Fuel supplying apparatus

A fuel supplying apparatus comprising:

• a fuel supplying nozzle having an ejection pipe for ejecting fuel and a passage for supplying fuel to said ejection pipe;
• an opening and closing valve means provided in said supply passage;
• a nozzle lever for opening said opening and closing valve;
• locking means for locking said opening and closing valve in an open state;
• negative pressure generating means for generating negative pressure upon supply of said fuel outside through said ejection pipe;
• lock releasing means for releasing the lock of said locking means by the introduction of said negative pressure generated by said negative pressure generating means;
• atmosphere introduction means for introducing atmosphere into said lock releasing means to neutralize said negative pressure;
• solenoid valve means for interrupting or allowing the introduction of the atmosphere by said atmosphere introducing means;
• and
• detection means for enabling the detection of the insertion of said ejection pipe inside a fuel intake opening of a vehicle and allowing the atmosphere introduction by said solenoid valve means, and for interrupting the atmosphere introduction by said solenoid valve means when said ejection pipe is not inserted inside said fuel intake opening,
• said opening and closing valve means, locking means, negative pressure generating means, locking releasing means, atmosphere introducing means and solenoid valve means accommodated within said fuel supplying nozzle,
• said detection means consisting of a magnet provided freely displaceable at said ejection pipe, and a reed switch opening or closing according to the displacement of said magnet,
• said magnet undergoing displacement upon insertion of said ejection pipe inside said fuel intake opening to open or close said reed switch by the magnetic force emitted by said displaced magnet so that said solenoid valve interrupts the atmosphere introduction, and
• said lock releasing means releasing the lock of said locking means by use of said negative pressure upon interruption of said atmosphere introduction to close said opening and closing valve.
