Abstract

兹提出一种内燃机的燃料喷射系统,它具有一个由燃料高压泵供给燃料的高压储油器(1)。该高压储油器(1)具有空心球(2)的形状,该空心球由两个锻造的空的半球(3)和(4)焊在一起。锻造成形的固定元件(6,7,8,9)用于将高压储油器(1)固定在机动车上。

Description

燃料喷射系统
已有技术：
本发明涉及一种符合主权利要求所述种类的燃料喷射系统。在例如已由欧洲专利EP0507191公开的燃料喷射系统中，高压储油器由一个预制的管子组成，连接套筒被装在其上面，以连接燃料喷射阀及从燃料高压泵引来的高压管道。这种高压储油器体积相对庞大并因此需要大的安装空间。此外，它相对较重，且液压性能不佳。
本发明的优点：
在本发明的具有权利要求所述特征的燃料喷射系统中，其高压储油器仅需较小的安装空间、重量较小，其液压性能特别好。
图示：
本发明的一种实施形式在图中被示出并在下面的描述中被进一步说明。其中，
图1示出了带有固定元件的球形高压储油器的截面图，
图2示出了一接头单元，
图3示出了图1中的另一平面的截面图。
对实施例的说明：
高压储油器1具有空心球2的形状，该空心球由两个空的半球3和4组成。两个半球3和4采用锻造工艺制成，而后在其环形接触面上焊在一起。焊缝基准数为5。两个空的半球3和4也可以未示出的方式拧紧在一起。
两个空的半球3和4具有锻造时成形出的、彼此对应的耳柄型固定元件6，7，8及9，它们最好在焊接后各带有为未示出的固定螺栓而设的通孔10及11，借助它们，高压储油器1可固定在一汽车上。
如从图1中的截面图可以看出，垂直于焊缝5的平面4设有连接孔12、13、14及15，它们用于管道的连接，而这些管道用于使高压储油器1与电控喷射阀连通。既未示出管道，也未示出喷射阀。该四个连接孔12至15成对地在直径两端相对设置并各有一个内螺纹16，而每一个其直径更小、向内通过一个锥孔密封面17与内螺纹16连通的通孔18都与储油器内腔19连通。这种情况在图2中以放大比例示出。储油器内腔19例如具有约33cm3的容积。
图3示出了贯通球2的截面，它与图1中截面位于不同的平面上。可以看到一连接孔20，燃料高压输送泵的压力输入口可与该孔连通。与连接孔20相对还设有另一个连接孔21，在该孔内可拧入一个压力传感器或一个控制阀。
这两个连接孔20和21内也设有一个内螺纹16、一个密封面17和一个通孔18。在所有这些连接孔12至15和20及21内可以未示出的方式密封和牢固地装入高压管道，而这些高压管道则通过通孔18与储油器内腔19连通。

Claims (3)

1、用于内燃机的燃料喷射系统，它具有一个燃料高压泵，该泵供给一高压储油器燃料，燃料从该高压储油器被输送到电控喷射阀，从而喷射到自点火内燃机的燃烧室内，其中，高压储油器(1)设有供燃料输入和燃料输出的连通孔(12，13，14，15)及固定元件(6，7，8，9)，其特征是，高压储油器(1)具有空心球(2)的形状。
2、按照权利要求1所述的燃料喷射系统，其特征是，空心球形的高压储油器(1)由两个锻造空心半球(3和4)制成。
3、按照权利要求2所述的燃料喷射系统，其特征是，两个空的半球(3和4)在其环形接触面上借助焊缝(5)结合在一起。
