燃料喷嘴
摘要：
一种内燃机的燃料喷嘴，其具有喷嘴体(11)和定位在喷嘴体(11)中的喷嘴针(12)，其中，喷嘴体(11)为用作阀体的喷嘴针(12)这样提供阀座(13)，使得在燃料喷嘴关闭时喷嘴针(12)的区域(15)压向由喷嘴体(11)所提供的阀座(13)，其中，由喷嘴体(11)所提供的阀座(13)成锥形轮廓，且其中，在燃料喷嘴关闭时压向由喷嘴体(11)所提供的阀座(13)的喷嘴针(12)的区域(15)由喷嘴针(12)的成球形轮廓的区段(17)来提供。
摘要（英）：

Fuel injection nozzle of an internal combustion engine, comprising a nozzle body (11) and a nozzle needle (12) located in said nozzle body (11), the nozzle body (11) providing a valve seat (13) for the nozzle needle (12) that serves as the valve body, such that, when the fuel injection nozzle is closed, a region (15) of the nozzle needle (12) pushes against the valve seat (13) provided by the nozzle body (11). The valve seat (13) provided by the nozzle body (11) has a conical contour and the region (15) of the nozzle needle (12) which pushes against the valve seat (13) provided by the nozzle body (11) when the fuel injection valve is closed is provided by a spherically contoured section (17) of the nozzle needle (12).
