An opening-closing device for a fuel supply passage includes a tubular passage forming portion having a fuel inlet port, a flap having an engagement portion, and an opening-closing actuating member. The opening-closing actuating member includes a main body and movable portions coupled to the main body. Each movable portion includes a proximal portion, an arm extending in the circumferential direction from the proximal portion, a nozzle detecting portion protruding inward in the radial direction from the arm, and an engaging portion. When the nozzle detecting portions do not receive a pushing force, the engaging portions are engaged with the engagement portion to lock the flap in a closing state in which the flap closes the fuel inlet port. When the nozzle detecting portions receive the pushing force, the engaging portions are disengaged outward in the radial direction from the engagement portion to unlock the flap.

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.

A closure device for a fluid container, in particular a hydraulic tank, has a base (4), which can be attached to the container opening and has a cover part (2), which encloses a ventilation and/or a filter device (36). The cover part (2) is held on the base (4) so as to be freely rotatable in a functional unlocking position. In a functional locking position, the closure device permits the container opening to be unlocked by a safety device (48, 50, 58) while connecting the cover part (2) to the base (4). The safety device (48, 50, 58) can be actuated by a magnetic device generating a magnetic field (62). The magnetic device establishes the functional locking position of the cover (2) and the base (4) by magnetic force.

A gas differentiating nozzle device includes a tubular housing made of a fuel resistant material having a perpendicularly positioned dowel passing through a near center portion of the device. A first half of the device above the dowel further comprises a plurality of concentric interior tubes in fluid communication with a second half of the device below the dowel which further comprises a plurality of rectangular vents disposed near the second half end of the device.

A filler neck (1) for filling an operating substance, such as fuel or AdBlue® or urea, or an additive, such as water, into a vehicle tank by way of a fuel pump nozzle. The filler neck (1) has a filler neck body (2), which can be accommodated in a filler pipe leading to the vehicle tank. The filler neck (1) furthermore has a fuel pump nozzle guide with an insertion section (4) for guiding a fuel pump nozzle, which is accommodated or is to be accommodated in the filler neck body (2), in the direction of the vehicle tank. The filler neck body (2) and the insertion section (4) of the fuel pump nozzle guide are formed together as an integral casting, in particular plastics injection moulding.

A fuel device FS includes a discriminating portion 50, an operation member, an abutting member 57 and an open/close member 70. The discriminating portion 50 includes an discrimination opening GL formed of a first portion and a second portion. The first portion is an opening corresponding to an external diameter of a small-diameter nozzle FNS. The second portion is an opening having a shape corresponding to an external diameter of a large-diameter nozzle FNL compatible with the fuel device. The operation member 51 of the discriminating portion 50 guides the small-diameter nozzle intended to insert into the second portion to be inserted into the first portion. The abutting member 57 prevents a tip of the small-diameter nozzle from passing the first portion. The open/close member 70 is caused to enter an open state by the large-diameter nozzle passing through the second portion of the discrimination opening GL.

A filler neck (1) for filling an operating substance, such as fuel or AdBlue or urea, or an additive, such as water, into a vehicle tank by way of a fuel pump nozzle. The filler neck (1) has a filler neck body (2), which can be accommodated in a filler pipe leading to the vehicle tank. The filler neck (1) furthermore has a fuel pump nozzle guide with an insertion section (4) for guiding a fuel pump nozzle, which is accommodated or is to be accommodated in the filler neck body (2), in the direction of the vehicle tank. The filler neck body (2) and the insertion section (4) of the fuel pump nozzle guide are formed together as an integral casting, in particular plastics injection moulding.

Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter 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 closure device for a fluid container, in particular a hydraulic tank, having a base (4), which can be attached to the container opening thereof, and a cover part (2), which encloses a ventilation and/or a filter device (36), is held on the base (4) so as to be freely rotatable in a functional unlocking position and, in a further functional locking position, permits the container opening to be unlocked by means of a safety device (48, 50, 58) while connecting the cover part (2) to the base (4), is characterized in that the safety device (48, 50, 58) can be actuated by a device generating a magnetic field (62), which device establishes the further locked functional position of the cover (2) and the base (4) by means of magnetic force.

A flame mitigation device (FMD) for use within a portable fuel container includes a generally cylindrical body having an interior sidewall and exterior sidewall. An annular rim is configured at an upper end of the body and a bottom wall is further configured at a lower end of the body. The FMD includes one or more indented fuel flow members extending from the interior of the annual rim for decreasing cyclonic effect of fuel flowing into the body and a plurality of stepped ribs configured on the interior sidewall of the body for centering diesel and gasoline fuel pump nozzles when inserted into the body. A reverse domed shaped bottom help to disperse fuel though a plurality of substantially rectangular shaped holes through the side wall and bottom wall.
