| 20090084464 | Filler 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 |
| 20090188582 | TANK 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 |
| 20090189106 | Tank 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 |
| 20100133274 | Fuel 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 |
| 20100218849 | Fuel 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 |
| 20110104379 | MANUFACTURING 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 |
