20090084464Filler neck - The filler neck includes a neck tube body having a fuel passage a guide member for guiding the fuel gun and a recirculation passage that connects the fuel tank and the neck tube body through a passage separate from the fuel passage, and that directs fuel vapors inside the fuel tank into the fuel passage. The neck tube body includes a housing chamber a primary connector section and a secondary connector section connected to the housing chamber and defining part of the recirculation passage. The guide member is a member that is housed in the housing chamber and includes a guide section for guiding the fuel gun into the fuel passage and a passage-defining section formed in the guide section, and partly defining the recirculation passage inside the housing chamber.04-02-2009
20090188582TANK OPENING-CLOSING DEVICE - The tank opening-closing device is realized with a simple constitution of the opening-closing mechanism equipped with a pressure adjustment valve for regulating the internal pressure of the fuel tank. The opening-closing mechanism is equipped with a gasket provided on the opening peripheral edge part of the inlet of the tank opening forming member, the valve opening-closing mechanism for opening and closing the inlet and also regulating the internal pressure of the fuel tank, and a retraction mechanism that selectively moves the valve opening-closing mechanism to the closing position and the fueling position in conjunction with the fueling gun, The valve opening-closing mechanism has a closing position for opening and closing the inlet and a fueling position retracted from the inlet for which it is possible to supply fuel.07-30-2009
20090189106Tank opening-closing device - The tank opening-closing device is equipped with a tank opening forming member having a fuel path for leading fuel supplied from the fueling gun through the inlet to the fuel tank, a valve opening-closing mechanism having an opening-closing member and spring that closes in a state with the inlet sealed, and an opening-closing activation mechanism for opening and operating the opening-closing member. The opening-closing activation mechanism has an operating member pivoted at the tank opening forming member, and a pressing member for pressing the opening-closing member formed on the operating member, and is constituted so that by the operating member being pressed by the fueling gun and rotating, the opening-closing member is pressed by the pressing member and is rotated in the opening direction so as to open the inlet.07-30-2009
20100133274Fuel tank opening-closing device - A fuel tank opening-closing device includes a shutter mechanism situated inside a tank neck defining member and adapted to open a shutter body in response to insertion of a fuel nozzle. The shutter mechanism includes a push mechanism having a push member situated in an insertion passage; an interconnection mechanism having springs adapted to accumulate force of displacement of the push member as mechanical energy; and a nozzle sensing mechanism. The nozzle sensing mechanism has introduction pressure members adapted to receive displacement force of the fuel nozzle in the insertion direction, and lock portions that allow the shutter to move to the opening position.06-03-2010
20100218849Fuel tank opening-closing device - A fuel tank opening-closing device includes a flap valve mechanism situated inside a tank opening forming member and having a flap valve mechanism; and an opening-closing activation mechanism adapted to selectively set the flap valve mechanism to a locked position or an unlocked position. The opening-closing activation mechanism includes a cover covering the peripheral edge portion of the opening-closing member and having a cover body produced by being split into arcuate shapes of prescribed width; a nozzle detection mechanism having introductory push parts that are adapted to receive force of motion in the insertion direction by a fueling nozzle; locking members which engage or disengage from the opening-closing member; and a locking mechanism having and adapted to move the locking members from the locked position to the unlocked position through interlocking operation with the introductory push parts.09-02-2010
20110104379MANUFACTURING METHOD FOR ELASTIC MEMBER - The present invention provides a sealing member for fuel which includes a fluororubber base and a sliding-treated layer coating the surface of the base. The sliding-treated layer includes a matrix made from a fluororubber, a sliding thin film formed in the surface portion of the matrix from a molten first particulate solid lubricant, and a second particulate solid lubricant dispersed in the matrix and the sliding thin film without being melted.05-05-2011

20110240640FUEL TANK OPENING AND CLOSING DEVICE - A fuel tank opening and closing device is equipped with a flap valve mechanism having an opening and closing member for opening and closing an inlet inside a tank opening forming member. The nozzle positioning guide mechanism has a first support mechanism of an opening peripheral edge of an introduction port of an insertion path of a tank opening forming member, a second support mechanism having an introduction guide surface formed on the top surface of the pressing member of the opening and closing member, and a positioning ridge line that has a curvature almost the same but slightly larger than the outer diameter of the fueling nozzle and which touches by line contact on the outer peripheral surface of the fueling nozzle at the insertion completion position, and a third support mechanism having a valve positioning member which regulates the degree of openness of the opening and closing member by touching the inner wall of the tank opening forming member.10-06-2011
20120000134FUEL TANK OPENING AND CLOSING DEVICE - A fuel tank opening and closing device is equipped with a flap valve mechanism arranged inside the tank opening forming member, having an opening and closing member for which the inlet is opened and closed by being pressed by the tip of the fueling nozzle, a shaft provided at the tip of the opening and closing member, and a bearing mechanism provided on the tank opening forming member for supporting the shaft so as to be rotatable. The bearing mechanism has a shaft support recess in which the shaft is inserted and a plurality of shaft restriction projections provided projecting from the wall surface of the shaft support recess, and the shaft restricting projections have a cross section arc shaped shaft support surface such that there is contact with a portion of the outer periphery of the shaft.01-05-2012
