用于燃料喷射装置的去耦合元件
摘要：
根据本发明的用于燃料喷射装置的去耦合元件的特征特别在于，实现一种噪声小的结构。燃料喷射装置包括至少一个燃料喷射阀和在缸盖中用于燃料喷射阀的接收孔以及在燃料喷射阀的阀壳体和接收孔的壁之间的去耦合元件。去耦合元件钵形或者说罐形地构造并且在此具有径向内部的贴靠区域，去耦合元件能借助径向内部的贴靠区域在径向内部贴靠在燃料喷射阀上。此外设置有至少一个另外的去耦合元件，所述另外的去耦合元件同样钵形或者说罐形地构造并且与所述去耦合元件处于直接接触中。根据本发明的燃料喷射装置特别适合于将燃料直接喷射到混合压缩的、外源点火的内燃机的燃烧室中。
摘要（英）：

A decoupling element for a fuel injection device is characterized in that a low-noise configuration is implemented. The fuel injection device includes at least one fuel injector and a receiving borehole in a cylinder head for the fuel injector and the decoupling element between a valve housing of the fuel injector and a wall of the receiving borehole. The decoupling element has a bowl- or cup-shaped configuration, and includes a radially inner contact area with which the decoupling element is radially inwardly placeable against the fuel injector. At least one further decoupling element is provided that has a bowl-shaped or cup-shaped configuration and is in direct contact with the other decoupling element. The fuel injection device is particularly suited for the direct injection of fuel into a combustion chamber of a mixture-compressing spark ignition internal combustion engine.
