ABSTRACT:
A system is disclosed for operating an automated refueling system, the system including: a source of vacuum; a suction cup, the suction cup being capable of mating with a hinged vehicle fuel cap cover and the suction cup having an inside which is in communication with the source of vacuum through a suction system; an extension mechanism effective to laterally extend the suction cup toward a vehicle's hinged fuel cap cover; a vacuum actuated means to swing open the hinged fuel cap cover when a pressure within the suction system approaches the pressure of the source of vacuum; and a vacuum actuated cylinder to extend a filler tube into fuel tank inlet after the hinged fuel cap door is swung open. The system of the present invention minimizes the number of electrical components that are in the vicinity of the refueling nozzle.
