Definitions

  • the present invention relates generally to a fuel filling system for an automotive vehicle. II. DESCRIPTION OF RELATED ART
  • All automotive vehicles include fuel filling systems to allow the fuel tank of the vehicle to be refilled.
  • the fueling system includes a funnel which is dimensioned to receive a conventional fuel filling nozzle.
  • the funnel in turn is connected to the fuel tank for the vehicle.
  • fuels include diesel fuel and unleaded gasoline.
  • the diameter of the fuel nozzle for each of the different fuels is different.
  • the diameter of the fuel nozzle for diesel fuel has a larger diameter than the fuel nozzle for unleaded gasoline.
  • the use of the wrong fuel in the engine for the automotive vehicle may result in destruction of the engine.
  • the fuel nozzle for unleaded gasoline is smaller in diameter than the fuel nozzle for diesel fuel.
  • flexible latches engage and retain the fuel valve in a closed position. Upon insertion of the properly sized fuel nozzle, the fuel nozzle engages the latches and flexes the latches outwardly to disengage the fuel valve and allow the fuel valve to open.
  • the prior art device incorporates only one door between the interior of the fuel funnel and the environment, which may permit dust or debris to compromise the seal on the fuel valve.
  • Other systems use a one-piece secondary valve which necessitates more space to the primary door.
  • a one-piece valve also creates a side load on the nozzle, which is not ergonomically desirable to the operator.
  • the present invention provides an automotive fuel filling system which overcomes the above-mentioned disadvantages of the previously known devices.
  • the fuel filling system of the present invention comprises a funnel assembly having a generally circular port.
  • the funnel assembly is fluidly connected to the fuel tank for the automotive vehicle and is adapted to receive a fuel filling nozzle.
  • a nozzle valve assembly having at least two segments is disposed in series with said port and preferably immediately downstream from the port. Each of these segments is pivotal between an open and a closed position while a spring or other biasing means urges the segments towards their closed position.
  • a hook is attached to a radially inner end of each valve segment.
  • a cam is associated with each valve segment and these cams are shaped and located such that as a nozzle is inserted, the valve segments are spread apart.
  • the larger nozzle engages the cams, pivoting the valve segments sufficiently to provide clearance between the nozzle and the hooks which allows the fuel nozzle to be moved to a fully inserted position in the funnel assembly. In doing so, the nozzle opens a flapper valve downstream from the nozzle valve assembly thus enabling fueling of the vehicle.
  • the cams do not spread the valve segments sufficiently to create clearance between the nozzle and the hooks and at least one of the hooks on one of the nozzle valve segments engages the end of the nozzle and prevents full insertion of the smaller nozzle into the diesel funnel assembly. This, in turn, prevents refueling of the vehicle with the smaller nozzle since the flapper valve remains in a closed position.
  • FIG. 1 is a fragmentary exploded view illustrating a preferred embodiment of the present invention prior to insertion of the fuel nozzle into the funnel assembly;
  • FIG. 2 is a fragmentary sectional view similar to FIG. 1, but illustrating the fuel nozzle inserted into the funnel assembly;
  • FIG. 3 is an outside plan view of the preferred embodiment of the present invention
  • FIG. 4 is a fragmentary partial sectional view illustrating a preferred embodiment of the present invention.
  • FIG. 5 is a fragmentary sectional view illustrating the operation of the present invention with enhanced hooks and the parts removed for clarity.
  • an embodiment of the fuel filling system 10 of the present invention includes a funnel assembly 12.
  • the funnel assembly 12 has an open outer end adapted to receive a fuel nozzle 16.
  • the other end 18 of the funnel assembly 12 is fluidly connected to a fuel tank 20 (illustrated only diagrammatically) for an automotive vehicle.
  • the funnel assembly 12 further includes a fluid port 22 in series between the ends 14 and 18 of the funnel assembly 12.
  • This port 22 has a diameter slightly greater than the diameter of the fuel nozzle 16 for the proper fuel of the automotive vehicle. Consequently, if the automotive vehicle (not shown) operates on unleaded gasoline, the port 22 is sufficiently small to prevent the insertion of a fuel nozzle for diesel fuel. Conversely, if the vehicle utilizes diesel fuel, the port 22 is large enough to accommodate the larger diameter funnel 16 for diesel fuel and thus is necessarily larger than the diameter of a nozzle funnel 16 for unleaded gasoline.
