Description

FIELD OF THE INVENTION

The present invention relates to a pumping assembly for a fuel delivery vehicle. More specifically, the invention relates to such an assembly with a particular manifold and sequence of valves that permit the user to generate many different flow configurations that may be required for the fuel delivery vehicle.

BACKGROUND OF THE INVENTION

While fuel is often obtained at filling stations, there is often a need for mobile delivery. Various types of mobile fuel dispensers, such as standard tanker trucks, have been employed for carrying and dispensing fuel at needed locations.

The transport and dispensing of fuel in such situations can sometimes present challenges, as is often the case, for example, when delivering fuel to mobile military units and expeditionary bases. In such scenarios, it is often necessary to fill the fuel tanks of remotely located vehicles or provide fuel at temporary installations in order to run generators, heaters, and the like, or to provide for the temporary storage of fuel in containers at that remote site. Such fueling destinations, which may be in need of regular replenishment and may have varied locations, require both speed and adaptability of the mobile refueling units in order to be able to quickly receive, transfer, and dispense fuel.

What is desired, therefor, is a delivery system that can be mounted to a vehicle for mobile fuel delivery. What is further desired is a fuel delivery system that is multifunctional, such that various fuel pumping configurations can be accomplished with the same assembly. What is also desired is such an assembly that is structural sound, yet sufficiently compact, to facilitate rapid and efficient mobility.

DETAILED DESCRIPTION OF THE INVENTION

The following detailed description illustrates the technology by way of example, not by way of limitation, of the principles of the invention. This description will enable one skilled in the art to make and use the technology, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. One skilled in the art will recognize alternative variations and arrangements, and the present technology is not limited to those embodiments described hereafter.

FIG. 1 illustrates one exemplary embodiment of an assembly (20) in accordance with the invention. A manifold (30) is mounted in a frame (40), which can in turn be mounted to a vehicle, as is further described below.

As shown in FIGS. 2A-B, the manifold (30) includes a series of conduits that interconnect a pump (50), which is powered by a diesel engine (60), a filter separator (54), a main inlet (58), an auxiliary inlet (62), and a main outlet (66). In certain advantageous embodiments, one or more hose connections (72, 74) are also interconnected therewith.

Preferably, the manifold conduits take the form of piping made of aluminum, stainless or galvanized steel, or schedule 80 PVC. In preferred embodiments, the pump (50) is capable of providing fuel flow rates between 40 gallons per minute (GPM) and 750 gallons per minute (GPM), and the filter separator (54) is capable of filtering fuel up to 350 gallons per minute (GPM).

The assembly includes a number of valves positioned at various locations along the manifold's conduits, which can be switched between open and closed positions in order to modify the direction of fluid flow. By actuating these valves in specific combinations, many different configurations can be achieved.

A first main valve (82) is positioned such that, when in an open position, fluid flows from the main inlet (58) to the pump (50). Near the outlet of the pump (50), a second main valve (84) and third main valve (86) are positioned such that, when the second main valve (84) is in an open position and the third main valve (86) is in a closed position, fluid flows from the pump (50) to an inlet of the filter separator (54), whereas, when the third main valve (86) is in an open position and the second main valve (84) is in a closed position, fluid flows from the pump (50) toward the main outlet (66).

Near each hose connection (72, 74) is a corresponding main hose connection valve (100, 102), and a fourth main valve (88) is positioned such that, when the one or more main hose connection valves (100, 102) are open and the fourth main valve (88) is closed, fluid flows from the an outlet of the filter separator (54) to the one or more hose connections, whereas, when the main hose connection valves (100, 102) are closed and the fourth main valve (88) is open, fluid flows from an outlet of the filter separator (54) through the fourth main valve (88).

A fifth main valve (90), and a sixth main valve (80) are positioned such that, when the fifth main valve (90) is in an open position and the sixth main valve (80) is in a closed position, fluid flows from the fourth main valve (88) towards the main outlet (66), whereas, when the sixth main valve (80) is in an open position and the fifth main valve (90) is in a closed position, fluid flows from the fourth main valve (88) to the main inlet (58).

Near each hose connection (72, 74) is also a corresponding auxiliary hose connection valve (96, 98) such that, when the valves (96, 98) are in an open position and the corresponding main hose connection valve (100, 102) is closed, fluid entering through the hose connection (72, 74) will flow through the corresponding auxiliary hose connection valve (96, 98).

