    • The invention relates to sealing means (2) for a fuel-injection valve (1) that can be introduced into a receiving bore (3) of a cylinder head (4) of an internal combustion engine, said valve being used for directly injecting fuel into a combustion chamber (7) of the internal combustion engine. The sealing means comprise a sealing element (17), which encloses the circumference of a nozzle body (5) of the fuel-injection valve (1). The sealing means (2) comprise a base body (15) with an axial cavity (16), through which the nozzle body (5) extends. The base body (15) also has an annular recess (18) connected to the cavity (16), into which the sealing element (17) is introduced. A first bearing surface (51) of the base body (15) abuts a front face (58) of the fuel-injection valve (1), at least indirectly, and a second bearing surface (57) lying opposite the first (51) at least indirectly abuts a step (11) of the receiving bore (3).
    • 的密封装置(2),用于在接收孔(3)的气缸盖(4)可被插入用于将燃料直接喷射的内燃发动机的燃料喷射器(1)到所述内燃机的燃烧室(7)具有密封元件(17),其中,(a喷嘴体 5)的燃料喷射阀的围绕(1)沿周向。 在这种情况下,密封装置(2)包括一个基体(15)具有轴向凹槽(16),通过它延伸的喷嘴主体(5)。 所述基体(15)还包括一具有连接到被引入到其中的密封元件(17)的环形凹槽(18)的凹槽(16)。 所述基体(15),其具有第一接触表面(51)至少间接地在所述燃料喷射阀的端面(58)(1)和与第二,第一邻接表面(51)的轴承表面(57)至少间接地相反(在步骤11中 接纳孔(AN)的3)。
