Definitions

• the present invention relates to a fuel tank for a wheeled motor vehicle comprising
• a fuel feed conduit having a fuel pick-up i nlet in said contai ner for pumping fuel th rough the conduit to an engine of the vehicle.
• the invention is not restricted to fuel tanks for any special type of wheeled motor vehicles, although it is especially directed to heavy motor vehicles, such as buses and trucks, having large fu el tanks which may contain 1 00 litre fuel or more when full , which is the reason why the invention will hereinafter mai nly be discussed for that application for illu minating the invention but not restricting it thereto.
• the invention covers fuel tanks for contain ing any conceivable fuel but is particularly directed to fuel tanks for contai ning fuel for compression ignited engines, such as diesel .
• BACKGROUND ART US 2014/0075732 A1 discloses a fuel tank of the type defined in the introduction having a said insert but in which the problem with a high said dead volume is still not solved.
• the object of the present invention is to provide a fuel tank of the type defined in the introduction being improved in at least some aspect with respect to such fuel tanks already known.
• This object is according to the invention obtained by providing such a fuel tank with the features listed in the characterizing part of appended patent claim 1.
• a float valve to control the connection of the fuel pick- up inlet of the fuel feed conduit and a said fuel permeable filter to be passed by fuel for entering said fuel pick-up inlet th is may be arranged in the bottom region of the container while sti ll ensu ring that no dirt will enter the fuel feed conduit and in particular that no air wil l enter the fuel feed conduit irrespectively of the inclination of said motor vehicle and by that of the fuel tank and how much fuel is in said tank, si nce when there is not fuel present around the float of the float valve th is will si nk to said bottom position and close the con nection of the fuel p ick-up inlet to the interior of the container.
• the float valve is arranged inside said insert and the bottom opening of the insert is configu red to al low fuel to enter an i nsert volu me surrounding said float valve through the first fuel permeable filter.
• the float valve may open said connection to the fuel feed conduit as long as there is fuel present on the bottom of the contai ner in the region of said insert.
• the insert is pro- vided with a pl ural ity of through-holes in walls thereof delimiti ng an inner volu me of the insert with respect to a surrounding contai ner volume and extend ing from said upper access hole to a bottom region of the container so as to allow fuel in the contai ner to flow therethrough into the i nsert.
• the insert may by this be fi lled with fuel when present to a certain level in said container.
• the float valve is arranged inside the insert and a second fuel permeable filter is arranged above the float valve so that this filter has to be passed by fuel throug h influence of the g ravitation for allowi ng fuel entering the insert throug h said through -holes to reach an i nsert volume surrounding said float valve. It is by that ensured that dirt in the fuel will not reach the float valve, since it has either to pass the first fuel permeable filter or the second permeable filter for reaching the float valve.
• the fuel tank comprises a fuel reserve tank arranged inside said insert and opening upwardly towards said access hole of the container so as to be fil led by fuel when filli ng the fuel tank with fuel through the access hole, the fuel reserve tank is provided with an overflow arrangement for overflow of fuel out into said container as of ob- tention of a certai n level of the fuel i nside the fuel reserve tank when filling the fuel tank by fuel , and a bottom region of the fuel reserve tank is provided with an outlet con nected to said fuel feed conduit downstream said fuel pick-up inlet thereof through a valve configured to be closed as long as fuel is present in said conduit upstream thereof and to open upon occurrence of no fuel inside said conduit so as to drain fuel from the fuel reserve tank when this occurs.
• valve in the connection of the fuel reserve tank to the fuel feed conduit is a pressure release valve configured to open upon occurrence of a negative pressure inside said conduit.
• the fuel tank is provided with means configu red to i ndicate the amount of fuel in the fuel tank, and these means comprise a member measuring the level to which the fuel reserve tank is filled.
• the emptying of the fuel reserve tank will pri ncipally be started when there is no fuel left in the container, and the member measu ring the level of the fuel in the fuel reserve tank wi ll by that i ndicate the amou nt of fuel left in the fuel tank with a high accuracy, so that the driver of the vehicle knows how far the vehicle may be driven without any risk of runni ng out of fuel .
• said insert is configured to receive a fuel return line entering the fuel tank through said upper access hole of the container to direct fuel from said fuel return li ne to enter the fuel reserve tank. It is by this ensured that the fuel reserve tank is kept filled u nti l the moment when nearly no fuel is left in the contai ner of the fuel tank.
• the fuel tank comprises a member configu red to removably secure said insert to the contai ner in the reg ion of said access hole, and the insert and said access hole are designed so as to allow the insert to be removed from the fuel tank throug h said access hole.
• the i nsert may be removed from the fuel tank for repai r or mai ntenance or exchange thereof increasing the service ability of the fuel tank.
• Fu rthermore, th is type of securing of the i nsert avoids welds, so that fastening of the insert may be accomplished by means making it possible to produce the i nsert by lig ht materials.
• the fuel tank is configured to be con nected to a compression ignited engine and to contai n for example diesel as fuel .
• the fuel tank according to the invention is particularly suitable for use in fuel systems of such engines being very sensitive to penetrating of ai r i nto the fuel system .