A main outlet valve (94) is positioned near the main outlet (66), such that, when the valve (94) is in an open position, fluid can flow out through the main outlet (66). An auxiliary inlet valve (92) is positioned near the auxiliary inlet, such that, when the valve (92) is in an open position, fluid can flow in through the auxiliary inlet (62).

Due to the unique design of the manifold, by opening specific combinations of valves, one is able to create a variety of different flow paths for the fluid, and is able to achieve at least ten different configurations, as is described in further detail below.

In certain advantageous embodiments, the valves (92), (94), (96), (98), (100), and (102), which are located adjacent to external connections, are manually activated valves, in order to minimize size and cost, while the internal valves (80), (82), (84), (86), (88), and (90) are pneumatically-actuated valves, due to the more restricted accessibility to the valves when the manifold (30) is mounted in the frame (40). These air-operated valves are each supplied with air via a hose (70) for this purpose. Both the manually operated and the pneumatically operated valves may be of the butterfly, gate, or ball type.

Referring to FIGS. 3A-B, a configuration for bulk delivery of fuel supplied by a vehicle's tank and subsequently filtered is depicted. In this configuration, air actuated valve (82), air actuated valve (84), air actuated valve (88), and air actuated valve (90), as well as manual valve (94) adjacent the main outlet (66) are all open, such that fuel travels along fluid pathway A. In fluid pathway A, the fuel travels through the main inlet (58), through valve (82) and into the pump (50), out of the pump (50) and through valve (84), and into the filter separator (54). After the fuel exits the filter separator (54), it flows through valve (88), through value (90), and through valve (94), before exiting through the main outlet (66).

Referring to FIGS. 4A-B, a configuration for bulk delivery of fuel supplied by a vehicle's tank but not filtered is depicted. In this configuration, air actuated valve (82), air actuated valve (86), and manual valve (94) are all open, and fuel travels along fluid pathway B. In fluid pathway B, the fuel travels through the main inlet (58), through valve (82) and into the pump (50), out of the pump (50) and through valve (86), then through valve (94), before exiting through the main outlet (66).

Referring to FIGS. 5A-B, a configuration for bulk delivery of fuel supplied by an auxiliary source and subsequently filtered is depicted. In this configuration, manual valve (92) located adjacent the auxiliary inlet (62) is open, and air actuated valve (84), air actuated valve (88), air actuated valve (90), as well as manual valve (94) adjacent the main outlet (66), are also open, such that fuel travels along fluid pathway C. In fluid pathway C, the fuel travels through the auxiliary inlet (62), through valve (92) and into the pump (50), out of the pump (50) and through valve (84), and into the filter separator (54). After the fuel exits the filter separator (54), it flows through valve (88), valve (90), and valve (94), before exiting through the main outlet (66).

Referring to FIGS. 6A-B, a configuration for bulk delivery of fuel supplied by an auxiliary source and not filtered is depicted. In this configuration, manual valve (92) located adjacent the auxiliary inlet (62), air actuated valve (86), and manual valve (94) adjacent the main outlet (66) are open, and fuel travels along fluid pathway D. In fluid pathway D, the fuel travels through the auxiliary inlet (62), through valve (92) and into the pump (50), out of the pump (50) and through valve (86), then through valve (94), before exiting through the main outlet (66).

Referring to FIGS. 7A-B, a configuration for a system purge including filtering is depicted. In this configuration, manual valves (96, 98) adjacent the hose connections (72, 74) are open, and air actuated valve (84), air actuated valve (80), and air actuated valve (88) are also open, such that fuel travels along fluid pathway D. In fluid pathway D, fluid is drawn through the hose connections (72, 74) and travels through valves (96, 98) to a purge junction (104), into the pump (50), out of the pump (50) and through valve (84), and into the filter separator (54). The fluid then exits the filter separator (54), flows through valve (88), through valve (80), and through the main inlet (58) to the tank.

Referring to FIGS. 8A-B, a configuration for a system purge that does not include filtering is depicted. In this configuration, manual valves (96, 98) adjacent the hose connections (72, 74) are open, and air actuated valve (86), air actuated valve (90), and air actuated valve (80) are open, such that fuel travels along fluid pathway E. In fluid pathway E, fluid is drawn through the hose connections (72, 74) and travels through valves (96, 98) to a purge junction (104), into the pump (50), out of the pump (50) and through valve (86), through valve (90), through valve (80), and through the main inlet (58) to the tank.

