Description

RESERVOIR ASSEMBLY HAVING INTERCHANGEABLE FUEL SUCTION UNIT AND FUEL PUMP ASSEMBLY FOR VEHICLES
This application is based on U.S. Provisional Application No.60/487,086, filed on July 14, 2003 and U.S. Provisional Application No. 60/507,558 filed on October 1 , 2003 and claims the benefit each provisional application for priority purposes.
FIELD OF THE INVENTION
The invention relates to fuel supply module for automobile vehicles and more particularly, to a reservoir assembly capable of housing a fuel suction unit or a fuel pump assembly for use in a fuel tank of a vehicle.
BACKGROUND OF THE INVENTION
In diesel-fueled vehicles, there is either a fuel suction module or a fuel supply module provided in the fuel tank. The fuel supply module contains an electric driven fuel pump and filter and is configured to supply fuel from a reservoir in the tank to the engine. When the fuel suction module is provided instead of the fuel supply module, the fuel suction module ensures that sufficient fuel is provided in the reservoir such that when the fuel tank is low on fuel, the engine will draw fuel from the reservoir instead of drawing in air. Conventionally, the two modules are completely separate configurations which increases design time and cost.
Thus, there is a need to provide a single assembly with an interchangeable fuel suction unit and fuel pump assembly.
SUMMARY OF THE INVENTION
An object of the invention is to fulfill the need referred to above. In accordance with the principles of the present invention, this objective is achieved by providing a reservoir assembly for a fuel tank of a vehicle. The reservoir assembly is constructed and arranged to receive either an electric fuel pump assembly or a fuel suction unit in a reservoir thereof. The fuel suction unit and the electric fuel pump assembly are configured so as to be interchangeably received in the reservoir.
In accordance with another aspect of the invention, a reservoir assembly for a fuel tank of a vehicle includes a reservoir constructed and arranged to contain fuel. A fuel suction unit is disposed in the reservoir. The fuel suction unit has a filter structure constructed and arranged to filter fuel that passes through at least a portion thereof, and suction tube assembly having a suction tube extending within an interior of the filter structure for drawing filtered fuel from within the interior of the filter structure. The suction tube is constructed and arranged to be in communication an engine of the vehicle.
Other objects, features and characteristics of the present invention, as well as the methods of operation and the functions of the related elements of the structure, the combination of parts and economics of manufacture will become more apparent upon consideration of the following detailed description and appended claims with reference to the accompanying drawings, all of which form a part of this specification.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENT
With reference to FIG. 1 , a reservoir assembly, generally indicated at 10, is shown in exploded view in accordance with the principles of the present invention. The reservoir assembly 10 includes a reservoir 12 for containing fuel such as diesel fuel. A conventional jet pump assembly, generally indicated at 14, is provided in the reservoir 12 and is in communication with an engine (not shown) via tube 16 coupled with a nipple 17. The jet pump assembly 14 includes the conventional spring-loaded check valve assembly 19 and jet pump nozzle (not shown). The jet pump assembly 14 is constructed and arranged to draw fuel from a source of fuel, such as a fuel tank, past valve 15 and into reservoir 12 through an opening in the bottom thereof in the conventional manner.
With reference to FIGs. 1 and 6, the reservoir assembly 10 includes a fuel suction unit, generally indicated at 23, including a generally cylindrical, hollow filter structure 18 that is preferably completely molded from a plastic material suitable for contacting diesel fuel. The filter structure 18 preferably has a plurality of mesh openings 21 of about 1500 micrometers extending through the periphery for filtering the diesel fuel as the fuel in the reservoir 12 passes through at least a portion of the periphery of the filter structure 18 into interior 25. The filter structure 18 includes a main filter 20 and a suction tube-receiving portion 22 extending there-from and in fluid communication therewith. The main filter 20 provides the main fuel-filtering function. The suction tube-receiving portion 22 is optional and has a diameter less then the main filter 20 and also provides filtering in a deeper portion of the reservoir 12.
The suction unit 23 also includes a suction tube assembly 24 that includes a suction tube 26, provided in the interior 25 of the filter structure 18, and has an open end 27 extending into the suction tube-receiving portion 22. The suction unit 23 also includes a cover 30 integral with the suction tube 26. An end 28 of the suction tube 26 is in communication with a diesel engine via tubes 27 and 29 (FIG. 2) to supply filtered fuel from reservoir assembly 10 to the engine (not shown). The cover 30 closes the open end 32 of the filter structure 18 in preferably a snap fit arrangement. In particular, the end 32 of the filter structure 18 includes an annular recess that receives an annular ridge of the cover 30. The suction tube assembly 24, when coupled with the filter structure 18, defines the suction unit 23.
The filter structure 18 also includes and annular flange 35 at a position between the main filter 20 and the suction tube receiving portion 22. The flange 35 is constructed and arranged to support the filter structure 18 on an interior surface 37 of a frame member 39 of the suction jet pump assembly 14 (FIG. 4). A retainer 38 is associated with the suction unit 23 and functions as a support and retainer. The reservoir assembly 10 with suction unit 23 therein is shown in an assembled condition in FIG. 5. The suction unit 23 is part of a fuel suction module, generally indicated at 42 in FIG. 2. The fuel suction module 42 is shown mounted in a fuel tank 40 in FIG. 3.
The function of the suction unit 23 in cooperation with the jet pump 14 is to ensure that fuel is provided in the reservoir 12 to supply fuel to the engine even if the fuel tank 40 contains little fuel. For example, if the fuel tank 40 of FIG. 3 contains little fuel and the vehicle is negotiating a curve, the engine will draw fuel from the reservoir 12 and through the suction unit 23 instead of drawing in air. The suction unit 23 also functions to filter fuel and can also indicated fuel level.
In diesel-fueled vehicles, there is either a fuel suction module 42 or a fuel supply module provided it the fuel tank. The difference is that the fuel supply module contains an electric driven fuel pump assembly, generally indicated at 44 in FIG. 7. The fuel pump assembly 44 includes a pump 45 and a filter 47. FIG. 8 shows the fuel pump assembly 44 mounted in a reservoir assembly 10. An advantageous feature of the invention is that the suction unit 23 is configured (e.g., sized and shaped) so that a user can replace it with a fuel pump assembly 44 without changing any other parts of the reservoir assembly 10. Thus, the filter structure 18 of the suction unit 23 has a generally cylindrical configuration of a size substantially similar to the generally cylindrical pump assembly 44. Accordingly, one basic configuration is provided so that it is easy to change from a fuel suction module to a fuel supply module, or vise-versa.
FIG. 9 shows the interchangeability of the fuel pump assembly 44 and suction unit 23 in a reservoir 12. This interchangeability advantageously saves design time and, from a supplier's point of view, provides more flexibility.
Although the embodiment is described with reference to diesel fuel, other fuels such as bio-diesel or a mixture of gasoline and diesel can be used. The foregoing preferred embodiments have been shown and described for the purposes of illustrating the structural and functional principles of the present invention, as well as illustrating the methods of employing the preferred embodiments and are subject to change without departing from such principles. Therefore, this invention includes all modifications encompassed within the spirit of the following claims.
