Description
技术领域
本发明涉及一种用于发动机的增压器的领域。
背景技术
增压器被用于增加由发动机生成的动力。增压器使用压缩机来增加向发动机供应的空气的压力或密度。增压器从发动机的曲轴通过带传动或链传动被机械地供能。为了增加增压器的性能,除了大气空气之外,还需要允许增压器具有额外的输入源。增压器可通达的另一空气源是来自发动机的废气。但是,由于废气中存在的杂质可能引起对增压器的部件的损坏,所以不能直接使用来自发动机的废气。因此,在空气和/或废气进入增压器之前,还需要净化机构。
现有技术的专利申请US8099957增压压缩机包括可旋转地安装在壳体中的多个转子、用于空气的第一入口、用于再循环的废气的第二入口、以及流动分离器。流动分离器布置在壳体的内部并且被配置为与多个转子中的至少一个转子形成可滑动的密封,所述可滑动的密封使第一入口至少部分地与第二入口流体地隔离并且阻碍其间的压力均衡。
附图说明
本发明的不同模式在说明书中详细公开并在附图中示出:
图1示出用于发动机的增压器;和
图2示出设有清洁材料的增压器。
具体实施方式
图1示出用于发动机(102)的增压器(200)。本文公开的增压器(200)从发动机(102)曲轴获得动力。在工作期间,增压器(200)收进空气和从废气再循环阀(EGR)(104)再循环的废气,并将其压缩至大于大气压的压力。结果是迫使更多的空气进入发动机(102)中。发动机(102)现在具有吸入更多燃料的能力,这对应于所供应的空气的体积的增加以及由此增加针对燃烧所供应的进气(charge)。这增加由发动机(102)产生的动力。到达增压器(200)的废气被灰尘和积炭填充,并且在其与大气空气一起被送回发动机(102)之前需要被净化。这在将在图2的详细描述中描述的清洁材料(206)的帮助下实现。
图2示出设有清洁材料(206)的增压器(200)。增压器(200)可以是鲁式增压器(200)。增压器(200)沿通向发动机(102)的入口定位,并且具有第一可旋转构件(202)和第二可旋转构件(204)。第一可旋转构件(202)和第二可旋转构件(204)安装在轴上,且该轴在驱动器的帮助下从发动机(102)的曲轴获得动力。第一可旋转构件(202)和第二可旋转构件(204)沿它们安装在其上的轴的相应轴线旋转。增压器(200)适于接收新鲜空气连同来自发动机(102)的再循环废气,并且设有清洁材料(206)。清洁材料(206)以设置成使得增压器(200)中第一可旋转构件(202)的至少一部分和第二可旋转构件(204)的至少一部分接触清洁材料(206)。第一可旋转构件(202)和第二可旋转构件(204)的轮廓使得清洁材料(206)能够容易地适配在其上。第一可旋转构件的至少一部分接触设置在第二可旋转构件(204)上的清洁材料(206)。第二可旋转构件(204)的至少一部分接触设置在第一可旋转构件(202)上的清洁材料(206)。
在可旋转构件的叶片相会的区域处形成叶间槽(interlobe trough)。从图2可看出,叶间槽是在第一可旋转构件和第二可旋转构件的叶片之间形成的凹陷。第一可旋转构件(202)将与设置在第二可旋转构件(204)的叶间槽(210)上的清洁材料(206)接触,且反之亦然。经由EGR阀(104)接收的废气由于第一可旋转构件(202)和第二可旋转构件(204)的旋转被抽吸入增压器(200)中,由于该抽吸作用,废气微粒得以沉积在清洁材料(206)上。存在于废气中的颗粒被清洁材料(206)去除。废气和大气空气的加压发生在第一可旋转构件(202)和第二可旋转构件(204)的圆凸与增压器(200)的壳体的内壁之间形成的空间内。
在实施例中,清洁材料(206)可以由橡胶制成。选择清洁材料(206)以便具有良好的耐磨性质和耐热性。清洁材料(206)设在第一可旋转构件(202)和第二可旋转构件(204)的叶间槽(208)和(210)上。清洁材料(206)可以胶粘于第一可旋转构件(202)和第二可旋转构件(204)的叶间槽(208)和(210)上。清洁材料(206)可压配合和/或卡扣配合于第一可旋转构件(202)和第二可旋转构件(204)的叶间槽(208)和(210)上。替代性地,清洁材料(206)通过包括销、螺钉、螺母和螺栓布置等的组合配合于第一可旋转构件(202)和第二可旋转构件(204)的叶间槽(208)和(210)上。
应当理解的是,就所使用的增压器的类型和将清洁材料附接到增压器的可旋转构件的叶间槽上的机构而言,在上述描述中解释的实施例仅是说明性的并且不限制本发明的范围。构想到许多这样的实施例以及在说明书中解释的实施例的其他修改和改变。本发明的范围仅由权利要求的范围的限制。