  • a nozzle valve assembly 24 having a plurality of valve segments 26 is mounted within the funnel assembly 12 so that the nozzle valve assembly
  • the nozzle valve assembly 24 is fluidly positioned in series between the funnel inlet 14 and outlet 18 and preferably at or immediately downstream from the funnel port 22. As illustrated in the drawing, the nozzle valve assembly 24 includes four segments 26 (see FIG. 3), but it will be understood that fewer or more nozzle valve segments may be employed without deviation from either the spirit or scope of the invention.
  • each nozzle valve segment 26 is generally pie shaped and is pivotal between its lowest position, illustrated in FIG. 3, and an open position, illustrated in FIG. 2.
  • a cam 28 is attached to each nozzle valve segment 26 so that the cams 28 face outwardly through the inlet 14 of the funnel assembly 12.
  • the cams 28 are configured such that, upon insertion of the larger diesel nozzle 16, the nozzle 16 pivots the valve segments 26 open and creates a clearance between the hooks 30 and the end of the nozzle 16. Conversely, upon insertion of the smaller nozzle 16', the coaction between the end of the nozzle 16' and the cams 30 does not sufficiently spread the valve segments open to create a clearance between the nozzle end and the hooks 30.
  • each nozzle valve segment 26 also includes a hook 30 at its radially inner end.
  • the ability to resist insertion of undersized nozzles is enhanced if the hooks engage the inner diameter of the nozzle tip as shown in FIG. 5.
  • Rocking the nozzle may sequentially disengage less aggressive hooks.
  • the nozzle valve segment 26, cam 28 and hooks 30 are all of a one-piece construction.
  • any conventional means such as a spring 32, is used to urge the nozzle valve segments 26 to their closed position as illustrated in FIG. 1.
  • a flapper valve 40 is contained within and fluidly in series with the funnel assembly 12 and movable between a closed position, illustrated in FIGS. 1 and 4, and an open position, illustrated in FIG. 2.
  • the flapper valve 40 is mounted downstream from the nozzle valve assembly 24 and in alignment with the nozzle valve assembly 24.
  • a spring 42 (FIG. 4) urges the flapper valve 40 towards its closed position.
  • valve assembly 24 seals the port 22 and protects the flapper valve 40 from dust and debris.
  • the free end of the fuel nozzle 16 engages all of the cams 28 on the nozzle valve segments 26 and thus pivots the nozzle valve segments 26 from their closed position, illustrated in FIG. 1, and to an open position, illustrated in FIG. 2.
  • the fuel nozzle 16 is movable to a fully inserted position, illustrated in FIG. 2, in which the free end of the fuel nozzle 16 engages and moves the flapper valve 40 from its closed and to its open position. At that time, normal fueling of the automotive vehicle may proceed.
  • the free end of the fuel nozzle 16' engages all of the cams 28 on the nozzle valve segments 26, but not sufficiently to create clearance between the tip of the nozzle and the hooks. Consequently, upon an attempt to further insert the fuel nozzle 16' into the funnel assembly 12, the hooks 30 on the nozzle valve segments 26 which were not sufficiently opened by the nozzle 16' engage the free end of the fuel nozzle 16' and prohibit the further insertion of the fuel nozzle 16' into the funnel assembly 12. At this time, the flapper valve 40 remains in a closed position thus preventing fueling of the automotive vehicle with the improper fuel.

Abstract

L'invention concerne un système de remplissage en carburant pour automobiles qui empêche l'alimentation d'une automobile en carburant à partir du plus petit de deux becs diffuseurs de carburant de diamètres différents. Le système comprend un ensemble entonnoir comportant un port circulaire conçu pour recevoir le bec diffuseur de carburant. Un ensemble soupape de bec diffuseur comprend deux segments au moins et est disposé en série avec le port. Chaque segment peut de plus pivoter entre une position ouverte et une position fermée. Lorsque tous les segments sont en position fermée, l'ensemble soupape de bec diffuseur sert à empêcher la poussière et les débris d'atteindre la soupape à clapet. Un crochet de retenue est fixé à l'extrémité intérieure radiale de chaque segment de soupape de bec diffuseur, et une came est également fixée à chaque segment de soupape de bec diffuseur, afin de créer un jeu entre l'extrémité du bec diffuseur le plus grand (uniquement) et les crochets lors de l'insertion du plus grand des becs diffuseurs, et non lors de l'insertion du plus petit des becs diffuseurs.