Referring to FIGS. 9A-B, a configuration for self-loading with filtering is depicted. In this configuration, manual valve (92) adjacent the auxiliary inlet (62) is open, and air actuated valve (84), air actuated valve (88), and air actuated valve (80) are also open, such that the fuel travels along fluid pathway G. In fluid pathway G, the fuel travels through the auxiliary inlet (62), though valve (92) and into the pump (50), out of the pump (50) and through valve (84), and into the filter separator (54). The fuel flows out of the filter separator (54), through valve (88), through valve (80), and then out through the main inlet (58) to the tank.

Referring to FIGS. 10A-B, a configuration for self-loading without filtering is depicted. In this configuration, manual valve (92) adjacent the auxiliary inlet (62) is open, and air actuated valve (86), air actuated valve (90), and air actuated valve (80) are also open, and the fuel travels along fluid pathway H. In fluid pathway H, the fuel travels through the auxiliary inlet (62), through valve (92) and into the pump (50), out of the pump (50) and through valve (86), through valve (90), through valve (80), and then through the main inlet (58) to the tank.

Referring to FIGS. 11A-B, a configuration for retail delivery of fuel supplied by the vehicle's tank and subsequently filtered is depicted. In this configuration, air actuated valve (82), air actuated valve (84), as well as manual valve (100) and/or manual valve (102) are open, and the fuel travels along fluid pathway I. In fluid pathway I, the fuel travels through the main inlet (58), through valve (82) and into the pump (50), out of the pump (50) and through valve (84), and into the filter separator (54). The fuel then exits the filter separator (54) and flows through valve (100) and/or (102) to one or more connected hoses to provide fuel at a lower gallon per minute rate.

Referring to FIGS. 12A-B, a configuration for retail delivery of fuel supplied by an auxiliary source and subsequently filtered is depicted. In this configuration, manual valve (92) adjacent auxiliary inlet (62) is open, and air actuated valve (84), and manual valve (100) and/or manual valve (102) are also open, such that the fuel travels along fluid pathway J. In fluid pathway J, the fuel travels through the auxiliary inlet (62), though valve (92) and into the pump (50), out of the pump (50) and through valve (84), and into the filter separator (54). The fuel then exits the filter separator (54) and flows through valve (100) and/or (102) to one or more connected hoses to provide fuel at a lower gallon per minute rate.

Any valves not indicated to be an open position in the above configurations are in a closed position.

Referring back to FIG. 2A, in the particular embodiment shown, a sensor (110) is located at the outlet of the filter separator (54) to measure the discharge pressure (psi), and a sensor (112) is located near the inlet to the pump (50) to measure the negative pressure (psi). Various sensors may be employed in this way throughout the assembly to provide information regarding various parameters, including fuel level, engine temperature, oil pressure, water level, engine RPM, battery voltage, pump inlet pressure, pump outlet pressure, and filter separator differential pressure.

As shown in FIG. 13, the frame (40) of the pumping assembly is designed to be mounted to the back of a vehicle (120). Though the assembly is shown mounted to a fuel tanker truck, it can be mounted to different vehicles, including trailers, flatbeds, and the like. In the embodiment shown, hoses (130, 132) are mounted on the lower portion of the frame (40). These hoses (130, 132) are connectible to the hose connectors (72, 74), typically for retail delivery.

In the particular embodiment illustrated, a control box (150) containing an internal display (154) is mounted between the hoses (130, 132), as is a button panel (158) containing a set of buttons corresponding to the pneumatically operated valves (80), (82), (84), (86), (88), and (90) in order to control those valves. The sensors (110, 112), or any other sensors, communicate with the control box (150) via hardwire or wirelessly in order to provide it with the information measured by those sensors, which is displayed on the display panel (154).

A battery box (140) mounted to the frame (40), which contains two deep cycle batteries to produce a 24 volt system, provides necessary power.

By utilizing the above-described controls and sensors, the system is able to control, monitor, and display various parameters of the assembly, including valve position, flow rate, fuel level, engine temperature, oil pressure, engine preheater, preheater indicator light, engine start/stop switch, water level warning light, control system illumination, engine RPM, engine hours, battery voltage, pump inlet pressure, pump outlet pressure, and filter separator differential pressure.

By using the aforementioned pumping assembly employing a specifically structured manifold with a sequence of strategically placed valves, one is able to switch between at least ten different pumping configurations to control the flow of fuel from a tanker or other vehicle, as needed at the time.

It should be understood that the foregoing is illustrative and not limiting, and that obvious modifications may be made by those skilled in the art without departing from the spirit of the invention. Although the invention has been described with reference to embodiments herein, those embodiments do not limit the scope of the invention. Accordingly, reference should be made primarily to the accompanying claims, rather than the foregoing specification, to determine the scope of the invention.
