摘要： An improved below-ground apparatus and method for fueling a vehicle through an inlet on a exposed tank bottom. The apparatus is characterized by a frame carrying an upwardly-facing nozzle, a lift to move the frame and the nozzle from a fully-retracted to an intermediate position and from the intermediate position to a position for full engagement with the inlet. The intermediate position is determined by sensing the vertical position of the tank bottom and, at the intermediate position, the nozzle member is positioned on the frame in vertical alignment with the inlet prior to final lifting. In preferred embodiments, a blower creates an air ride for the nozzle member facilitating its positioning on the frame, and another blower creates a vacuum to hold the nozzle member is proper position and to eliminate fuel vapors. The nozzle member is preferably conical in shape.

摘要： A fuel-intake device for automatic bottom fueling. The device includes spaced inner and outer barrier walls with edge portions joined together, first and second aligned openings in the barrier walls, and a standpipe having a proximal end secured to the inner wall about the second opening and a distal end having a fuel outlet spaced from the inner wall. Two annular seals preferably allow a conical nozzle to sealingly engage both barrier walls. Other preferred embodiments relate to barrier wall, seal, and standpipe configurations, fuel and vapor pressure relief valves, entry doors and a protective cover.

摘要： An improved nozzle apparatus and method for automatic engagement with a bottom inlet. The apparatus is characterized by a frame and an upwardly-facing nozzle member carried by the frame and horizontally movable thereon into a position of vertical alignment with the inlet. In preferred embodiments, a blower creates an air ride for the nozzle member facilitating its positioning on the frame, and another blower creates a vacuum to hold the nozzle member in proper position for engagement with the inlet. The nozzle member is preferably conical in shape.
