    • The invention relates to an injector (1) for injecting fuel into a combustion chamber of an internal combustion engine, in particular a common rail injector, with an injection valve element (9) which can be adjusted between a closed position and an open position which allows fuel to flow into the combustion chamber depending on the fuel pressure in a control chamber (11) and a control valve (21) provided in the control chamber (11) having a control valve element (22) adjustable relative to a control valve seat (28) provided on an injector component (13) by means of an actuator (31) guided on the outer circumference thereof by means of a guide component (33). According to the invention, the guide component (33) contacts a second centering surface (39) of eh injector component (13) with a first centering surface (38).

    • The invention relates to a switching valve for injectors, particularly for fuel injectors (1), comprising a closing element (31), by means of which a control arm (9) for actuating an injection valve member (3) can be relieved of pressure. The closing element (31) is actuated by a magnetic actuator comprising a magnet assembly (53) and an armature (51). The armature (51) is displaceably guided on a guide element (49) adjacent to the closing element (31), and, when the switching valve (17) is open, a gap is formed between the armature (51) and a front face (71) of the closing element (31) acting as a lower stop (57), by which the strike of the armature (51) against the front face (71) of the closing element (31) is damped.
    • 用于喷射器的切换阀技术领域本发明涉及一种用于喷射器的切换阀,尤其是用于燃料喷射器(1)的切换阀,其包括关闭元件(31),通过该关闭元件可以释放用于操作喷射阀元件(3)的控制臂(9) 。 封闭元件(31)由包括磁体组件(53)和电枢(51)的磁性致动器致动。 衔铁(51)在靠近封闭元件(31)的引导元件(49)上可移动地引导,并且当开关阀(17)打开时,在衔铁(51)和前表面 (31)的侧壁(71)充当下部止动件(57),衔铁(51)撞击关闭元件(31)的前表面(71)的撞击被阻尼。
