Definitions
- the invention relates to an arrangement for transferring fuel from one or more secondary tanks to a main tank, according to the preamble of claim 1.
- the invention also relates to a vehicle comprising said arrangement.
- a large proportion of vehicles used for example to carry passengers and goods are powered by some kind of combustion engine in which a fuel in liquid form is converted to a necessary motion.
- the vehicle is therefore provided with one or more fuel tanks to hold sufficient fuel for a predetermined period of use of the vehicle.
- Vehicles with high fuel consumption and/or for which long intervals between refuellings are desirable often have two or more fuel tanks situated at appropriate locations where there is space in the vehicle, to increase the total volume of fuel the vehicle can carry.
- each secondary tank is connected to a main tank from which fuel is supplied to the vehicle's engine.
- the respective tanks are connected to the main tank by a hose which extends between the bottom of the respective fuel tank and the bottom of the main tank, and the transfer of fuel takes place by siphon action which equalises the fuel levels in the tanks.
- the object of the present invention is to eliminate the above problems. This object is achieved by an arrangement according to claim 1.
- the problems described above are solved by the return flow from the fuel-consuming unit, usually a combustion engine, being led to the main tank via a return line which is divided into a number of secondary lines each fitted with a venturi tube.
- the venturi tube comprises a passage with reduced cross sectional area which thereby increases the velocity of the return flow through the passage.
- the increased flow velocity in the passage then induces in the transfer line a suction which can be utilised to transfer fuel from the secondary tank or secondary tanks to the main tank.
- the ancillary space in the main tank is a delineated space provided with drainage to return fuel from the ancillary space to the main tank when the ancillary space is overfilled.
- This embodiment increases the arrangement's reliability in that the ability to continuously drain fuel back from the ancillary space to the main tank prevents overfilling of the ancillary space which might otherwise result in leakage.
- the ancillary space is separated from the fuel tank by a wall which has an aperture situated in the upper part of the ancillary space and of the fuel tank.
- This embodiment represents a simple and reliable arrangement with continuous and guaranteed drainage of the ancillary space.
- each secondary tank and the main tank have a bottom surface in which the transfer line is connected. This transfer line connection means that almost all of the fuel in the tanks can be transferred to the ancillary space and then be used by the fuel-consuming unit.
- the bottom surface may be configured to slope towards the transfer line connection.
- a drainage hose runs between the main tank and at least one secondary tank. This embodiment ensures that the main tank is not overfilled, which might otherwise occur when there is a large quantity of fuel in the arrangement's tanks.
- the main tank and the respective secondary tanks are arranged at substantially the same height, and a pipe extends from the connection of the drainage hose or drainage hoses in the bottom surface of the secondary tank or secondary tanks such that the mouth of the drainage hose is situated above the bottom surface.
- This form of drainage between the tanks has the advantage that as long as the fuel level in the main tank is above the mouth of the pipe in the secondary tank or secondary tanks, fuel continuously drains back from the main tank to the secondary tank or secondary tanks, but when the fuel level in the main tank is below the level of the mouth of the pipe, no further fuel will drain.
- This is very advantageous in that the fuel in the secondary tanks is thereby transferred to the main tank and can then be used for the fuel-consuming unit.
- the arrangement comprises a main tank and one secondary tank and the return line is divided into two secondary lines. This is a specific
- Figure 1 illustrates a schematic flow diagram for an embodiment of an arrangement according to the invention, as seen from above
- Figure 2 illustrates a basic configuration of a venturi tube
- Figure 3 illustrates a cross sectional view of an embodiment of a secondary tank and a main tank which form part of the arrangement according to the invention.
- FIG 1 illustrates schematically the flow of the fuel in an embodiment of an
- the fuel is transferred from the ancillary space 13 to a fuel-consuming unit 14 which may for example be a combustion engine.
- a fuel-consuming unit 14 which may for example be a combustion engine.
- Both the main tank 11 and secondary tank 12 are suspended at substantially the same height on a framework 15, which may for example be a vehicle framework.
- the relationship between the respective heights at which the secondary tank and main tank are situated is important for the satisfactory functioning of the arrangement according to the invention. This relationship is illustrated schematically in Figure 3.
