技术领域technical field

本发明涉及用于带有第一和第二鞍型区域的鞍型贮存箱的燃料输送设备。The present invention relates to a fuel delivery device for a saddle storage tank having first and second saddle regions.

背景技术Background technique

在现有技术中，以不同的构型公开了燃料输送设备。例如文献DE 10 2010 061813 A1示出了带有抽吸射流泵的燃料输送设备，该抽吸射流泵具有成本特别低的和有利于安装的结构。但是在车辆中，不久前大力地使用所谓的鞍型贮存箱，在这些油箱中，第一和第二鞍型室借助桥式的、弧形的连接区域相互连接。在这样的鞍型贮存箱中产生这样的问题：燃料输送单元通常仅布置在其中一个鞍型室中并且燃料必须从第二鞍型室送入第一鞍型室，以便能够实现燃料的完全输送。这里，理论上能够在第二鞍型室中设置第二燃料输送单元。但是由于成本原因，这并非优选的解决方案。In the prior art, fuel delivery devices are known in different configurations. For example, document DE 10 2010 061813 A1 shows a fuel delivery device with a suction jet pump, which has a particularly cost-effective and installation-friendly design. In vehicles, however, so-called saddle tanks have recently been used extensively, in which the first and second saddle chambers are connected to one another by means of bridge-shaped, arc-shaped connecting regions. The problem arises in such saddle tanks that the fuel delivery unit is usually only arranged in one of the saddles and the fuel has to be fed from the second saddle into the first saddle in order to be able to achieve a complete delivery of the fuel . Here, it is theoretically possible to arrange a second fuel delivery unit in the second saddle chamber. But for cost reasons, this is not a preferred solution.

因此值得期望的是：提供尽可能简单的方案用于将燃料从鞍型贮存箱的两个鞍型室中输送。It is therefore desirable to provide as simple a solution as possible for delivering fuel from the two saddle chambers of the saddle storage tank.

According to a first embodiment, the second nozzle is connected to the inlet pipe connection 13 for the propulsion pipe 6 .

具体实施方式detailed description

本发明的优选实施方式：Preferred embodiments of the present invention:

接下来，参照图1详细描述根据本发明第一优选实施例的燃料输送设备1。Next, a fuel delivery apparatus 1 according to a first preferred embodiment of the present invention will be described in detail with reference to FIG. 1 .

如图1示意性示出地一样，燃料输送设备1布置在鞍型贮存箱2中。鞍型贮存箱2包括第一鞍型室21、第二鞍型室22和桥式连接区域23，该连接区域将两个鞍型室相互连接。As shown schematically in FIG. 1 , a fuel delivery device 1 is arranged in a saddle tank 2 . The saddle storage tank 2 comprises a first saddle chamber 21 , a second saddle chamber 22 and a bridge connection area 23 connecting the two saddle chambers to each other.

燃料输送设备1包括输送罐3，在该输送罐中布置有燃料泵4和用于充注输送罐3的预输送模块。预输送模块包括带有第一模块构件11和第二模块构件12的模块单元10，之后还将详细描述这些模块构件。The fuel delivery system 1 comprises a delivery tank 3 in which a fuel pump 4 and a pre-delivery module for filling the delivery tank 3 are arranged. The pre-delivery module comprises a modular unit 10 with a first module component 11 and a second module component 12, which will be described in detail later.

燃料泵4将燃料从输送罐3中经燃料输送管道5输送到内燃机100。A fuel pump 4 delivers fuel from a delivery tank 3 to an internal combustion engine 100 via a fuel delivery line 5 .

模块单元10包括两个模块构件11，12，这些模块构件优选借助注塑制成。在此，模块单元10包括第一抽吸射流泵7和第二抽吸射流泵8。第一抽吸射流泵7包括第一混合管71和第一喷嘴72。第二抽吸射流泵8包括第二混合管81和第二喷嘴82。推进管道6从燃料输送管道5分支并且引向第一喷嘴72和第二喷嘴82。换言之，用于抽吸射流泵7,8的推进剂从燃料输送管道5分支。第一混合管71具有入口开口73，该入口开口经未示出的管道与第一鞍型室21连接。第二混合管81经燃料管道9与第二鞍型室22连接。The modular unit 10 comprises two modular components 11 , 12 which are preferably produced by injection moulding. The modular unit 10 here comprises a first suction jet pump 7 and a second suction jet pump 8 . The first suction jet pump 7 includes a first mixing tube 71 and a first nozzle 72 . The second suction jet pump 8 includes a second mixing tube 81 and a second nozzle 82 . The propulsion line 6 branches off from the fuel delivery line 5 and leads to a first nozzle 72 and a second nozzle 82 . In other words, the propellant for the suction jet pumps 7 , 8 branches off from the fuel delivery line 5 . The first mixing tube 71 has an inlet opening 73 which is connected to the first saddle chamber 21 via a line, not shown. The second mixing tube 81 is connected to the second saddle chamber 22 via the fuel pipe 9 .

因此，第一抽吸射流泵7用于将燃料从第一鞍型室21中抽吸并且第二抽吸射流泵7用于将燃料从第二鞍型室21中抽吸。Thus, the first suction jet pump 7 is used to suck fuel from the first saddle chamber 21 and the second suction jet pump 7 is used to suck fuel from the second saddle chamber 21 .

除了推进管道6的一部分6a外，第一模块构件11还包括第一混合管71和第二混合管72。这两个混合管71，81在此并排地并且相互平行地布置。混合管的两个端部在此这样布置：能够实现将燃料输送到输送罐3中，燃料泵4从该输送罐中抽吸。In addition to a part 6 a of the propulsion duct 6 , the first modular component 11 also includes a first mixing tube 71 and a second mixing tube 72 . The two mixing tubes 71 , 81 are here arranged side by side and parallel to one another. The two ends of the mixing tube are arranged in such a way that it is possible to feed fuel into the delivery tank 3 from which the fuel pump 4 sucks in.

