includes: a first attaching portion mounted at the filler pipe; an opening located at a first end of the retainer, which is closer to a center of the filler pipe than a second end; and a holding portion having engaging holes. The fuel nozzle holder includes: a second attaching portion having a cylindrical shape and including two engaging pieces engaged in the engaging holes and located on opposite sides in a circumference of the second attaching portion. The engaging pieces are each surrounded by a groove at three sides and joined to the second attaching portion on one, and the two engaging pieces are different from each other in terms of a maximum value of a length in a circumferential direction of the second attaching portion.

A method of producing a deflector device for a fuel tank system comprising producing a deflector device prototype from prefabricated components of a construction kit, performing fuel-refilling tests using the deflector device prototype, optionally modifying the deflector device prototype, creating a construction model for the deflector device prototype, producing a deflector device according to the construction model, optionally performing fuel-refilling tests with the deflector device produced according to the construction model and optionally producing the deflector device according to the construction model. The disclosure further provides a construction kit with prefabricated components for producing the prototype of the deflector device for the fuel tank system.

A fueling device comprises a passage-forming member, an opening-forming member configured to form an opening, a filler port open-close mechanism that includes an open-close member configured to open and close the opening, a screwing mechanism that includes an outer circumferential threaded section and an inner circumferential threaded section and a gasket placed between the opening-forming member and the passage-forming member to seal between the opening-forming member and the passage-forming member, wherein the outer circumferential threaded section is provided on outer periphery of the passage-forming member, the inner circumferential threaded section is provided on the opening-forming member and screwed to the outer circumferential threaded section, the opening-forming member is attached to the passage-forming member by screwing the outer circumferential threaded section to the inner circumferential threaded section.

Some embodiments are directed to a cover assembly for a fuel filler pipe that is disposed adjacent vehicle suspension components. The cover assembly can include a first cover portion that includes a first extension that extends in a first direction and a second extension that extends in a second direction that intersects the first extension at an angle, the first cover portion forming a channel defined by a first cover portion wall that is configured to wrap around a portion of an outer perimeter of the fuel filler pipe so as to leave a section of the outer perimeter of the fuel filler pipe exposed so as to permit movement of the exposed outer perimeter section, the first cover portion being configured to extend more than half a length of the fuel filler pipe.

A fuel tank fill assembly includes a fuel fill tube adapted to be coupled to a fuel tank and configured to receive fuel discharged by a pump nozzle. The assembly also includes a tube mounting bracket for mounting the fuel fill tube in a stationary position in a vehicle to conduct fuel to the fuel tank.

A filler neck assembly including a main channel for supplying a liquid into a tank and an auxiliary channel for evacuating gas from the tank. The main channel includes a tubular main body including a first end receiving a filler spout and a second end discharging the liquid into the tank. The auxiliary channel includes a first section and a second section, the first section being a channel integrally molded with the tubular main body, and the second section being formed by a feature on an exterior of the main body cooperating with a separately formed part.

A fully-integrated flow-control module is designed to fit within a filler neck of a DEF tank that conforms to ISO (International Organization for Standardization) Standard 22241-4:2009(E). The flow-control module includes a breather cap that locks the flow-control module within the mouth of the ISO filler neck. A spring-biased valve piston, which is controlled by a bleed path within a bleed and float body, opens and closes to control fluid flow into the DEF tank. A fluid level float is mounted on a control rod. The control rod and a bleed valve poppet are rigidly secured to a connector beam. When fluid levels in the tank raise the float, the bleed valve poppet seals a bleed circuit escape port, thereby enabling the valve piston to close, increase fluid pressure at the nozzle, and cause the nozzle to shut off.
