Abstract
A feed unit (2) for feeding fuel out of a fuel tank (1) has a baffle (4) having two chambers (7, 13) which are connected to each other via a valve (14) designed as a throttle valve. A fuel pump (5) projects with a suction opening (6) into the first chamber (7). When the fuel tank (1) is emptied, the first chamber (7) is emptied. Over a period of time dependent on the throttling of the valve (14) fuel flows out of the second chamber (13) into the first chamber (7) and covers the suction opening (6). This ensures that, after the period of time, the fuel pump (5) can suck up fuel.
Description
- The invention relates to a feed unit for feeding fuel out of a fuel tank of a motor vehicle, having a baffle which has a first chamber for collecting fuel, having a fuel pump for sucking up fuel and having a fuel-pump suction opening arranged in the vicinity of the bottom of the first chamber of the baffle.
- Feed units of this type are frequently used in motor vehicles today and are known in practice. The chamber of the baffle generally has a bottom valve and is filled with fuel via a suction jet pump driven by the fuel pump. In addition, the baffle is arranged in a bottom region of the fuel tank, so that fuel can flow out of the fuel tank into the baffle via the bottom valve. The filling of the baffle via the suction jet pump ensures that, even if there is a very low fuel level in the fuel tank, the baffle is sufficiently filled with fuel.
- When the fuel tank is empty, the baffle is also emptied, as a result of which the fuel-pump suction opening emerges out of the fuel. Before the fuel pump can feed fuel again, sufficient fuel has to be poured into the fuel tank, for example by means of a jerrycan, for fuel to penetrate into the baffle. Only when the fuel-pump suction opening is resubmerged into the fuel can the fuel pump feed fuel. However, a minimum quantity of fuel is required for this.
- It is already been thought to arrange the baffle directly below a filler neck of the fuel tank. In this case, the baffle is filled at the beginning when the fuel is poured in. However, this arrangement of the baffle is frequently impossible in the case of fuel tanks nowadays, which are generally very shallow and angled.
- The invention is based on the problem of designing a feed unit of the type mentioned at the beginning in such a manner that, after the first chamber of the baffle is emptied, the fuel-pump suction opening is reliably covered with fuel.
- This problem is solved according to the invention by a second chamber being connected to the first chamber via a valve, and by the valve being a throttle valve, with the volumetric flow of fuel that is restricted by the valve being smaller than the volumetric flow fed by the fuel pump.
- This design makes it possible for the first chamber to be initially emptied, as in the case of the known feed unit, after the fuel tank has been emptied. Over a period of time which is dependent on the throttling action of the valve, fuel flows out of the second chamber into the first chamber and covers the fuel-pump suction opening. Feeding of the fuel pump is ensured by the invention. If, at the same time, a small quantity of fuel is put into the fuel tank, for example via the jerrycan, the feed unit according to the invention is capable of feeding the topped-up fuel.
- The feed unit according to the invention has a particularly low outlay on installation if the second chamber is manufactured integrally with the baffle.
- The second chamber could be arranged, for example, above the first chamber. However, according to another advantageous development of the invention, a filling of the second chamber can be ensured in a simple manner if the chambers are arranged at the same height. During the operation of the feed unit according to the invention, the second chamber, like the first chamber, can therefore be filled with fuel.
- The feed unit according to the invention has a particularly low structural outlay if the valve is arranged in a common wall of the first chamber and of the second chamber.
- According to another advantageous development of the invention, the baffle turns out to be particularly compact if the second chamber is designed as an annular chamber surrounding the first chamber. By this means, the feed unit according to the invention can be arranged in a simple manner even in particularly shallow and angled fuel tanks.
- According to another advantageous development of the invention, a reliable filling of the second chamber with fuel can be ensured in a simple manner if the second chamber is arranged within the baffle and the common wall between the first chamber and the second chamber is lower than an outer wall of the baffle. Fuel can thus flow from the first chamber into the second chamber.
- According to another advantageous development of the invention, the throttling of the fuel flowing from the second chamber into the first chamber requires a particularly low structural outlay if the valve is designed as an opening with a designated cross section.
