20110240640 | FUEL 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 |
20120000134 | FUEL 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 |

20130075395 | FUEL TANK OPENING-CLOSING DEVICE - The fuel tank opening-closing device has a tank opening forming member, a first flap valve mechanism and a second flap valve mechanism with a gasket GS. The tank opening-closing member includes: an insertion passage forming member including a passage forming main body for forming an insertion passage that connects the first opening and the second opening and for guiding the fueling nozzle from the first opening to the second opening, and a vent hole formed at an outer periphery of the first opening of the passage forming main body, a vent forming member having a gap with the insertion passage forming member at an outer periphery of the insertion passage forming member and disposed facing the vent hole, and a vent passage that connects the insertion passage with the outside through the gap and the vent hole. | 03-28-2013 |
20130075399 | FUEL TANK OPENING-CLOSING DEVICE - The fuel tank opening-closing member has a tank opening forming member having a first opening forming member which has a first opening, and a first flap valve mechanism having a first opening-closing member for opening and closing the first opening, and a first shaft for rotatably supporting one end part of the first opening-closing member. The first opening-closing member is equipped with a pressing part having a push face pressed by the tip of the fueling nozzle, and a restriction wall forming a restriction region which restricts so as to allow insertion only of specified fueling nozzle external shapes established along the outer edge of the push face, enclosing at least a portion of the push face, and a guide member which is formed tilted toward the top part of the restriction wall, and leads the tip of the fueling nozzle to the restriction region. | 03-28-2013 |
20130193140 | FUEL TANK OPENING-CLOSING DEVICE - A fuel tank opening-closing device has a tank opening forming member, a flap valve mechanism that has an opening-closing member, and an opening-closing activation mechanism that switches between the locked position and the unlocked position that does the opening operation of the opening-closing member. The opening-closing activation mechanism has a nozzle detection mechanism which has introductory push parts mounted on the opening-closing member and adapted to receive force of motion in the insertion direction of the fueling nozzle, and a lock member that is mounted on the tank opening forming member and that selectively shifts between the locked position and the unlocked position by engaging and disengaging with the opening-closing member, and a locking mechanism that moves the locking member from the locked position to the unlocked position by being pushed by the introductory push parts. | 08-01-2013 |
20140091095 | FUEL TANK OPENING AND CLOSING DEVICE - A fuel tank opening and closing device is equipped with a tank opening forming member equipped with an injection port forming member having an insertion path and a tank side path arranged outside and inside an injection port, an injection port opening and closing mechanism for opening and closing the injection port, an insertion path forming member, and a drainage mechanism having a drainage path that connects the insertion path and the outside, and exhausts to the outside fuel that has accumulated inside the insertion path, and barrier members arranged on the drainage path. The barrier members are arranged with a labyrinth as the drainage path so that the insertion path cannot be seen from outside. | 04-03-2014 |
20150048087 | FUEL TANK OPENING AND CLOSING DEVICE - A flap valve mechanism in an open-close device for fuel tank includes an open-close member, a shaft support mechanism, a spring and a gasket. The shaft support mechanism includes bearing members and a rotation restricting mechanism. The rotation restricting mechanism includes restricting elements and restricted elements to be engaged with the restricting elements. At a first position, the restricting elements are engaged with the restricted elements, so that the open-close member is moved in a direction of warping the gasket. At a second position, the restricting elements are disengaged from the restricted elements, so that the open-close member is rotated about shaft members. | 02-19-2015 |
