摘要： A capless fuel unit having an elongated tubular and cylindrical housing open at each end, the housing defining a first and a second longitudinally spaced fluid ports. A first flapper valve is associated with the first fluid port and a second flapper valve with the second fluid port, the flapper valves being movable between open and closed positions and resiliently urged toward their respective closed positions. A pressure relief valve is at least partially contained within an interior of the flapper valves. An arrangement of elastomeric seals incorporating a Graphene-derivative are positioned within the housing in proximity with the flapper valves for resisting hydrocarbon emission from fuel vapors escaping from the unit to the atmosphere.

摘要： An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

摘要： A fuel filler structure includes a cylindrical part having a fueling port and a connecting port; a first flap mechanism and a second flap mechanism that are disposed close to the fueling port and the connecting port of the cylindrical part, respectively, and when a nozzle is inserted through the fueling port, the respective flap mechanisms are pressed by the nozzle to open the fueling port and an opening on the connecting port side; a drain hole formed in the cylindrical part and allowing the inside of the cylindrical part to be communicated with the outside; and an opening and closing valve for opening and closing the drain hole. The opening and closing valve includes a valve mechanism that maintains a closed state of the drain hole through negative pressure suction by a volatile fuel suction mechanism attached to the nozzle.

摘要： A flap valve apparatus includes a main body; a valve body; and a spring member. The main body includes support shafts, and the valve body includes bearing portions. When viewed from the axial direction of the support shaft, the bearing portions has a bearing hole with an inner diameter larger than the outer diameter of the support shaft; and an introduction groove being in communication with the bearing hole from the seal surface side of the valve body. A width of the introduction groove is smaller than the outer diameter of the support shaft, but is expandable to receive the support shaft. When viewed from the axial direction of the support shaft, an opening portion of the introduction grove is positioned near the axial center of the main body.

摘要： A fill tube for an oil tank may have at least one baffle coupled to an inner wall of the fill tube. A first baffle may have an aperture. A release tube may be coupled to the baffle at the aperture. An object may be inserted through the aperture. The object may force open a flapper valve coupled to the fill tube. Pressure in the oil tank may be released through the flapper valve. The baffles may prevent hot oil from spraying out of the fill tube. After the pressure has been equalized, oil may be poured into the fill tube to fill the oil tank.
