Abstract

本发明涉及一种用于机动车的燃油箱(1)，其具有由换气装置(5)的分离器(15)和活性炭过滤器(13)构成的结构性单元。该结构性单元设置在用于收集燃油的腔(2)中，且具有用于容纳分离器(15)和活性炭过滤器(13)的共同的容器(6)。该容器(6)固定在燃油输送单元(4)上。

Description

用于机动车的燃油箱
技术领域
本发明涉及一种燃油箱，具有：用于收集机动车的燃油的腔；换气装置；活性炭过滤器以及用于输送燃油的燃油输送单元，其中该换气装置具有用于将液态的燃油与气体相分离的分离器。
背景技术
这种燃油箱通常具有大量的单独地安装在燃油箱外部的换气管，并由实践是已知的。用于将液态的燃油与气体相分离的分离器经常设置在燃油箱的注油管上。活性炭过滤器在大多情况下设置在燃油箱上或设置在燃油箱中，并通过另外的换气管与分离器连接。
这种已知的燃油箱的缺点在于：其体积非常大；以及在燃油箱外部设置换气装置的部件的这种布置促使燃油渗漏到外部环境中。
发明内容
本发明的目的在于，这样地改进一种在开头所述类型的燃油箱，即其结构特别紧凑且在很大程度上防止燃油泄漏到外部环境中。
该目的根据本发明这样地实现，即分离器和活性炭过滤器设计为结构性单元；且该结构性单元设置在腔的内部。
通过这种构造可以使与液态的或气态的燃油有联系的整个换气装置部件都设置在根据本发明的燃油箱的内部。由此而形成的燃油箱特别的紧凑。此外，基于本发明，燃油蒸汽泄漏到外部环境中的量保持在特别小的程度。
当由分离器和活性炭过滤器构成的结构性单元被固定在燃油输送单元上时，根据本发明的燃油箱的安装特别简单。此外，由分离器和活性炭过滤器构成的结构性单元和燃油输送单元由此可以经过唯一的装配口安装到根据本发明的燃油箱中。
当由分离器和活性炭过滤器构成的结构性单元具有共同的容器，且该容器具有隔板以用于将活性炭过滤器与分离器相分离时，根据本发明的燃油箱被设计得特别紧凑。
根据本发明的另一个有利的改进方案，当分离器和活性炭过滤器通过阀连接并且如果该阀设计为翻车安全阀和/或防溅安全阀时，能够可靠地避免燃油渗入到活性炭过滤器中。为了形成做为防溅安全阀，该阀可以具有例如浮子部件，该部件在接触到液态的燃油时关闭分离器与活性炭过滤器的连接部。阀形成为翻车安全阀防止了在具有根据本发明的燃油箱的机动车倾翻时，燃油经过活性炭过滤器流出。
根据本发明的另一个有利的改进方案，当分离器与通至腔的侧面区域中的换气管连接时，换气装置仅仅需要特别少的待装配部件。
根据本发明的另一个有利的改进方案，当在分离器中设置吸射泵并且如果该吸射泵通入到腔中时，将液态的燃油从分离器中排出就特别简单。
根据本发明的另一个有利的改进方案，当由分离器和活性炭过滤器构成的结构性单元与法兰间隔开，其中，该法兰封闭在燃油箱中的装配口时，有助于减少燃油排放。此外，结构性单元可以由此特别简单地穿过装配口被插入到根据本发明的燃油箱中。
如果在由分离器和活性炭过滤器构成的结构性单元旁边设置液位传感器，有助于进一步简化根据本发明的燃油箱的安装。
根据本发明的另一个有利的改进方案，当在分离器和活性炭过滤器的连接部中设置可控制的再生调节阀并且该再生调节阀设计为用于有选择地关闭或开启连接部时，可以根据所设想事件简单地再生活性炭过滤器。通过这种设计可靠地避免了由于与分离器的气体交换而对活性炭过滤器的再生造成的影响。
当活性炭过滤器可以通过被引导经过法兰的管与外部环境连接，以及可以利用再生管线与机动车的内燃机连接时，有助于进一步简化活性炭过滤器的再生。
附图说明
本发明允许大量的实施例。为了进一步说明本发明的基本原理，在附图中示出其中一个实施例，并在下面加以说明。图中示出：
图1是穿过根据本发明的燃油箱的示意性截面图，
图2是具有图1中的燃油箱的燃油输送单元的换气装置的视图，
图3是穿过结构性单元的示意性截面图，该结构性单元由换气装置和活性炭过滤器构成，且具有与图1中所示的燃油箱的相邻区域。
具体实施方式
图1示出用于机动车的燃油箱1，该燃油箱用于为未示出的内燃机供应燃油，并具有用于收集燃油的腔2和注油管3。燃油输送单元4和换气装置5设置在燃油箱1中。换气装置5具有紧靠燃油输送单元4设置的容器6和通至燃油箱1的主腔2的侧面区域中的换气管7。换气管7也可以具备其它未示出的、例如通至注油管3中的换气管。燃油输送单元4相对于燃油箱1的底部预加应力，并支承在封闭装配口8的法兰9上。
图2以透视图示出图1中的具有换气装置5的容器6的燃油输送单元4。换气装置5的容器6固定在燃油输送单元4上且固定有液位传感器10。此外，换气装置5的容器6通过通至外部环境的管线11和再生管线12与法兰9连接。再生管线12例如被引导至内燃机的未示出的抽吸管。
图3是出了在穿过换气装置5的容器6的截面图，在容器6中设置有活性炭过滤器13。因此，活性炭过滤器13和换气装置5构成了可预装配的结构性单元，该单元可以穿过装配口8安装到燃油箱1中。在容器6中具有隔板14以用于将分离器15与活性炭过滤器13相分离。分离器15将燃油与气体相分离，并具有吸射泵16。吸射泵16由图1中的燃油输送单元4通过过滤器17和止回阀18供应作为动力燃料的燃油，并将在分离器15中收集的燃油输送到燃油箱1中。分离器15与活性炭过滤器13通过阀19连接。阀19设计为翻车安全阀(Roll-Over-Ventil)，并在机动车翻倒时，防止燃油从燃油箱1中经过活性炭过滤器13和经过从活性炭过滤器13通至外部环境的管11流出。此外，阀19设计为防溅安全阀，并例如在转弯行驶时，防止在分离器15中所收集的燃油溢出到活性炭过滤器13中。此外，在分离器15与活性炭过滤器13的连接部中设置再生调节阀20。如果活性炭过滤器13被再生，则该再生调节阀20可以关闭。此外，图3示出，由分离器15和活性炭过滤器13构成的结构性单元的容器6与法兰9间隔开。
