Embodiment Construction

[0015] In the following, a preferred embodiment of open-close means for a fill opening of a fuel tank of a vehicle of the invention will be described with reference to the accompanying drawings.

[0016] In FIG. 1, there is shown open-close means 2 that is fitted to a fill opening 11 of a fuel tank 1 of an automobile to be automatically opened and closed. The open-close means 2 has an open-close portion 2A including a threaded cylinder 21 threadedly engageable with the fill opening 11 and a flange 22 that is brought into abutment with a periphery of the fill opening 11 when the threaded cylinder 21 is screwed in the fill opening. The threaded cylinder 21 has in its interior a valve member 23 and a pressing spring 24 to press the valve member 23 against an inner surface of the flange 22 to always keep an opening portion of the fill opening 11 closed.

[0017] The flange 22 has an insertion hole 22a formed in a center portion thereof into which a fuel nozzle (mentioned later) is inserted. I...

Abstract

The invention relates to open-close means for a fill opening of a fuel tank of a vehicle that enables the fill opening of the fuel tank to be easily detected by a fuel filling robot. The open-close means comprises an open-close portion for opening and closing the fill opening and a position identifying member. Also, the invention relates to a fuel filling method using the open-close means, wherein the fuel filling robot is provided with a fuel nozzle and moving means for moving the fuel nozzle so that the fuel nozzle can be operated to move into position of the fill opening under control of signals from the position identifying member of the open-close means.

Description

[0001] 1. Field of the Invention[0002] The invention relates to open-close means for a fill opening of a fuel tank of a vehicle such as an automobile, and to a fuel filling method using the open-close means.[0003] 2. Description of Background Art[0004] Recently, a self-service fuel filling system for enabling a user to fill fuel in the fuel tank of the vehicle by himself / herself has been introduced to dispense with a filling-station attendant and cut fueling costs. The existing self-service fuel filling system, however, involves the drawback that a user must handle or operate the fuel nozzle by himself / herself, so that there is the possibility that a fuel spill may be caused.[0005] It is the object of the invention to facilitate introduction of a fuel filling robot (or a fuel dispensing robot) having the capability of automatically bringing its fuel nozzle into position of a fuel opening of a fuel tank to fill the fuel into the fuel tank, without any need for the user to manually op...
