技术领域
本发明涉及废气净化和再循环装置，尤其用于机动车辆废气系统。
背景技术
废气净化和再循环装置尤其用于减少热机的燃料消耗，特别是机动车辆的燃料消耗。
如现有技术中公知的、尤其是根据FR 3 041 033A1的一种净化和再循环装置比较笨重，难以安装到排气管路中。
本发明尤其旨在克服这种缺陷，提供一种紧凑型废气净化和再循环装置。
发明内容
为此，本发明尤其涉及一种废气净化和再循环装置，特别是用于机动车辆排气系统，废气净化和再循环装置具有：
-上游管，上游管沿第一方向X1延伸，上游管内接纳至少一个废气净化部件

-第二废气出口，第二废气出口与第二下游管连通；
并且，第一方向X1和第二方向X2之间形成的角γ包括在0°至90°之间。
因此，上游管和第一下游管在中间室的同一侧延伸，以致本发明的废气净化和再循环装置比现有技术的、特别是FR 3 041 033A1提出的装置结构更“紧凑”。
单独地或者根据任何可行的技术组合，本发明的装置还具有以下一个或多个特征：
-第一方向X1和第二方向之间形成的角γ包括在0至45°之间，最好在0至30°之间，优选地，基本上等于0°，更优选地，等于0°。

附图说明
根据下面参照附图仅作为示例给出的说明，本发明将得到更好的理解，附图如下：
-图1是根据本发明的一个实施例的净化和再循环装置的轴向截面示意图；
-图2是图1所示净化和再循环装置的立体图；
-图3是限定图1所示装置的中间室的第一壳体部分的俯视图；以及
-图4是限定图1所示装置的中间室的第二壳体部分的俯视示意图。
具体实施方式
图1和2示出废气净化和再循环装置10，其用于布置在尤其是机动车辆的排气系统中。
净化和再循环装置10具有上游管12，上游管沿第一方向X1延伸。该上游管12例如用于连接于排气系统的涡轮压缩机、通常是涡轮压缩发动机的出口，或者连接于常压发动机的排气歧管的出口。上游管12例如由不锈钢制造。
上游管12接纳至少一个废气净化部件14，例如串联的两个净化部件14。
因此，上游管12执行净化和再循环装置10的净化功能。
净化和再循环装置10还具有第一下游管16，第一下游管沿第二方向X2延伸，其中接纳至少一个传统的热交换器18。第一下游管16例如由不锈钢制造。
该第一下游管16例如用于连接于涡轮压缩发动机的所述涡轮压缩机的入口，或者常压发动机的蝶形阀壳体的下游，执行净化和再循环装置10的再循环功能。热交换器18如同其本身公知的那样，用于使废气的温度降低到一般为160℃的预定最高温度之下，再将所述废气注入到涡轮压缩机的入口，或者蝶形阀壳体的下游。
第一下游管16在布置于热交换器18下游的下游软管19中引出。该下游软管19具有主阀20，主阀20在关闭位置和释放位置之间活动，在关闭位置，废气不能在第一下游管16中流通，在释放位置，废气可以在第一下游管16中自由流通。
如图2所示，可选地，净化和再循环装置10具有旁通管22，旁通管22基本上平行于、最好平行于第一下游管16，也在下游软管19中引出。因此，旁通管22中的废气流动由主阀20的位置进行调节。
旁通管还可由传统类型的专用阀24封闭。该旁通管22如同本身公知的那样，用于保持足够高的温度(例如65℃以上)和防止在热交换器18中形成冷凝。专用阀24根据废气的温度开启或者封闭。
净化和再循环装置10还具有第二下游管28，第二下游管用于连接于废气出口管。第二下游管28例如由不锈钢制造。
净化和再循环装置10具有中间室30，中间室具有：
-废气入口32，废气入口在废气净化部件14的下游，例如直接在所述废气净化部件14的下游，与上游管12连通，
-第一废气出口34，其与第一下游管16连通，以及
-第二废气出口36，其与第二下游管28连通。
应当指出，第一废气出口34最好被过滤器37覆盖。该过滤器37例如由金属网形成。该过滤器37用于防止微粒尤其是陶器微粒从净化部件14向涡轮压缩发动机的涡轮压缩机，或者向常压发动机的蝶形阀壳体下游通过。
根据本发明，第一方向X1和第二方向X2之间形成的角γ包括在0°至90°之间，包含0°和90°。
应当指出，在现有技术中，第一方向和第二方向一般对齐，因而形成180°的角。
实际上，0°的角相当于使第一方向X1和第二方向X2平行，如同图1所示实施例的情况那样。在这种情况下，上游管12和第一下游管16彼此紧挨着平行延伸。
优选地，第一方向X1和第二方向X2之间形成的角γ包括在0至45°之间。
优选地，第一方向X1和第二方向X2之间形成的角γ包括在0至30°之间。
更优选地，角γ基本上等于0°，更加优选地等于0°。
可选地，第一方向X1和第二方向X2“之间”形成的角γ包括在45°至90°之间。
根据一个优选实施例，中间室30至少部分地由壳体限定，所述壳体由至少两个彼此固定的壳体部分30a、30b的组合件形成。
例如，壳体具有：
-第一壳体部分30a，第一壳体部分具有废气入口32和第一废气出口34，以及
-第二壳体部分30b，第二壳体部分具有第二废气出口36。
可选地，中间室30可由多个壳体部分形成。
第一壳体部分30a以仰视图、即从中间室30内侧，示意地示于图3。
该第一壳体部分30a例如基本上呈平面，但是，可选地，可具有任何可行的形状。如图3所示，废气入口32和第一废气出口34布置在该第一壳体部分30a中。用于连接于旁通管22的另一个孔口38，也布置在第一壳体部分30a中，位于第一废气出口34附近。
第二壳体部分30b以俯视图、即从中间室30内侧，示意地示于图4。
优选地，第二壳体部分30b具有一般向第二废气出口36收敛的凹形形状。该凹形侧面尤其示于图2。因为这种凹面，中间室30中的废气易于被导向第二废气出口36，当主阀20处于关闭位置时，尤其如此。换句话说，当主阀20处于关闭位置时，第一下游管16的存在不妨碍气流流向第二下游管28，废气流由凹面自然地导向第二废气出口36。
也应当指出，第二废气出口36最好布置成面对废气入口32。在不限于两个壳体部分的其他实施例中，也最好是这种情况。
此外，根据所述实施例，第二壳体部分30b带有废气导向件40。
可选地，废气导向件40可以不同地布置在中间室30中。
废气导向件40布置成将来自废气入口32的一部分废气导向第一废气出口34。因此，废气导向件布置在第二壳体部分30b上，至少部分地基本上面对第一废气出口34。因此，来自上游管12的、到达第二壳体部分30b的具有废气导向件40的区域的气体，由这些废气导向件40导向第一废气出口34。