- During the emptying of the first chamber, the valve has to throttle an over flow of fuel out of the second chamber into the first chamber, so that, when the fuel tank is empty, sufficient fuel remains in the second chamber. According to an advantageous development of the invention, sufficient throttling of the overflowing fuel can be achieved in a simple manner with customary volumes of known baffles if the valve throttles the volumetric flow, which flows from the second chamber into the first chamber, in such a manner that the level is equalized in three to five minutes after the fuel pump has stopped.
- According to another advantageous development of the invention, a sufficient fuel level in the first chamber after the fuel tank has been emptied can be reliably ensured if the second chamber has a volume of approximately 10-20% of the baffle volume.
- The invention permits numerous embodiments. To further clarify its basic principle, one of these is illustrated in the drawing and is described below. In the drawing
-
FIG. 1 shows schematically a longitudinal section through a fuel tank with a feed unit according to the invention arranged therein, -
FIG. 2 shows the feed unit according to the invention fromFIG. 1 after the fuel tank has been topped up with a small quantity of fuel. -
FIG. 1 shows schematically a longitudinal section through afuel tank 1 for a motor vehicle, having afeed unit 2 which is arranged in the bottom region and is intended for feeding fuel out of thefuel tank 1 to an internal combustion engine 3 of the motor vehicle. Thefeed unit 2 has abaffle 4 with an electrically operatedfuel pump 5 arranged therein. A suction opening 6 of thefuel pump 5 is arranged in the bottom region of afirst chamber 7 of thebaffle 4. Aforward flow line 8 leads from thefuel pump 5 to the internal combustion engine 3. Furthermore, asuction jet pump 9 is arranged in the bottom region and is supplied with fuel as the working fluid via afuel line 10 branching off from theforward flow line 8. Thesuction jet pump 9 sucks up fuel via abottom valve 11 arranged on thebaffle 4, and conveys the fuel into thefirst chamber 7 of thebaffle 4. - A
wall 12 for separating off thefirst chamber 7 from asecond chamber 13 is arranged in thebaffle 4. Thewall 12 has avalve 14 which is designed as a throttle valve and permits fuel to flow through into thefirst chamber 7. Thewall 12 separating thechambers outer wall 15 of thebaffle 4. This ensures that, during normal operation of thefeed unit 2, thesecond chamber 13 is at all times filled with fuel. - During the operation of the
feed unit 2, the internal combustion engine 3 is supplied with fuel and at the same time thebaffle 4 is filled with fuel via thesuction jet pump 9. The filling of thebaffle 4 with fuel is ensured as long as the fuel level in thefuel tank 1 reaches as far as thebottom valve 11. If the fuel level drops below thebottom valve 11, thefeed unit 2 supplies the internal combustion engine 3 with fuel until thefirst chamber 7 of thebaffle 4 is empty, as illustrated inFIG. 1 . The internal combustion engine 3 therefore does not obtain any fuel and the fuel pump stops. A topping-up of thefuel tank 1 with fuel takes place generally with a very small quantity. This quantity is generally sufficient in order to enable the level in thefuel tank 1 to rise again as far as thebottom valve 11. Since, however, the suction opening 6 of thefeed unit 2 in thebaffle 4 is arranged higher than the level in thefuel tank 1, thefeed unit 2 can only suck up fuel again and thesuction jet pump 9 can be supplied with fuel as the working fluid if the fuel level in thefirst chamber 7 is higher than the suction opening 6 of thefeed unit 2. - After the
first chamber 7 has been emptied, fuel present in thesecond chamber 13 flows via thevalve 14, which is designed as a throttle valve, slowly into thefirst chamber 7, as illustrated inFIG. 2 . The throttling action is configured in such a manner that the hydraulic equalizing operation lasts for three to five minutes. The flowing of the fuel through into thefirst chamber 7 causes the suction opening 6 to again be situated below the fuel level. Thefeed unit 2 can therefore supply the internal combustion engine 3 and thesuction jet pump 9 again with fuel. - The throttling of the volumetric flow, which is guided into the
first chamber 4, by thevalve 14, which is designed as a throttle valve, is dimensioned in such a manner that the fuel flows more slowly into thefirst chamber 7 than thefeed unit 2 feeds fuel to the internal combustion engine 3.