第二模块构件12包括用于推进管道6的输入管道接口13、第一抽吸射流泵7的第一喷嘴72、第二抽吸射流泵8的第二喷嘴82、用于第二混合管81的混合管接口14和用于燃料管道9的燃料接口15。The second module component 12 comprises the inlet line connection 13 for the propulsion line 6, the first nozzle 72 of the first suction jet pump 7, the second nozzle 82 of the second suction jet pump 8, the second mixing tube 81 The mixing tube connection 14 and the fuel connection 15 for the fuel line 9.

两个模块构件11,12在此借助能松开的卡锁连接部相互连接(未在图示中示出)。另外也能够在第二模块构件12和输送罐3之间设置卡锁连接部。The two module components 11 , 12 are connected to one another here by means of a releasable snap connection (not shown in the illustration). In addition, a snap-in connection can also be provided between the second module component 12 and the delivery tank 3 .

因此，根据本发明能够实现用于将燃料从第二鞍型室22中抽吸的简单的抽吸解决方案。两个喷嘴72,82在此借助相同的推进管道6运行。因此，根据本发明能够使用鞍型贮存箱2的整个燃料体积。According to the invention, therefore, a simple suction solution for pumping fuel out of the second saddle chamber 22 can be realized. Both nozzles 72 , 82 are operated here via the same propulsion line 6 . Thus, the entire fuel volume of the saddle tank 2 can be used according to the invention.

图2示出根据本发明的第二实施例的燃料输送设备。与第一实施例不同，在第二实施例的情况下，第二鞍型室22借助产生压力的布置被排空(压力输送)。对此，第二抽吸射流泵8布置在第二鞍型室22中。Figure 2 shows a fuel delivery device according to a second embodiment of the invention. In contrast to the first embodiment, in the case of the second embodiment, the second saddle chamber 22 is evacuated by means of a pressure-generating arrangement (pressure delivery). For this purpose, the second suction jet pump 8 is arranged in the second saddle chamber 22 .

如图2可见，在第二模块构件12上布置有附加的推进剂出口16，在该推进剂出口上布置有第二推进管道17。第二推进管道17将推进燃料向着第二喷嘴82导入第二鞍型室22中。在第二鞍型室中，燃料被导入到在那里设置的混合管18中并且经燃料管道9引向第二模块构件12的燃料接口15。从燃料接口15处将这样被输送的燃料引入在第二模块构件12中的第二混合管81中并且能够在那里流出到输送罐3中。燃料接口15与第二抽吸射流泵8的第二混合管81连接。As can be seen in FIG. 2 , an additional propellant outlet 16 is arranged on the second module component 12 , on which a second propulsion duct 17 is arranged. The second propulsion duct 17 conducts propellant fuel into the second saddle chamber 22 towards the second nozzle 82 . In the second saddle chamber, the fuel is introduced into a mixing tube 18 arranged there and via the fuel line 9 to the fuel connection 15 of the second module component 12 . The fuel delivered in this way is introduced from the fuel connection 15 into the second mixing tube 81 in the second module component 12 and can flow out there into the delivery tank 3 . The fuel connection 15 is connected to a second mixing line 81 of the second suction jet pump 8 .

因此，在第二实施例的情况下，第一模块构件11与在第一实施例中一样地构成。第二实施例的第二模块构件12包括输入管道接口13、混合管接口14、燃料接口15并且附加地包括推进剂出口16。由于第二抽吸射流泵8当前布置在第二鞍型室22中，第二模块构件12则因此也不包括第二喷嘴82。管道9的燃料经第二混合管81被引导，其中，根据第二实施例的第二混合管81根据图2不具有喷嘴82。In the case of the second exemplary embodiment, therefore, the first module component 11 is designed in the same way as in the first exemplary embodiment. The second module component 12 of the second embodiment comprises an inlet line connection 13 , a mixing tube connection 14 , a fuel connection 15 and additionally a propellant outlet 16 . Since the second suction jet pump 8 is now arranged in the second saddle chamber 22 , the second module component 12 therefore also does not include the second nozzle 82 . The fuel of the line 9 is guided via the second mixing tube 81 , wherein the second mixing tube 81 according to the second exemplary embodiment does not have nozzles 82 according to FIG. 2 .

因此，第二实施例能够实现燃料从在压力下的第二鞍型室22中向第二混合管81的输送，其中，相比第一实施例，体积流尤其能够更大。The second exemplary embodiment thus enables the delivery of fuel from the pressurized second saddle chamber 22 to the second mixing tube 81 , wherein the volume flow can in particular be greater than in the first exemplary embodiment.

因此，通过根据本发明的模块化结构能够视客户希望而定地提供第二模块构件12作为抽吸的变型方案(第一实施例)或作为处于压力下的变型方案(第二实施例)，而不必改变燃料输送设备的其它构件。在此，通过卡锁连接部能够提供非常简单的和低成本的以及有利于安装的燃料输送设备。因此，根据本发明能够仅通过更换第二模块构件12提供抽吸的或在压力下工作的、用于鞍型贮存箱的燃料输送设备。Thus, the second modular component 12 can be provided as a suction variant (first embodiment) or as a pressurized variant (second embodiment), depending on the customer's wishes, thanks to the modular construction according to the invention, No other components of the fuel delivery system have to be changed. In this case, a very simple and cost-effective as well as installation-friendly fuel delivery device can be provided by means of the snap-in connection. Thus, according to the invention, only by exchanging the second module component 12 , it is possible to provide a pumped or pressurized fuel delivery device for saddle tanks.
