    • The fuel injector has a housing that is formed from at least one nozzle tension nut, a first injector module and a second injector module. The first injector module and the second injector module adjoin one another and are disposed in the nozzle tension nut. A fuel high-pressure bore is led through the first injector module and the second injector module. A fuel return bore is disposed in the housing. Contact surfaces between the injector modules form a first gap that adjoins the high-pressure bore. Contact surfaces between the nozzle tension nut and the injector modules form a second gap that is connected to the first gap. The return line adjoins the second gap for the discharge of fuel that has entered the second gap from the high-pressure bore via the first gap. The fuel injector is such that the second gap is sealed off relative to the surroundings of the fuel injector.
    • 燃料喷射器具有由至少一个喷嘴张紧螺母,第一喷射器模块和第二喷射器模块形成的壳体。 第一注射器模块和第二注射器模块彼此相邻并且设置在喷嘴张紧螺母中。 燃料高压孔被引导通过第一注射器模块和第二注射器模块。 燃料回流孔设置在壳体中。 喷射器模块之间的接触表面形成邻接高压孔的第一间隙。 喷嘴张紧螺母和喷射器模块之间的接触表面形成连接到第一间隙的第二间隙。 返回管线邻接第二间隙,用于经由第一间隙从高压孔进入第二间隙的燃料排放。 燃料喷射器使得第二间隙相对于燃料喷射器的周围被密封。