• the fuel tank has a volume maki ng it able to contai n more than 1 00 litre fuel and it is configured to be arranged i n a heavy wheeled motor veh icle, such as a truck or a bus.
• a fuel tank desig ned in accordance with the present invention may in such an embodiment reduce the dead volume with respect to known such fuel tanks considerably.
• said container has a dimension reachi ng and exceeding 300m m, 500mm , 1 000 mm , 1 500 m m or 1 800 mm in a di rection configured to be horizontal when said vehicle is arranged on a horizontal ground.
• a fuel tank with such an extension wi ll require a substantial amount of fuel in the fuel tank for ensuring that at least half of the bottom thereof is covered by fuel when the vehicle is standing on a steep road, so that a said dead vol ume may be reduced considerably by such a fuel tank designed according to the present invention .
• the invention also relates to a wheeled motor vehicle provided with a fuel tank according to the invention .
• Fig 1 is a schematic view illustrating a fuel tank accordi ng to an embodi ment of the i nvention .
• Fig 2 is an enlarged view of a float valve arranged in the fuel tank shown i n Fig 1 .
• the fuel tank comprises a container 3 config ured to provide the main volume for fuel of the fuel tank and an insert 4 removably secured by a securing member 5 to the container 3 at an access hole 6 of the container for filling the tank with fuel for i nserting the insert through this access hole 6 and remove it from the container through that hole.
• the insert 4 extends when secu red to the container from the upper access hole 6 to a bottom region 7 of the contai ner.
• the insert is provided with a pl urality of through -holes 8 in walls 9 thereof delimiting an inner volume 1 0 of the insert with respect to a surrounding container vol ume 1 1 and extending from the upper access holes 6 to a bottom region of the container so as to al low fuel in the container to flow through these holes 8 i nto the insert.
• the insert has a bottom 1 2 to be arranged next to the bottom 1 3 of the container and which is provided with an opening 1 4 covered by a fi rst fuel permeable filter 1 5 to let fuel entering the insert from below through that filter.
• a fuel feed conduit 1 6 for feeding fuel to an engine of the vehicle has a fuel pick-up inlet 1 7 located i nside the i nsert in the bottom reg ion thereof.
• This inlet 1 7 is connected to a float valve 1 8 (see now also Fig 2) having a float 1 9 to be lifted by fuel surrounding it inside the i nsert so as to lift a valve body 20 and opening a connection of the fuel pick-up inlet 1 7 to said filter 1 5 for enabling fuel to pass through said filter and into the fuel conduit.
• a float valve 1 8 see now also Fig 2
• a float 1 9 to be lifted by fuel surrounding it inside the i nsert so as to lift a valve body 20 and opening a connection of the fuel pick-up inlet 1 7 to said filter 1 5 for enabling fuel to pass through said filter and into the fuel conduit.
• a second fuel permeable filter 30 is arranged above the float valve 1 8 so that this fi lter has to be passed by fuel through influence of the gravitation for al lowing fuel enteri ng the insert through the holes 8 to reach an insert volume su rroundi ng the float valve.
• This second fuel permeable filter is arranged at a lower level than the lowermost of said through-holes 8.
• a fuel reserve tank 21 which may for instance have a volume of 1 5 - 1 00 litre depending on the container volu me, is arranged inside the i nsert 4 and opens upwardly towards the access hole 6 of the container so as to be filled by fuel when filling the fuel tank with fuel .
• the fuel reserve tank is provided with an overflow arrangement 22 for overflow of fuel out i nto the container as of ob- tention of a certain level of the fuel inside the fuel reserve tank when filling the fuel tank by fuel .
• a bottom region 23 of the fuel reserve tank 21 is provided with an outlet 24 con nected to the fuel feed conduit 1 6 downstream the fuel pick-up i nlet 1 7 thereof through a pressure release valve 25 configured to be closed as long as fuel is present in the conduit 1 6 upstream thereof, i .e. closer to the fuel pick-up inlet 1 7 connected to the float valve 1 8.
• the pressure release valve 25 is configu red to open upon occur- rence of negative pressure to a certain degree inside the conduit 1 6 so as to drain fuel from the fuel reserve tank when this occurs, which will happen when fuel is pumped through the conduit 1 6 to the engi ne and the float valve will close on emptying the container.
• a fuel return line 26 enters the fuel tank throug h the upper access hole 6 of the container to di rect fuel from this line to enter the fuel reserve tank.
• Means configured to i ndicate the amount of fuel i n the fuel tank comprises a member 27 measuring the level to which the fuel reserve tank is filled for sending information thereabout to a display 28 visible to a driver of the vehicle. The level of the surface of fuel in the fuel reserve tank will not start to sink from said overflow level before the fuel tank nearly only contains the fuel present in the fuel reserve tank, so that the member 27 may deliver a reliable indication of the amount of fuel left in the fu el tank to be used for calcu lating how far the vehicle may still be driven before having to refill the fuel tank.
• valve i n the connection of the fuel reserve tank to the fuel feed conduit may be of another type than in the embodiment described above, such as an electrically controlled valve controlled to open or close based on i nformation from sensors arranged to detect the fuel level arou nd the float valve.