- fuel is transferred continuously from the ancillary space 13 to the fuel-consuming unit 14 via a fuel line 16 by a fuel pump, not shown, which is usually situated close to the fuel-consuming unit 14.
- the pump is adapted to generate a fuel flow to the fuel-consuming unit 14 which is always greater than the latter's actual fuel consumption. This results in a certain quantity of fuel not being combusted in the unit. This unused surplus is returned to the ancillary space 13 via a return line 17.
- the return line 17 divides into two, or in certain cases more, mutually parallel secondary return lines 18 each leading to the ancillary space 13.
- the number of secondary return lines 18 corresponds to the total number of tanks, comprising the secondary tanks 12 plus the main tank 1 1, which form part of the arrangement. In the present case, this means two secondary return lines.
- a venturi tube 20 is arranged along each secondary return line 18. The venturi tube 20 illustrated schematically in Figure 2 and described in more detail later in the description is used to transfer fuel from the main tank 1 1 and the secondary tank 12 to the ancillary space 13 in the main tank 1 1.
- a transfer line 22 which extends from the bottom of the respective tank to any of the venturi tubes 20 is connected near the tank bottom or at the tank's lowest point to ensure that as much fuel as possible is transferred from the tank.
- Fuel tanks are usually provided with a bottom plug for cleaning out accumulated litter in them and for draining off any water present in them, and the existing aperture is with advantage used to connect the transfer line 22.
- the tank bottom may be provided with one or more surfaces sloping towards the outlet to guide all of the fuel in the tank to the mouth of the transfer line 22.
- the quantity of fuel transferred from the main tank 1 1 and the secondary tank 12 to the ancillary space 13 is always greater than that consumed by the fuel-consuming unit 14, which means that when the arrangement is in use the fuel level in the ancillary space 13 will always be higher than the level in the main tank 1 1, ensuring a reliable supply of fuel from the ancillary space 13 to the unit 14.
- the fuel is drawn from the lower part of the ancillary space 13 to ensure that the inlet to the line 16 is always below the fuel level in the ancillary space 13, even if the latter is not completely full of fuel.
- the top edge of the ancillary space 13 is open to the main tank 1 1, so when the fuel level in the ancillary space 13 reaches the aperture, any surplus fuel will drain back to the main tank 1 1 by flowing over the edge of the boundary wall 25.
- the ancillary space 13 constitutes only a small part of the main tank 1 1.
- the size of the ancillary space 13 in relation to the main tank 1 1 depends on the expected fuel requirement of the fuel-consuming unit 14 and on the volumes available for tanks.
- the fuel level in the ancillary space 13 drops until the respective surface levels in the main tank 1 1, the secondary tank 12 and the ancillary space 13 are equalised by siphon action through the connecting transfer line 22.
- a venturi tube 20 and the flow through it during use are illustrated schematically in Figure 2.
- the venturi tube comprises a longitudinal passage 21 , the cross-sectional area of which near the centre of the venturi tube is reduced relative to the cross-sectional area at the venturi tube's inlet and subsequently increases again to substantially the same as at the inlet.
- the reduction in cross-sectional area results in an increase in the flow velocity in this section of the passage 21, thereby inducing a suction in the transfer line 22 connected to the passage 21 near to the point where the cross-sectional area reaches its minimum.
- Figure 3 illustrates a cross-sectional view through the arrangement in Figure 1 to illustrate the relationship between the respective heights at which the tanks are situated.
- the secondary tank 12 and the main tank 11, in which the section runs through the ancillary space 13, are each suspended on the framework 15 by
- FIG. 3 illustrates conceivable fuel levels in the tanks during operation. The fuel is transferred continuously to the ancillary space 13, resulting in the higher fuel level in this space.
- a drainage hose 23 runs between the bottom of the main tank and the bottom of the secondary tank to prevent the main tank 1 1 being overfilled.
- a pipe 24 is connected to the drainage hose 23 in such a way that the latter's mouth in the secondary tank 12 is moved slightly upwards from the bottom of the secondary tank. The purpose of this pipe 24 is to ensure that, as long as the fuel level in the main tank 11 is above the height at which the mouth of the pipe is situated, fuel will drain continuously from the main tank 1 1 to the secondary tank 12 via the drainage hose.
